Bass Strait Maritime Heritage Survey Bathymetry 2m - 50m (CSIRO) in2019_v07 (AusSeabed:Bass Strait Maritime Heritage Survey Bathymetry 2m - 50m (CSIRO) in2019_v07)

RAN Hydrographic and Maritime Heritage Surveys 1) Conduct a modern survey in the primary shipping route through Bass Strait for the Australian Hydrographic Office (AHO). This survey will facilitate safe navigation for international and coastal shipping and improve confidence for subsurface navigation in Bass Strait. 2) Undertake mapping of historic shipwreck sites, in partnership with Heritage Victoria and the Australian National Maritime Museum (ANMM). The primary activity of the GSM investigation of historic shipwreck sites is to conduct surveys of the purported site of SS Federal, to provide positive identification of the site and ensure its protection in future. This will be supplemented by opportunistic deployments of the drop camera (supported by SIT) in the event that the shipwreck is located. The location of shipwreck SS Federal was reported to Heritage Victoria by sport divers in 2012. Unfortunately, the provided coordinates were insufficient to narrow down the location. Subsequent attempts to communicate with the finders have been unsuccessful. Accurate location of SS Federal is a priority for Heritage Victoria as they believe the finders wilfully misrepresented the data and may still be diving it, and potentially removing objects, in defiance of relevant heritage shipwreck protective legislation. Activities may also include opportunistic survey of three ‘unidentified targets’ located between the AHO mapping area and the search area for SS Federal. Aims are to positively identify these sites as cultural heritage targets (shipwrecks) via GSM and drop camera investigation, if time allows. 3) Training of Marine National Facility Operations and Support Team personnel in several routine and new underway and deployed systems, including: • Multibeam patch test calibrations and backscatter calibration lines. • Commissioning and trialling of new Brenke sled, Seaspy magnetometer (ahead of IN2019_V04) and RapidCAST SVP. • Triaxus, CTD casts, multicorer, Smith Mac grab. 4) Seabird and marine mammal observations (Dr Eric Woehler, University of Tasmania): This project will collect data to quantify the variability in the distribution and abundance of seabirds in the marine environment around Australia. The project will examine the relationships between physical oceanographic features and their use as seabird feeding areas. The study also seeks to identify species assemblages, or associations, in the species of seabirds observed that are persistent over time. The project will collect new data for seabirds around Australia, for which there are very few (and in many cases, nil) data. The project will use standard survey methods to ensure compatibility with existing data sets for the same species in other areas. Observations of marine mammals will also be shared with researchers to facilitate greater understanding of the role of oceanographic processes in the spatial and temporal distribution of marine mammals at sea around Australia. The project will also provide a context to current research efforts tracking seabirds and marine mammals, which are often constrained to a relatively low number of instrumented individuals relative to the population as a whole.” See EM122 metadata record at Marlin_EM122 See EM710 metadata record at Marlin_EM710 This dataset is published with the permission of CSIRO.

Boags Commonwealth Marine Reserve Bathymetry 1m (CSIRO) bf2018_v01 (AusSeabed:Boags Commonwealth Marine Reserve Bathymetry 1m (CSIRO) bf2018_v01)

The collection describes a final CSIRO L3 bathymetry products as gridded 1 metre resolution 32-bit floating point geotiffs. The voyage title, 'Hydrographic survey of the Petuna Aquaculture Sites in SW Bass Strait' departed Stanley, Tasmania on the 27th June 2018 and returned to Beauty Point, Tasmania on the 4th July 2018. This survey was a part of a broader mapping campaign that involved a survey of the Boags Commonwealth Marine Reserve. The processed bathymetry data was collected on MV Bluefin Voyage BF2018_V01 with multibeam single head system Kongsberg EM2040c providing a 1.3° by 1.3° beamwidth transmit and receive angular resolution respectively. A long CW pulse was used in the deeper water areas (Boags) and a Medium CW was used in the shallower water sites (Hope Channel & SE Hummock). The bathymetry data were acquiring using Kongsberg’s SIS (Seafloor Information System) software. The echosounder's nominal frequency was 300 kHz and was operated in dual swath mode. Tide corrections were not applied to the final processed dataset. Instead the data was mapped to the ellipsoid (GPS Height) and thereafter reduced to AHD (Australian Height Datum) using the AusGeoid09 model. Processed data has had outliers removed. Auxiliary sensors included an Applanix POS MV for position and motion information (aided with a Fugro Marinestar GNSS G2 subscription signal), a Valeport MiniSVS for sound velocity at the transducer and a Valeport MiniSVP (S/N 34826) for water column sound velocity profiles.

Great Australian Bight Bathymetry 20m - 100m (CSIRO) in2015_c01 (AusSeabed:Great Australian Bight Bathymetry 20m - 100m (CSIRO) in2015_c01)

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_C01, titled 'GAB deep water geological and benthic ecology program' which departed Hobart on the 25 October and returned to Port Lincoln on the 28 November. The Great Australian Bight (GAB) represents one of Australia’s most prospective frontier hydrocarbon exploration regions. However, the primary Ceduna sedimentary sub-basin – the focus of our work - is characterised by a paucity of data on its deep water geology and almost no knowledge of its benthic biological communities. The GAB was divided up into 15 sites that were mapped with the EK60, EM122, SBP120 and a magnetometer. That resulting data was used to decide on a sampling regime that attempted to fulfil the scientific outcomes See EM122 metadata record at Marlin_EM122 See EM710 metadata record at Marlin_EM710 This dataset is published with the permission of CSIRO. Not to be used for navigational purposes. We acknowledge the use of the CSIRO Marine National Facility, grid.473585.8 in undertaking this research.

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2017_C01, titled 'GAB deep water geological and benthic ecology program' which departed Hobart on the 11 April 2017 and returned to Hobart on the 28 April 2017. The voyage objectives were built around three main scientific objectives: The benthic characterisation and sampling outcropping sedimentary rocks to aid understanding of modern seabed erosional mechanisms, sedimentary processes and paleo-environmental reconstruction. Benthic characterisation and sampling in areas of potential seepage to determine if fluid escape is occurring and the nature of the fluids and their relationship to the benthic fauna in these areas. Sampling of benthic fauna over a large geographic area to establish deep water community structure and function and augment understandings gained from recent IN2015_c01 and IN2015_c02 voyages. Timely results from sea floor mapping were integral in supply updated bathymetry, backscatter, water column and sub-bottom profiler data to the science party to assist in determining ideal sampling locations for beam trawls, camera tows, rock dredges, CTD casts and grabs.

South Pacific Ocean Bathymetry 5m - 50m (CSIRO) in2019_v05 (AusSeabed:South Pacific Ocean Bathymetry 5m - 50m (CSIRO) in2019_v05)

The East Australian Current (EAC) is a complex and highly energetic western boundary system of the South Pacific Ocean off eastern Australia. It closes the South Pacific subtropical gyre, transporting heat, salt and plankton southward and onto the continental shelf. Off Brisbane (27oS) the EAC is north of the high eddy variability region, approaches its maximum strength and is relatively uniform and coherent. The mooring array is located near the existing long-term XBT transect and satellite altimetry ground tracks. The aim of this observing system is to capture the mean and time-varying flow of the EAC. This EAC mooring array is a component of IMOS. These observations will provide an intensive reference set of measurements of the EAC over a sustained period for improved understanding of the relationship of EAC with the basin-scale South Pacific gyre. The mooring array will provide a physical context for the impact of the EAC on upwelling and coastal marine ecosystems; on cross-shelf flows such as frontal eddies; and on the validation and interpretation of the EAC system in numerous climate and ocean models.

The Collaborative Australian Postgraduate Sea Training Alliance Network (CAPSTAN) is a post-graduate at sea training initiative on the RV Investigator. Governed by a network of leading industry and university partners from within marine science and geoscience, CAPSTAN is a first of its kind programme which will transform the way marine science education is delivered. A truly national education initiative, CAPSTAN offers a national approach to teaching and learning in the marine sciences whilst providing a platform for institutional, industrial and generational knowledge transfer and collaboration. Our aims have arisen out of a national desire to: • Develop an effective, efficient form of vessel‐based tertiary education by involving stakeholders and post-graduate students, and by pooling national tertiary teaching expertise and personnel resources; • Develop a national curriculum to standardise teaching protocols/methods and learning outcomes in this area in conjunction with the new data collection equipment and facilities of the Marine National Facility RV Investigator, the Integrated Marine Observatory System and external stakeholders, and; • Provide and test a multi‐disciplinary research‐based teaching module for marine science postgraduates with opportunities for student mobility and national network development.

AUSCPR_BIOMASS_INDEX (imos:AUSCPR_BIOMASS_INDEX)

IMOS - AusCPR: Biomass Index (mg/m3) The Australian Continuous Plankton Recorder (AusCPR) survey is a joint project between CSIRO Oceans and Atmosphere (O&A) and the Australian Antarctic Division (AAD) to measure plankton communities as a guide to the health of Australia's oceans. The biomass is analysed from the same segment from which the zooplankton is analysed. All the plankton is washed onto a pre-weighed filter. This is left in an oven at 60 degrees C for 24-48 hours. It is reweighed to give the dry weight. It is advised that anyone using the data should contact the project contact person. The aims of the AusCPR survey are to: * map plankton biodiversity and distribution * develop the first long-term plankton baseline for Australian waters * document plankton changes in response to climate change * provide indices for fisheries management * detect harmful algal blooms * validate satellite remote sensing * initialise and test ecosystem models. Servicing and maintenance of the CPRs and analysis of the samples for the AusCPR survey will be carried out by staff based at the O&A CSIRO laboratories in Queensland and Hobart and at the AAD in Hobart. The project was funded by the Integrated Marine Observing System (IMOS) and falls with the Ships of Opportunity facility. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Results from the AusCPR survey are available through the AODN portal: https://portal.aodn.org.au. This data is freely available but please acknowledge all relevant parties, as detailed in acknowledgement section.

IMOS_ABD_DATA (imos:IMOS_ABD_DATA)

Zooplankton biomass data have been collected in Australian waters since the 1930s, yet most datasets have been unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate this dataset of marine zooplankton biomass from Australian waters, within the geographical extents of 0-60S, 100-160E. Many of these are small-scale datasets , when combined, they provide over 85 years of large-scale zooplankton community biomass data for Australian waters from 1932 to the present. The data have been standardised, erroneous data removed, and all metadata included. We have lodged this dataset with the Australian Ocean Data Network (http://imos.aodn.org.au/), allowing full public access. The Australian Zooplankton Biomass Database will be invaluable for global change studies, research assessing trophic level linkages, and for initialising and assessing biogeochemical and ecosystem models of lower marine trophic levels.

IMOS_ACD_DATA (imos:IMOS_ACD_DATA)

Chlorophyll a is the most commonly used indicator of phytoplankton biomass and is a proxy for primary productivity in the marine environment. It is relatively simple and cost effective to measure when compared to phytoplankton abundance and is thus routinely included in many surveys. Here we collate 173,333 records of chlorophyll a collected since 1965 from Australian waters gathered from researchers, from regular coastal monitoring surveys to long ocean voyages. This dataset concentrates on samples analysed using spectrophotometry, fluorometry and high performance liquid chromatography (HPLC). The Australian Chlorophyll a database is freely available through the Australian Ocean Data Network portal (http://imos.aodn.org.au/). These data can be used in isolation as an index of phytoplankton biomass or in combination with other data to provide insight into water quality, ecosystem state, and / or the relationships with other trophic levels such as zooplankton or fish.

The Australian Zooplankton Database (1938 onwards) - Data (imos:IMOS_AZD_DATA)

Zooplankton are the key trophic link between primary producers and fish in pelagic ecosystems. Historically, there are few zooplankton time series in Australia, with no datasets longer than two years prior to 2008. Here we compile 98,676 abundance records of more than 1,000 zooplankton taxa from unpublished research cruises, student projects, published literature and the recent Integrated Marine Observing System. This dataset covers the entire coastal and shelf region of Australia and dates back to 1938. Most records are for copepods, but there are also data for other taxa such as decapods, chaetognaths, thaliaceans, appendicularians and cladocerans. Metadata are provided for each record, including dates, coordinates and information on mesh size and sampling methods. To facilitate analysis across the multiple datasets, we have updated the species names according to the World Register of Marine Species (WoRMS; http://www.marinespecies.org/about.php) and converted units to abundance per m3. These data will be valuable for studies of biodiversity, biogeography, impacts of climate change and ecosystem health. We encourage researchers holding additional Australian zooplankton data to contact us and contribute their data to the dataset so we can periodically publish updates.

RV Investigator Voyage IN2020_V06 (mnf:IN2020_V06_VOYAGE)

The primary objectives of the voyage are to acquire passive seismological data that will enable us to: Characterise the 3-D structure of the oceanic crust and sub-crustal lithosphere along the Macquarie Ridge Complex (MRC) with novel lithospheric seismic imaging. This includes teleseismic receiver function analysis, teleseismic and ambient noise tomography, joint inversion of receiver functions and ambient noise dispersion, shear wave splitting analysis, autocorrelation analysis, and enhancing of regional and teleseismic wavefield through array seismology.Describe the structural, thermal, and compositional nature of the central MRC by applying a range of seismic imaging techniques to identify velocity anomalies in the crust and mantle. This is possible because 2-D or 3-D images of velocity anomalies in the crust and mantle may be interpreted as structural, thermal, or compositional variations. These seismological objectives will be addressed by PIs Tkalcic, Eakin, and Rawlinson following instrument and data recovery scheduled by the MNF in 2021. To achieve the above objectives, we will deploy ocean bottom seismometers (OBSs) around Macquarie Island, to be recovered in 2021. The primary marine geophysical objectives of the voyage are to: Define sites for OBS deployments in the vicinity of Macquarie Island using multibeam sonar and sub-bottom profiling data. Pending scheduled testing later this year, deployment parameters are tentatively in water depths =1000 m and on gentle seafloor slopes, ideally flat, but not to exceed 30°. Sediment cover is preferred over bare igneous rock for OBS deployment. Existing data around Macquarie Island are not of sufficient quality to define deployment sites.Characterise the neotectonics, structure, and stratigraphy of the active Australian-Pacific plate boundary in the vicinity of Macquarie Island using multibeam sonar (both bathymetry and backscatter), sub-bottom profiling, gravity, and magnetics data. These data will also provide critical baseline information for benthic habitat mapping. PIs Coffin and Stock will lead efforts to address these marine geophysical objectives.

RV Investigator Voyage IN2021_V01 (mnf:IN2021_V01_VOYAGE)

The primary objective of this voyage is to ensure the orderly development of the krill fishery in waters off Australia’s Antarctic Territory. This will be achieved by updating the biomass estimate of Antarctic krill, enabling a revision of the catch limit within CCAMLR Division 58.4.2-East in the Indian Ocean (IO) sector of the Southern Ocean. Commercial krill fishing in the IO sector recommenced in 2016/17 after a 25 year hiatus. The current krill catch limit in the region is based on surveys conducted 14 years ago. There has been no regular ecosystem monitoring to assess how the system may have changed since then.

RV Investigator Voyage IN2021_V03 (mnf:IN2021_V03_VOYAGE)

This voyage will recover and re-deploy an array of six full-depth current meter and property (temperature, salinity and pressure) moorings from the continental slope to the abyssal waters off Brisbane (27oS). The observing system is designed to capture the mean and time-varying flow of the EAC. In order to resolve interannual and decadal signals we aim to maintain multi-year deployments of the array. The data from the EAC mooring array and other oceanographic sampling are essential for understanding, at the regional to global scale, the role of boundary current in the climate system, and, at the local scale, simulating cross-shelf flows, upwelling, and frontal eddy formation. These local-scale processes have a fundamental impact on nutrient and phytoplankton concentrations and therefore far-reaching effects on annual fisheries productivity and coastal shark interactions along the eastern seaboard. We will undertake CTD casts, sampling salinity and 02, and numerous Triaxus and ship ADCP sections across the EAC mooring line and at several locations during the transit from Hobart to the mooring sites. Additionally, we aim to complete two oceanographic surveys: one in the Fraser Island area between 28oS and 26oS; and the other on and over the continental shelf in the vicinity of the North Stradbroke Island National Reference Station. These surveys will include bongo net tows and Triaxus/SADCP sections and will occur in between the mooring operations and at the completion of the mooring operations, as well as opportunistic sampling of jellyfish and salps over the side of the vessel when it is stationary using the extendable “pool scoop”. We aim to sample small scale, ephemeral frontal eddies flowing down from Fraser Island and shelf – continental slope boundary exchanges.  These observations will enable us to characterise the spatial and temporal variability of shelf water and plankton around the Stradbroke Island National Reference Station (NRS) mooring, and their connection to the offshore regions. We will also deploy numerous eXpendable Bathymetric Thermographs (XBTs) during the transit from Hobart north. We will also aim to perform Triaxus and bongo net tows during the northward transit at various locations, with top priority given to a location off the coast of Newcastle NSW (near 32.5oS) to supplement the IMOS mooring and HF radar installation at that location. We will also deploy a number of floats (core Argo and BCG-Argo) during the voyage. We will collect salinity and oxygen samples for calibration of the CTD salinity and oxygen sensors. Limited dissolved inorganic carbon samples may be collected if we deploy BGC Argo floats). The following specific objectives will be completed: Moorings recovery and deployment at appropriate locations; Full depth CTD/rosette stations at each mooring recovery location with only salt and O2 water samples; Pre-deployment CTD casts for calibration of Seabird 37 and 39 mooring instruments to a depth of 2000 m; Triaxus and Ship ADCP sections at various locations during the transit from Hobart to the mooring locations, across the mooring line, at the shelf-slope and Fraser Island survey regions; Bongo net tows along the EAC mooring line, and as part of the shelf-slope and Fraser Island survey areas to study the significance of re-circulation features; Bongo nets, CTD and bio-acoustic samplings at various locations during the transit from Hobart to the mooring sites; and surrounding the Stradbroke NRS site including opportunistic sampling of frontal eddies; and Deploy Surface Velocity Program drifters, XBTs and Argo (core and BGC) floats during the voyage, with supporting CTDs in the case of BGC Argo floats.

KeyEcologicalFeatures (local:KeyEcologicalFeatures)

The Bioregional Profile identifies a number of ecological features that are of conservation value because of the role they play in the environment of the South-west Marine Region. Key ecological features meet one or more of the following criteria: 1. a species, group of species, or a community with a regionally important ecological role (e.g. a predator, prey that affects a large biomass or number of other marine species); 2. a species, group of species, or a community that is nationally or regionally important for biodiversity; 3. an area or habitat that is nationally or regionally important for: a) enhanced or high productivity (such as predictable upwellings - an upwelling occurs when cold nutrient-rich waters from the bottom of the ocean rise to the surface); b) aggregations of marine life (such as feeding, resting, breeding or nursery areas); c) biodiversity and endemism (species which only occur in a specific area); or 4. a unique seafloor feature, with known or presumed ecological properties of regional significance. Key ecological features have been identified by the Australian Government on the basis of advice from scientists about the ecological processes and characteristics of the area. A workshop held in Perth in September 2006 also contributed to this scientific advice and helped to underpin the identification of key ecological features. Sixteen KEFs have been identified in the South-west Marine Region: 1. Commonwealth marine environment surrounding the Houtman Abrolhos Islands 2. Perth Canyon and adjacent shelf break, and other west coast canyons 3. Commonwealth marine environment within and adjacent to the west coast inshore lagoons 4. Commonwealth marine environment within and adjacent to Geographe Bay 5. Cape Mentelle upwelling 6. Naturaliste Plateau 7. Diamantina Fracture Zone 8. Albany Canyons group and adjacent shelf break 9. Commonwealth marine environment surrounding the Recherche Archipelago 10. Ancient coastline at 90-120 m depth 11. Kangaroo Island Pool, canyons and adjacent shelf break, and Eyre Peninsula upwellings. 12. Meso-scale eddies (points). 13. Western demersal slope and associated fish communities. 14. Western rock lobster. 15. Benthic invertebrate communities of the eastern Great Australian Bight. No spatial representation available. 16. Small pelagic fish of the South-west Marine Region. No spatial representation available. In order to create a spatial representation of KEFs for the South-west Marine Region, some interpretation of the information was required. DSEWPaC has made every effort to use the best available spatial information, and best judgement on how to spatially represent the features based on the scientific advice provided. This does not preclude others from making their own interpretation of available information.

IMOS National Reference Station (NRS) - Zooplankton Biomass (imos:PLANKTON_NRS_BIOMASS)

Regular monthly zooplankton samples are undertaken at the stations as part of a larger water sampling program by the Australian National Reference Stations. In total nine stations are sampled regularly around the Australian coastline. Sampling is conducted monthly (Esperance and Ningaloo 3 monthly) off small vessels at each of the nine reference stations. The sampling is conducted using a drop net (as per the design of Heron) which has a 60 cm diameter, 100 micron mesh and is weighted to fall at 1 m/s. The net is designed to pull closed at the end of its fall so that it samples on the way down and does not sample on the way up. The depth of the sample varies at each station. 3 zooplankton samples are taken each month. 2 are fixed in formalin and will be analysed as described below. The unfixed sample is concentrated and frozen (-80oC)and will be used for molecular analysis in the future. The Port Hacking 4 (PH4) samples (2002 - Jan 2009) were sampled using a smaller net, 20 cm diameter, which sampled on the way up and down. The PH4 site is very close to the Port Hacking national reference station (PHB) where samples are now taken to build up and enhance the time series. The plankton ecology lab (based in Queensland) will analyse the samples collected for: 1. Community composition (Taxon/m3) 2. Biomass (dry weight in mg/m3) 3. Size spectrum analysis using zooscan (in progress) Data storage and access is planned to be interoperable with other national and international programs through the IMOS eMarine Information Infrastructure (eMII). Station metadata can be found through this resource. Further information is available from: http://www.marine.csiro.au/marq/edd_search.Browse_Citation?txtSession=8545

IMOS National Reference Station (NRS) - Phytoplankton Abundance and Biovolume (imos:PLANKTON_NRS_PHYTOPLANKTON)

This dataset comprises the phytoplankton abundance and biovolume estimates of a broader sampling program carried out by the Plankton National Reference Station within the Integrated Marine Observing system. Regular monthly phytoplankton samples are undertaken at the stations as part of a larger water sampling program by the Australian National Reference Stations. In total nine stations are sampled regularly around the Australian coastline. Sampling is conducted monthly (Esperance and Ningaloo 3 monthly) off small vessels at each of the nine reference stations. The sampling is an integrated water sample collected with niskin bottles at 10m depth intervals and preserved in lugols solution. The depth of the sample varies at each station. The plankton ecology lab (based in Queensland) will analyse the samples collected for: 1. Community composition / abundance (cells/l) 2. Biovolume (ml/l). Data storage and access is planned to be interoperable with other national and international programs through the IMOS eMarine Information Infrastructure (eMII). Station metadata can be found through this resource. Data is available freely via the IMOS data portal: http://imos.aodn.org.au/ As the taxonomic resolution of the data has changed over time, due to continual training, it is important that users refer to the change log tables included in your data download. These will provide information on the validity of the taxa, from what date we have been identifing certain taxa etc. Classification fields may be blank depending on the level to which that taxa has been identified, i.e. if only identified to family, genus and species will be blank.

Southern Ocean Time Series (SOTS) - Phytoplankton Abundance and Biovolume (imos:PLANKTON_SOTS_PHYTOPLANKTON)

This dataset comprises the phytoplankton abundance and biovolume estimates as part of a broader sampling program carried out at the Southern Ocean Time Series, a facility within the Integrated Marine Observing System (IMOS). The primary focus is sustained observing of ocean properties and processes important to climate, carbon cycling, and ocean productivity. Regular phytoplankton samples are collected at approximately 14 day intervals (exact intervals and seasonal coverage dependent on deployment length). The moorings are serviced annually, at which time the existing moorings are recovered and new moorings are deployed. Water samples from within the surface mixed-layer are collected at pre-programmed intervals using a Remote Access Sampler, in pairs about 1 hour apart. One sample in each pair is preserved for phytoplankton community composition by microscopy, and the other sample is preserved and used for accompanying chemical analysis of nutrients, total dissolved inorganic carbon (DIC) and alkalinity. Each sample is collected from within the surface mixed-layer at 32 m depth (2010 - 2017) or 5 m depth (2018-current) depending on the design of the mooring surface assembly and instrumentation. Typically a maximum of 24 samples are collected over an annual deployment cycle. The samples collected are analysed for: 1. Community composition / abundance (cells/L) 2. calculated biovolume (um3/L). Protocols for the phytoplankton time-series are described in Eriksen et al (2018), and the annual sample reports for each deployment. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is available freely via the AODN portal: https://portal.aodn.org.au. As the taxonomic resolution of the data has changed over time, due to continual training, it is important that users refer to the change log tables included in your data download. These will provide information on the validity of the taxa, from what date we have been identifying certain taxa etc. Classification fields may be blank depending on the level to which that taxa has been identified, i.e. if only identified to family, genus and species will be blank.

FR 08/99 (mnf:FR199908_VOYAGE)

The Carpentaria electrical conductivity anomaly is a major geological shear zone extending over a thousand kilometres in an approximately north-south orientation in northern Queensland. It has been mapped on land by various geomagnetic and magnetotelluric arrays, but the relationship between the conductivity anomaly and major tectonic boundaries is not straightforward. The offshore extent of the anomaly is unknown and poorly constrained by land measurements around the Gulf. The scientific objectives are therefore to: 1. Map the location of the Carpentaria anomaly and examine its spatial relationship with the tectonic structures in the region. 2. To determine the depth and length of the anomaly into the Gulf, and hence better understand the causes of high electrical conductance within the crust. 3. To relate the electrical properties to the tectonic evolution of northern Australia.

Assist with the development of ship inductions for visitors and voyage participants so that these are ready for arrival in Hobart. 12. Familiarisation with the layout of the vessel. The key to planning safe and efficient operations and voyages is knowing the ship and how it works. The ops team will be responsible for training tour guides for WTP and for introducing MNF support staff to the vessel from arrival in Hobart. There are also areas in the Voyage Manuals and Documents that have been unable to be completed as the team is not familiar with the layout of the accommodation and recreation areas and the laboratories and science areas. 13. Laboratories and science areas. The ops team have already begun planning and preparation for the sea trials and trial voyages out of Hobart. Familiarisation and testing to be able to advise potential trial voyage participants on equipment setup, location or facilities without ever having seen the ship. 14. Fairing the towed body cable. The end few hundred metres of the towed body cable requires fairing to be fitted before the sea trials. The workshop has sent the required equipment to the ship and the Ops team members have agreed to spend a few hours each day taking turns at the task. 15. Confirm container loading plan. 16. Assess the options for makeup air and exhaust management for the radioisotope container. 17. MNF Support staff groups (Electronics, Data Processing, GSM) will all be undertaking setup, testing and familiarisation of systems and equipment during the delivery voyage.

RV Investigator Voyage IN2015_C01 (mnf:IN2015_C01_VOYAGE)

RV Investigator Research Charter Voyage in2015_c01. GAB deep water geological and benthic ecology program. Scientific objectives: The Great Australian Bight (GAB) represents one of Australia's most prospective frontier hydrocarbon exploration regions. However, the primary Ceduna sedimentary sub-basin - the focus of our work - is characterised by a paucity of data on its deep water geology and almost no knowledge of its benthic biological communities. The Ceduna sub-basin is the product of rifting followed by the subsequent Southern Ocean seafloor spreading between Australia and Antarctica. The rifting created a narrow seaway between Australia and Antarctica, which was initially filled by two large deltaic super sequences (represented by the Tiger and Hammerhead super sequences respectively). Decreased sediment supply followed this period, during which commencement of fast seafloor spreading led to the initiation of widespread igneous activity and the development of a large number of volcanoes across the basin. Subsequent low sedimentation rates combined with continued subsidence have created the current modern deep water Ceduna sub-basin geomorphology. Key knowledge gaps in the understanding of the fundamental geology of the Ceduna sub-basin include: 1. Sedimentary facies and source rocks. 2. Hydrocarbon seeps. 3. Mid-Eocene Volcanic activity. 4. Basin and benthic biodiversity and distribution. The voyage objectives are built around three main survey targets: * Outcrops of sedimentary rocks - to collect samples for sedimentary facies and source rock analysis * Potential areas of seepage - to determine if hydrocarbon seepage can be identified * Deepwater seamounts - to identify, sample and investigate the nature of the mid-Eocene volcanics.

RV Investigator Voyage IN2015_C02 (mnf:IN2015_C02_VOYAGE)

RV Investigator Research Charter Voyage in2015_c02. Great Australian Bight (GAB) Deep water pelagic and benthic ecosystem study. Scientific Objectives: This voyage will characterise deep-water pelagic and benthic community structure and identify key ecological processes in the central and eastern GAB, and forms part of the GAB Research Program that aims to describe the key elements of the GAB marine ecosystem. This understanding of the structure and function of the ecosystem will be used to inform future integrated and sustainable ocean management and assessment/mitigation of potential future impacts. An overarching objective of the voyage is to contribute to developing models of ecosystem-level structure and function for the GAB The pelagic ecosystem structure in the eastern GAB, which is characterised by seasonal upwelling and a narrower continental slope, will be compared with the poorly sampled central GAB, where year-round downwelling is predicted and the shelf and slope are wider with the following GAB Research Program objectives; 1.Compare the eastern and central GAB continental margin zooplankton and micronekton communities in terms of their species composition, size range, biomass, nutrient source/trophic pathways and habitat. 2.Testing the hypothesis that the “microbial food web” is the dominant planktonic food web over the deep GAB continental margin, particularly in the central GAB where year-round downwelling is thought to be the prevailing cross-margin flow, and that the more efficient “classic food web” only dominates in the eastern GAB during periods of nutrient-rich upwelling. 3.Describing the community structure, dynamics, biodiversity and endemism of microbes (i.e., viruses and bacteria), plankton (i.e., phytoplankton, zooplankton, ichthyoplankton) and micronekton (including squids, small pelagic and mesopelagic fish and gelatinous organisms). Benthic characterisation is important because there are virtually no existing benthic biological data beyond continental shelf depths (<200 m); because conservation values attributed to Commonwealth Marine Reserves (CMR) spanning wide depth ranges are untested on the mid- and lower continental slope; and because oil and gas lease areas extend across the GAB Marine Park (GAB MP). Within the GAB Research Program, the Benthic Biodiversity project has the following objectives: 1.Quantify spatial patterns in the physical environment, and composition and abundance of benthic fauna in BP leases and adjacent continental slope areas of the Great Australian Bight (GAB) to provide baseline metrics relevant to monitoring the potential future impacts of oil and gas exploration on benthic communities. 2.Determine requirements (including identifying indicators and metrics), and identify suitable control sites, for future ecological monitoring in the GAB – especially to detect and quantify ecological impacts from oil and gas exploration on benthic communities of the GAB Marine Park.

RV Investigator Voyage IN2015_V01 (mnf:IN2015_V01_VOYAGE)

MNF RV Investigator Research Voyage IN2015_v01. IMOS Southern Ocean Time Series(SOTS) Automated Moorings for Climate and Carbon Cycle Studies Southwest Of Tasmania. Scientific objectives: The Southern Ocean has a predominant role in the movement of heat and carbon dioxide into the ocean interior moderating Earth's average surface climate. SOTS uses a set of three automated mooring to measure these processes under extreme conditions, where they are most intense and have been least studied. The atmosphere-ocean exchanges occur on many timescales, from daily insolation cycles to ocean basin decadal oscillations and thus high frequency observations sustained over many years are required. The current context of anthropogenic forcing of rapid climate change adds urgency to the work. Voyage objectives: The primary objective is to deploy a full set of SOTS moorings (SOFS, Pulse, and SAZ) and to obtain ancillary information of the oceanographic conditions at the time of deployment using CTD casts, underway measurements, the Triaxus towed body, and deployment of autonomous profiling Bio-Argo floats. Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges, with some redundancy: i) the Southern Ocean Flux Station (SOFS) focuses on air properties, ocean stratification, waves, and currents. ii) the Pulse biogeochemistry mooring focuses on processes important to biological CO2 consumption, including net community production from oxygen measurements and nitrate depletion, biomass concentrations from bio-optics and bio-acoustics, and collection of water samples for nutrient and plankton quantification. iii) the SAZ sediment trap mooring focuses on quantifying the transfer of carbon and other nutrients to the ocean interior by sinking particles, and collecting samples to investigate their ecological controls. Additional water sampling and sensor comparisons against shipboard systems provide quality control and spatial context, which is further augmented by Bio-Argo float and Triaxus towed body deployments, and satellite remote sensing. Please read voyage plan for full description.

RV Investigator Voyage IN2015_V02 (mnf:IN2015_V02_VOYAGE)

Investigator Voyage IN2015_V02 Title: Sustained monitoring of the East Australian Current: Mass, heat and freshwater transports. Scientific objectives The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia. It provides both the western boundary of the South Pacific gyre and the linking element between the Pacific and Indian Ocean gyres. This voyage will deploy an array of full-depth current meter and property (CTD) moorings from the continental slope to the abyssal waters off Brisbane (27o S). At this location the EAC, north of the high eddy variability, the EAC approaches its maximum strength and its flow is relatively uniform and coherent. The aim of this observing system is to capture the mean and time-varying flow of the EAC. This is a component of IMOS, and will provide an intensive reference set of measurements of the EAC flow over sustained period for monitoring EAC transport, improved understanding of relationship of EAC and the South Pacific gyre and impact of the coastal marine ecosystem, and validation and interpretation of the current system in numerous climate and ocean models. The mooring array is located on the existing long-term XBT transects, satellite altimetry and glider tracks. The EAC deep mooring array will be complemented by a Queensland- IMOS operated inshore mooring array on the continental shelf region. Voyage objectives This voyage will redeploy an array of six full-depth current meter and property (temperature, salinity and pressure) moorings from the continental slope to the abyssal waters off Brisbane (26o S). The observing system is designed to capture the mean and time-varying flow of the EAC. In order to resolve interannual and decadal signals we aim to maintain a multi-year deployment of the array. The main aim of the voyage will be to deploy an array of (6) full-depth current meter/CTD moorings extending from the continental slope to the abyssal waters off Brisbane. The following specific objectives will be performed: List of tasks 1. Carry out swath mapping from the abyssal plain to the base of the continental slope 2. Deploy each of the moorings at appropriate locations, including position triangulation of each mooring 3. Complete CTD/rosette stations at each mooring, with LADCP 4.

RV Investigator Voyage IN2015_V03 (mnf:IN2015_V03_VOYAGE)

Frontal eddies or “billows” are ubiquitous, small cyclonic eddies <100 km in diameter, and regularly characterise the continental side of all ocean boundary currents. They occur approximately weekly, and last up to 3 weeks which is sufficient for the early life history of fish. The physics and biology of these ubiquitous eddies are not understood. They are not resolved by present-day surface altimetry, but are evident along the East Australian Current (EAC) in SST or in real-time surface currents from the Coffs Harbour HF Radar (30.5°S). We will determine if uplift within the eddy nurtures plankton in comparison to the inner shelf water; and in comparison to similar eddies offshore around the EAC retroflection. We expect entrainment of adjacent shelf water is preconditioned to sustain larval fish, compared to entrainment of Tasman Sea water. We expect the condition and size distribution (survival) of larval fish will be greater in frontal eddies than in source water on the shelf or in the EAC. Frontal eddies may be a general mechanism for recruitment to coastal fisheries, such as for the Kuroshio Current, Gulf Stream, Agulhas Current. We will continue our long-term observations of phytoplankton, salps, krill, larval fish assemblages and eddy behaviour in this important region. We will investigate 2 to 3 frontal eddies on 2 separate occasions in the following possible locations: • the EAC separation zone south of North Stradbroke Island (27.6°S); or • south of Cape Byron (28.6°S); • south of Smoky Cape (30.9°S), • under the Coffs Harbour HF radar (30°S) • south of Seal Rocks/Sugarloaf Point (32.4°S) and off Port Stephens (32.7°S) or Sydney (34°S). Our scientific objectives are to: 1. Examine the entrainment shelf water and the amount of eddy uplift driven in relation to the strength of the adjacent EAC, coastal wind, the coastal counter-current, and slope canyons; and to quantify oceanographic behaviour of frontal eddies including their movement; 2. Compare the zooplankton size structure and the bioacoustic biomass between coastal waters, frontal eddies and the adjacent EAC or Tasman Sea; 3. Similarly compare the phytoplankton (prokaryotic and eukaryotic) biomass, diversity of pigments and other molecular markers and biogeochemical functions across coastal, EAC and frontal eddy water masses, 4. Similarly compare the zooplankton size structure and species diversity, the larval fish size distribution and the bioacoustic biomass; 5. The abundance, condition and genetic traits of other zooplankton (lobster phyllosoma).

RV Investigator Voyage IN2016_E01 (mnf:IN2016_E01_VOYAGE)

Scientific Objectives: 1) Dredge volcanic and sedimentary rocks to obtain new, rigorous age and paleo-depth constraints for the Cascade Seamount. Underway bathymetric data will be used to refine dredge targets. 2) Collect sediment cores across a depth transect to enable work investigating paleo-oceanographic conditions using proxies. Preferably at least a multicore proximal to IODP site 1172, and piston cores at the mid- and shallow-depth sites. 3) Collect high resolution swath bathymetry and sub-bottom profile data to see how far recent sediment flows extend from the Cascade Seamount towards IODP site 1172, to test the hypothesis that downslope transport resulted in the observed sediment patterns in core 1172. Existing coverage and resolution of bathymetry across the East Tasman Plateau is insufficient to resolve this question. 4) CTD to complement the sediment core data if possible. Alternative is for clean underway surface supply samples to be taken where CTD not possible.

RV Investigator Voyage IN2016_E02 (mnf:IN2016_E02_VOYAGE)

RV Investigator research voyage in2016_e02, titled “MNF Equipment Sea Trials.” The Primary objective of IN2016_E02 is to complete the sea trial regime as follows: • Demonstrate trawling equipment functions correctly, provide ASP crew training / exposure to trawling and confirm suitable manning levels for future trawling voyages, including emptying of scientific samples from a laden net; • Collect trawling data for analysis; • Deep towed camera system testing; • Demonstrate functionality of other equipment modified / upgraded / installed / maintained during the Sydney dry dock period; • Complete the installation of the UHDAS (ADCP) computer, and use the transit and trawling time for calibration, testing, and assessment and training on the new UHDAS software installation; • Transport the Investigator from Sydney to Hobart; • Deep water calibration of DECAF (Kloser charter).

RV Investigator Voyage IN2016_T01 (mnf:IN2016_T01_VOYAGE)

RV Investigator research voyage in2016_t01. Titled "Continuity of Australian terranes into Zealandia: towards a geological map of the east Gondwana margin." This is an extract from the Voyage Objectives in the Voyage Plan. We plan 4-6 dredges on the Fairway Ridge and Sandy Island area. The specific locations of potential dredge sites are shown on the voyage plan image and are tied to a confidential seismic reflection profile and/or swath bathymetry data. As we have access to high-resolution swath data from the area from the Geological Survey of New Caledonia, there is no necessity to plan a detailed swath survey for each dredge site. Swath bathymetry and ocean-bottom profiles (continuous collection) We will continuously collect bathymetric data and the North Loyalty Basin will be crossed during the transit voyage, thus requiring no additional time to collect this important swath profile. Gravity (continuous collection) We will continuously collect gravity data. There is no deviation necessary to obtain gravity measurements over the northwestern part of the Fairway Ridge as we will be crossing this area as part of the dredging component of the survey. CTD, hydrocast and bio-optical cast We will take two daily CTD profiles and hydrocast water samples to 500m to characterise the water at time of deployment for pigment, nutrient, dissolved oxygen, dissolved inorganic carbon and total alkalinity concentrations (up to 25 stations over the whole voyage). For this we will require the 36-bottle CTD rosette. Additional sensors to be included on the CTD frame include chlorophyll and CDOM fluorometers, absorption and backscattering meter, beam transmissometer, dissolved oxygen, deep SUNA and SeaFET pH. A Satlantic radiometer will be deployed separately at each station to a depth of 200m. We will be able to provide sensors that are not available through the MNF equipment pool (i.e. Satlantic SeaFET pH, Satlantic radiometer, Wetlabs acs and bb9, Hobilabs Hydroscat-6). Water samples will be filtered or chemically fixed on board according to standard operating procedures. We anticipate each deployment station taking 1.5 hours, with deployments taking place at the same time each morning and afternoon (nominally 0930 and 1400 hours), when not conflicting with dredge operations. Robotic Profiling Floats and bio-optics CSIRO will provide floats equipped with CTD and bio-optical sensors to measure a range of parameters: T, S, dissolved oxygen, chl and CDOM fluorescence, backscattering (4 wavelengths), beam attenuation, upwelling radiance and downwelling irradiance (4 wavelengths). Floats will be deployed at stations within Australian waters along the ship’s route of transit (estimate 155E and 160E). Deployment of the floats can be undertaken from the A-frame off the rear deck or by two people using a rope and manhandling the float over the stern. Once deployed, the floats will descend to depth and start their pre-programmed cycle of profiling and data collection, with data transmitted via Iridium satellites. During each deployment we will also take a CTD profile and water samples to 1000m to characterise the water at time of deployment for pigment, nutrient, dissolved oxygen, dissolved inorganic carbon and total alkalinity concentrations. Additional sensors to be included on the CTD include chlorophyll and CDOM fluorometers, backscattering meter and/or beam transmissometer, dissolved oxygen, deep SUNA and possibly SeaFET pH. We will seek to provide sensors that are not available through the MNF equipment pool (e.g. pH). Water samples will be filtered or chemically fixed on board according to standard operating procedures. We anticipate each deployment station taking 2-4 hours. Additional CTD and bio-optical casts will be taken twice per day (morning and afternoon, nominally 9.30am and 2pm) for bio-optical and biogeochemical sampling around the time of satellite overpasses. Full details available in the Voyage Plan.

RV Investigator Voyage IN2016_T02 (mnf:IN2016_T02_VOYAGE)

Voyage objectives The main objective of this transit voyage is to move the vessel from Hobart to Sydney prior to IN2016_V04. The objectives listed below are complementary with the transit. 1. Natural iron fertilisation of the oceans around Australia: linking terrestrial dust and bushfires to marine biogeochemistry Oceans play a vital role in Earth's climate through the control of atmospheric CO2. An important component of this system is the iron cycle, in which iron-rich aerosols are transported from land via atmosphere to ocean. Iron is a key micronutrient for marine phytoplankton, the scarcity of which controls essential biogeochemical processes. This project will facilitate an integrated ship-based atmospheric observational program for trace elements in oceans around Australia. During the voyages, we will sample and conduct experiments on atmospheric particles containing terrestrial dust, bushfire smoke and anthropogenic emissions that are transported from Australia to its surrounding oceans. This will provide the critical information on atmospheric iron supply for ocean fertility and health, providing the science for predicting a key factor in the future impact of the oceans on climate. The project supports the training and research of two postgraduate PhD students from IMAS-UTAS. 2. We will also opportunistically collect event-based clean rainwater samples using either a polyethylene funnel and collection bottle (when conditions allow) or a Dual Chimney Precipitation Sampler (N-Con Systems model 00-127; currently on order), to quantify the trace metal deposition in the 'bulk' and 'precipitate-only' fractions. Ideally samples would be collected on upper and forward decks, either above the bridge or at the bow when heading into the wind.

RV Investigator Voyage IN2016_T03 (mnf:IN2016_T03_VOYAGE)

Dry dock activities at Garden Island. The Primary objective of IN2016_T03 is to transit the Investigator to Sydney for dry dock activities & deploy 1 x Argo float. During the transit the following activities will be ongoing (1) Multibeam maintenance - 1 x Konsberg technician on board; (2) CTD Shaft removal preparations - 1 x Rapp technician on board. (3) One Argo Float will be deployed during transit from Brisbane to Sydney The following list details the key activities planned for 2016_T03 (Refer to section 4.2 for a detailed activity schedule): * Confirm all demobilization work is complete whilst alongside in Brisbane; * Confirm wires have been spooled off from the 2 x CTD winches, and spooling equipment is loaded onboard; * Depart Port of Brisbane with pilot on board; * Clear port limits and disembark pilot; * Transit to Argo deployment location & deploy 1 x Argo float; * Transit to Garden Island.

RV Investigator Voyage IN2016_V01 (mnf:IN2016_V01_VOYAGE)

HEOBI Heard Earth-Ocean-Biosphere Interactions RV Investigator voyage IN2016_v01. Voyage objectives: [1] Seafloor and subseafloor mapping/geophysical characterisation. Continuous mapping will be carried out using the multibeam systems, multi-frequency split-beam echosounders, sub-bottom profiler, gravimeter, and (on long transits between ports and the study area) magnetometer to characterise bathymetric features and identify those most likely to include volcanic or hydrothermal activity. XBT or CTD data will be acquired at standard intervals for sound velocity corrections to the multibeam data. The data will be initially processed at sea to inform site selection for volcanic and hydrothermal sampling. [2] Nature of submarine volcanoes and hydrothermal systems. We will characterise the spatial distribution, morphology, and geology of active submarine volcanoes and hydrothermal systems. [Extract only] [3] Detecting hydrothermal inputs to the ocean, and vertical water movements that deliver them to surface waters. …full-depth CTD/LADCP/TMR transects will be performed to capture cross-shore gradients in water. [Extract only] [4] Detecting impacts on surface phytoplankton production. During the underway mapping we will continuously operate sensors to measure biological activity (fluorescence for phytoplankton abundance, fast-repetition-rate fluorescence for phytoplankton photosynthetic competence, transmission for total carbon biomass, and O2/Ar ratio mass spectrometry for net community production). The sensors will be augmented by underway sampling for phytoplankton pigments, particulate organic and inorganic carbon, biogenic silica, heterotrophic bacterial responses, and microscopic phytoplankton identification to characterise community structures, and 15N measurements to identify the extent of nitrate versus ammonium metabolism – a key indicator of ecosystem Fe stimulation capable of additional carbon sequestration. Above and downstream of active hydrothermal systems, we will obtain samples for further analyses ashore. We also intend to carry out deckboard micro-nutrient enrichment incubation experiments to ascertain the biological response of hydrothermal iron to surface phytoplankton communities. Deployment of a bio-optical sensor package after each CTD deployment will provide measurements to link these communities to satellite images. [5] Ocean circulation around Heard Island and across the eastern Indian Ocean sector of the Southern Ocean. The shipboard ADCP and all available underway systems (thermosalinograph, meteorology, and biogeochemical systems) will be run at all times. We will seek contributions of autonomous instruments to deploy on the voyage to provide more detailed sampling of the circulation. We have contacted the Global Surface Drifter Program run by NOAA, and the Australian office of the International Argo Program. The lowered ADCP will be used at every CTD station to measure full water column velocity. New processing methods also allow the detection of internal waves and mixing using a shear-strain parameterisation, even in shallow waters. [Extract only] [6] Microbial response and bacterial processes What is the response of the microbial community to iron and organic carbon availability in different zones of the Southern Ocean, with focus on the possible impact of hydrothermal activity. More specific question: How does iron and carbon limitation affect heterotrophic bacterial respiration and growth efficiency, and its diversity? This text is an extract ONLY from the voyage plan. Please see in2016_v01 plan for full details.

RV Investigator Voyage IN2016_V02 (mnf:IN2016_V02_VOYAGE)

RV Investigator research voyage in2016_v02. Titled SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania. This voyage combines work from three projects. SOTS, CAPRICORN and Eddy Voyage objectives: SOTS The primary objective is to first deploy a reduced set (SAZ and FluxPulse) and then recover a full set of SOTS moorings (SOFS, Pulse, and SAZ). Additional work will obtain ancillary information on the atmospheric and oceanographic conditions using CTD casts, underway measurements, the Triaxus towed body, and autonomous profiling “Bio-Argo” floats. Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges, with some redundancy: • the SAZ sediment trap mooring focuses on quantifying the transfer of carbon and other nutrients to the ocean interior by sinking particles, and collecting samples to investigate their ecological controls • the Southern Ocean Flux Station (SOFS) focuses on air properties, ocean stratification, waves, and currents. • the Pulse biogeochemistry mooring focuses on processes important to biological CO2 consumption, including net community production from oxygen measurements and nitrate depletion, biomass concentrations from bio-optics and bio-acoustics, and collection of water samples for nutrient and plankton quantification. • the FluxPulse mooring combines some elements of Pulse onto the SOFS platform to create a combined mooring, which will be deployed for the first time in 2016. This combination meets financial constraints while still measuring almost all planned parameters CAPRICORN • The primary objective is to collect cloud, aerosol, precipitation, radiation and atmospheric composition measurements over the Southern Ocean over 30 days, and to capture the latitudinal variability of these properties from the latitude of Hobart down to 55-60S if time allows. The Investigator will be equipped with a state-of the art suite of instruments for that purpose (see list in voyage plan). • In order to address the "satellite validation" objectives, we need to locate the research vessel under the track of the CloudSat-CALIPSO instrument and within the larger swath of the NASA GPM and A-Train radars and radiometers. This will be achieved in coordination with the requirement to sample a mesoscale oceanic eddy using a dedicated pattern that will include satellite track following and mesoscale eddy sampling using radial transects, after the SOTS moorings are deployed and recovered. • In order to address the "ACCESS model validation" objectives, we need to sample the sub-grid scale variability of the atmospheric properties, therefore we will undertake some periods of intensive sampling of 12*12 km2 grids with small-scale lawnmower patterns, ensuring that the aerosol measurements are not perturbed by the ship exhaust. The timing and location of these grids will be determined during the voyage. Eddy • Deploy a suite of floats, two different models per eddy, to obtain profiles of temperature, salinity, velocity, oxygen, nitrate, pH and bio-optics near the eddy centre while we perform spatial surveys. • Measure the velocities and mixing in the two eddies. • Quantify the elemental fluxes associated with the eddy circulation, including nutrient transport and air-sea CO2 flux. • Measure the biological response to the circulation and nutrient transport, including primary productivity, trace metal biogeochemistry, new production and the respiration of downward carbon flux (using free-drifting sediment traps). Our combined ship-satellite-float observations will provide the most comprehensive view thus far of Southern Ocean eddies. Our work also contributes to emerging international programs in the Southern Ocean that are combining expanded autonomous observations with large scale modelling efforts. Full details are in the in2016_v02 voyage plan.

RV Investigator Voyage IN2016_V03 (mnf:IN2016_V03_VOYAGE)

RV Investigator research voyage in2016_v03. Titled Monitoring Ocean Change and Variability along 170oW from the ice edge to the equator This voyage involves two legs from Hobart to Wellington(NZ) and Wellington(NZ) to Lautoka(Fiji). Voyage objectives of the major project - Monitoring Ocean Change and Variability along 170oW from the ice edge to the equator are: The primary voyage objective is to obtain repeat occupations of the 155 full-depth CTD and Niskin casts along the GO-SHIP P15S section, with chemistry performed on water collected at 36 bottle levels. We will measure temperature, salinity, pressure, oxygen, fluorometry, shear and micro-scale temperature continuously, and the major nutrients, oxygen, salinity, CFC and carbon components discretely via chemical analysis on board. Small amounts of material will be filtered and stored for genomic analyses back on land. CSIRO has completed this line twice before and international groups have completed similar work along lines further east. The work plan and timings are based on these past voyages. Argo float deployments will also be carried out – usually when just leaving a CTD station (SOCCOM floats) or during transit (we may slow the ship speed slightly). These will be over the ship’s stern (preferred). Voyage objectives of the supplementary project -Facing the challenges of under-ice for autonomous navigation are: Accurate navigation under both drift and stationary ice is one of the key unanswered questions in polar marine science and engineering. The primary aims of this project are to (1) estimate INS drift and calibration times; and, (2) test the integration of acoustic positioning methods in an INS within a drifting and rotating frame of reference. This project will develop error propagation models at increasing latitudes and test the use of a non-stationary, ship borne acoustic positioning network on a small (<3 m) AUV. Both are critical for robust, accurate and reliable AUV operation under-ice. The primary voyage objective is make measurements of inertial drift during vessel transit and calibration time while the Investigator is on station across as broad a range of latitudes as possible. The way that this will be achieved is that, while the vessel is on station, bench top tests will be conducted for alignment. Then, while moving, tests of inertial drift will be conducted. The student on board will work with the other PIs on board to coordinate timings of these tests but will not disrupt the other work taking place on board. The work plan and timing is based on methodologies established during past voyages. Full details can be found in the in2016_v03 voyage plan. Previous MNF voyages include RV Franklin FR 05/2001 and RV Southern Surveyor SS200901.

RV Investigator Voyage IN2016_V04 (mnf:IN2016_V04_VOYAGE)

RV Investigator research voyage in2016_v04, titled "Influence of temperature and nutrient supply on the biogeochemical function and diversity of ocean microbes." Scientific Objectives: 1. Characterise the diversity and function of microbial communities in the relatively warm EAC, against the relatively cool water of the Tasman Sea and adjacent shelf waters. 2. Conduct perturbation experiments to experimentally test the role of temperature and nutrients (particularly N and Fe) in microbially mediated biogeochemical transformations. 3. Assess the links between microbial biomass, size structure and carbon production with higher trophic levels zooplankton, micronekton and cetaceansseabirds) in a frontal eddy(ies) relative to adjacent shelf and EAC waters. 4. Sample sediments to examine water-sediment geochemical processes and historical record of plankton. Previous sampling opportunities have not allowed us to revisit water masses (Aim 1) or conduct replicate experiments in the same water mass (Aim 2). Our objectives are therefore to more comprehensively sample the distribution and diversity of microbes across multiple oceanographic features. This includes cross-shelf transects, but also includes cross-eddy transects by extending shelf transects offshore (Aim 3). To achieve Aim 3, we will require real-time satellite information to identify our target area, as well as access to the IMOS ocean colour, SST, SSH data archive while on board. We will also conduct in situ 'mapping' of the target frontal eddy area using the Triaxus towed underwater body before we determine the exact location of transects and daytime CTD stations. Aim 3 activities will also involve bioacoustic monitoring in the western Tasman Front off Port Stephens, and within and outside of a frontal eddy. This will involve recording data from the EK60 of all 5 frequencies (if possible), which need to be appropriately coordinated with both ADCP. We suggest the two instruments should be programmed to ping and listen together, and to ignore any EK60 deeper than 750 to 1,000 m (to be confirmed with MNF and CSIRO bioacoustics group). Aims 1 and 2 relate to our original application for ship time and are hence the top priority. The Aim 3 activities occur mostly at night, which can be integrated into the day-time focussed sampling of Aims 1 and 2. Our intent is therefore to address these aims in waters north of Bass Strait (depending on the oceanographic features present). Activities to address Aim 4 have the lowest priority and are left to later in the voyage, but PIs have indicated that sediment cores from Port Hacking (NSW) will have strong scientific value for examining sediment fluxes and looking at the historic presence of microbial taxa.

RV Investigator Voyage IN2016_V05 (mnf:IN2016_V05_VOYAGE)

RV Investigator research voyage in2016_v05, titled “The Great Barrier Reef as a significant source of climatically relevant aerosol particles.” Voyage objectives The main objective of the voyage is to acquire observations that will address four key science questions about the role of atmospheric composition in the GBR region: 1. Do marine aerosols along the north Queensland coast have a significant signature that is coral derived? 2. How does this aerosol change its physicochemical properties, especially its capacity to act as CCN, as winds carry it from the reefs to the north Queensland rainforests? 3. What is the significance of this ecosystem as a source of aerosol particles and will potential degradation of the reef cause significant variations in particle number being generated over the reef. 4. Should changes in this aerosol, associated with reef degradation, be taken into account when modelling the radiative climate and rainfall? • Two stations on the western side of the GBR. These stations will enable us to sample the air masses that have traversed over the reefs and have been enriched by the emissions from the reefs. • One station on the eastern side of the GBR. As the predominant wind direction during the trade wind season is south easterlies this station will enable us to characterise the remote pacific air masses coming towards the GBR. • Optics station in deep water (>200m) east of Heron Island to characterise the sea surface spectral reflectance and in water optical properties including the spectral absorption of optically active constituents in the water. Supplementary Project: Biogeochemical and optical properties of the Coral Sea and Queensland Shelf Objectives 1. To collect high resolution biogeochemical observations for validation of the 4km and 1km near real time eReefs models (https://research.csiro.au/ereefs/) 2. To get modellers in the field to better understand methods and issues associated with modern methods of data collection 3. To collect in situ optical data for the NASA CORAL project which is operating a very high resolution airborne hyperspectral sensor along selected transects in the GBR. Piggy-back Project: Project 3DGBR - Multibeam bathymetry mapping of the Great Barrier Reef and Coral Sea Objectives: 1. To acquire high-resolution multibeam bathymetry, backscatter and water column data along the voyage track for the duration of the voyage. The new bathymetry data will be used to improve the accuracy of the 100 m-resolution DEM for the Great Barrier Reef and Coral Sea, called the ‘gbr100’ grid: http://www.deepreef.org/bathymetry/65-3dgbr-bathy.html 2. On an opportunity basis and subject to workload, acquire sub-bottom profile data using the SBP120 profiler during the voyage. The sub-bottom profiler data will be used in conjunction with the multibeam data for ongoing marine geoscience projects in the Great Barrier Reef and Coral Sea. For more information please refer to the Voyage Plan.

RV Investigator Voyage IN2016_V06 (mnf:IN2016_V06_VOYAGE)

RV Investigator research voyage in2016_v06, titled "Sustained monitoring of the EAC: mass, heat and freshwater transports." This voyage will recover and re-deploy an array of six full-depth current meter and property (temperature, salinity and pressure) moorings from the continental slope to the abyssal waters off Brisbane (27o S). The observing system is designed to capture the mean and time-varying flow of the EAC. In order to resolve interannual and decadal signals we aim to maintain a multi-year deployment of the array. The following specific objectives will be performed: 1. Recover and deploy moorings at appropriate locations. 2. Complete CTD/rosette stations at each mooring location, with LADCP. 3. Complete a number of Ship ADCP sections along the mooring line. Supplementary projects: 1) Turbulence scales and horizontal variability in the surface layer of the Ocean. Objectives: To gain more insight into turbulence scales in the upper ocean (0 - 200 m depth) across the continental shelf using a TuboMAP turbulence probe and to measure horizontal variability of CTD data in the upper ocean using a Seabird 19+ CTD unit. The TurboMAP can record data with vertical profiling (upcast and downcast). Based on a temperature gradient and mean falling speed of the probe the levels of turbulence dissipation and mixing properties can be derived. The CTD (Seabird 19+) unit will collect data at a fixed depth (ca. 20 m) while the ship is drifting at a speed of 0.5 - 1 m/s. 2) Spatial and temporal variability in the distribution and abundance of seabirds. Objectives: The project seeks to quantify the distribution and abundance of seabirds at sea using standardised seabird survey protocols. One or two dedicated observers will collect real-time data on seabirds observed within 300m transect during daylight hours while the vessel is underway. Incidental observations will be collected while the vessel is stationary (eg CTD stations) or while the vessel is deploying moorings. The data collected will be compatible with previous seabird at sea surveys conducted around Australia and farther south, allowing for analyses and assessments to be extended by the current surveys. The distribution of seabirds at sea is strongly linked with oceanographic features such as convergences that concentrate prey at densities that allow for efficient foraging by seabirds. Our surveys on the voyage will link with oceanographic investigations to identify the types and strengths of oceanographic features at which we observe different species of seabirds that utilise different methods of feeding (surface seizing, diving etc). No dedicated ship time is required for the seabird surveys. Surveys are conducted by observers while the vessel is underway during daylight hours.

2017 (2017)

RV Investigator Voyage IN2017_C01 (mnf:IN2017_C01_VOYAGE)

The voyage objectives are built around three main scientific objectives: • The benthic characterisation and sampling outcropping sedimentary rocks to aid understanding of modern seabed erosional mechanisms, sedimentary processes and paleoenvironmental reconstruction. • Benthic characterisation and sampling in areas of potential seepage to determine if fluid escape is occurring and the nature of the fluids and their relationship to the benthic fauna in these areas. • Sampling of benthic fauna over a large geographic area to establish deep water community structure and function and augment understandings gained from recent IN2015_C01 and IN2015_C02 voyages. Benthic characterisation of outcrop rocks and sampling of benthic fauna carry higher weight than that of the seep characterisation. The voyage plan includes more planned operations in each target area than can be achieved within the time allocations for the survey. Each of these target areas are ranked based on their importance in delivering on the scientific objectives. The survey will use a hierarchical design comprising seafloor mapping prior to seafloor sampling and limited water column characterisation. Seafloor mapping and water column characterisation 1. Hull mounted acoustic characterisation of the water column and seafloor over the target areas of interest. This activity will comprise the use of MBES, water column acoustic backscatter, single beam echo sounder, sub-bottom profiler and ADCP to determine processes occurring in the water column and map the seafloor and shallow subsurface geology. 2. Seafloor characterisation from the surface will be complemented with a limited number of tow camera to obtain video transects across the target area seafloor and overlying near bottom waters. Seafloor and water column sampling A number of sampling operations will be undertaken to describe the seafloor geology and benthic biota. Each sampling operation will differ dependant on sampling target, primarily based on substrate composition. For the soft substrate targets there will be a focus on grab samples whilst for the harder substrate types the focus will be on dredging. Sampling will be by: 1. Deployment of grab sampler to sample the surface sediment infauna, microbiology, hydrocarbon chemistry and physical properties. 2. Use of a beam trawl or Sherman sled to collect samples of benthic macro fauna over target areas. 3. Use of rock dredges to collects lithified sediments for description and detailed chemical analysis. 4. Limited collections of water column profile data including CTD, chemical sensor readings and associated water samples

RV Investigator Voyage IN2017_C02 (mnf:IN2017_C02_VOYAGE)

RV Investigator research voyage in2017_c02, titled "RAN Hydrographic Survey." Voyage objectives: to undertake hydrographic survey operations in the vicinity of Hogan Island (Bass Strait) to facilitate safe navigation for international and coastal shipping. The meteorological and oceanographic observations and data collection have three purposes, namely: a. To collect data from which a sonar or radar range prediction can be calculated (humidity, pressure, temperature, wind speed, ocean temperature and salinity profile, currents through depth, sediment type, sub-bottom classification, where possible). b. To identify what observations can be conducted concurrently, and what observations have limiting factors that preclude concurrent operations/survey activity. c. To develop understanding of what types, accuracy and formats of data can be collected and how this might be of use to the scientific community and Defence.

RV Investigator Voyage IN2017_T01 (mnf:IN2017_T01_VOYAGE)

The application will support research to quantify the importance of iron-rich aerosols from Australia for marine biogeochemistry and ocean ecosystem health. The project will sample and conduct experiments on atmospheric particles containing terrestrial dust and bushfire smoke that are transported from Australia to its surrounding oceans. The application supports the training and research of two postgraduate students from IMAS-UTAS.

RV Investigator Voyage IN2017_V02 (mnf:IN2017_V02_VOYAGE)

The Southern Ocean Time Series provides world-leading automated observations from deep-ocean moorings of the exchanges of heat, water, carbon dioxide, and oxygen between the ocean and atmosphere, and the physical and biological processes that control them. These results contribute to forward projections of anthropogenic climate warming, inform the setting of emissions targets, illuminate controls on climate variability, and provide a baseline for impacts on ocean pelagic ecology. Sensor data is returned live to the internet and samples are returned annually for further study in shore laboratories. The primary objective is to first deploy a new set of SOTS moorings (SAZ-19 and SOFS-6) and then recover the existing SOTS moorings (FluxPulse-1 lower section, and SAZ-18). Additional work will obtain ancillary information on atmospheric and oceanographic conditions using CTD casts, underway measurements, the Triaxus towed body, and autonomous profiling "Bio-Argo" floats. Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges, with some redundancy: * the SAZ sediment trap mooring collects samples to quantify the transfer of carbon and other nutrients to the ocean interior by sinking particles, and investigate their ecological controls. * the Southern Ocean Flux Station (SOFS) measures meteorological properties and ocean properties important to air-sea exchanges, ocean stratification, waves, and currents. * the (now superceded) Pulse biogeochemistry mooring focused on processes important to biological CO2 consumption, including net community production from oxygen measurements and nitrate depletion, biomass concentrations from bio-optics and bio-acoustics, and collection of water samples for nutrient and plankton quantification. * the FluxPulse mooring combines some elements of Pulse onto the SOFS platform to create a combined mooring, and was deployed for the first time in 2016, but broke into two sections. The top section has been recovered. The bottom section remains to be recovered. This combined mooring was intended to meet financial constraints. In 2017 we will use the simpler SOFS design, while redesigning FluxPulse for relaunch in 2018. Piggyback projects: * International Nutrient Intercalibration Exercise * Spatial and Temporal Variability in the Distribution and Abundance of Seabirds * Trace Element Cycling * Acoustic estimates of zooplankton and fish distributions

RV Investigator Voyage IN2017_V03 (mnf:IN2017_V03_VOYAGE)

RV Investigator research voyage in2017_v03, titled "Sampling the abyss: latitudinal biodiversity patterns along the base of Australia's eastern continental margin." The primary objective of this voyage is to sample the biodiversity of lower bathyal (2500 m) and abyssal (4000 m) seafloor habitats off south-eastern Australia, and in particular deep-water ecosystems of seven Commonwealth marine reserves. We will also sample a few shallower stations at 300 m (to trial the Brenke sled) and at 1000m (to ensure a supply of live animals). The depth and sites listed below are indicative only, and may change slightly based on topography and weather. To meet these objectives we will deploy a variety of gear to sample different components of biodiversity. The gear will also vary depending on the nature of the substratum (soft sediments or rock). The prime gear types include: 1. Beam trawl (O&A). This will only be used at sites with soft substrata 2. Heavy sled (Sherman) (MNF). This will only be used for sites that are determined to be hard ground from the multi-beam data. Sherman must be deployed off a stern trawl winch, which will require shifting of a trawl door (there will be plenty of time for this operation as all the soft-sediment gear will not be used at a rocky site). 3. Demersal trawl (NCRA) including floats (NCRA) & doors (Antarctic Division), the latter will be mounted on the stern near the trawl winches when not in use. Soft sediment only. 4. Brenke sled (MNF). Soft sediment or mixed soft-hard ground. It may require 2-3 floats to ensure it remains upright when deployed. It should be retrieved in an upright position using the A-Frame. A stand-alone CTD or camera can be mounted on the frame (see figure). 5. Biological box corer (MNF, previously belonging to Geoscience Australia) of dimensions 500 x 500 mm, sampling size 0.25 m2 (soft sediment only). If possible, this is best deployed on the side winch. 6. Deep-towed camera (MNF) with CTD 7. Surface plankton & mantra nets (O&A and MV), including depression plate and flow meter. In addition, we require multi-beam (Kongsberg EM122 & EM710) and sub bottom profiler for seafloor mapping, and echo sounders for bioacoustics (particularly the Simrad EK60). At each site, the procedure will be to first multi-beam the site to assess the distribution of rock and soft sediment habitats (if previous multi-beam data not available. This will guide the choice of gear and tow track. If the substratum contains mostly rock (possible for some 2500m sites), the heavy sled (Sherman) will be deployed. Otherwise a combination of beam trawl (with mounted camera), Brenke sled, demersal trawl and box core will be deployed. Box cores will be sub-sampled for sediment size and micro-plastics. For shallow water sites within CMRs, the deep-towed camera will be deployed instead of the box corer. The surface plankton net can be deployed during trawling (at appropriate slow ship speeds of under 2 knots). On this voyage there will be a particular emphasis on ensuring that the animals are collected and preserved in excellent condition for photographic and genetic analyses. Keeping the animals cold is the key. Consequently, the catch will be transferred to chilled water (5°C) as soon as it safe to approach the sampling gear. The animals will be sorted, identified and photographed in chilled water to prevent DNA degradation. The box cores will be elutriated (animals separated from mud) in chilled water also (at least for the upper 2 cm). This will require a user-supplied system to chill water in the vessel's walk in cool room. The bulk ethanol and formalin will be stored in the HazMat container, as will the 25L plastic drums full of preserved animals. For more information please refer to the voyage plan

RV Investigator Voyage IN2017_V04 (mnf:IN2017_V04_VOYAGE)

Zooplankton include the microscopic animals that link the ocean's single-celled algae and our fisheries, but it is a complex link. Huge changes in fish production may result from subtle changes in zooplankton production. The size distribution of zooplankton is a practical way to investigate this problem. This relatively simple size-based ecosystem will be integrated with the much larger sizes of krill, squid and pelagic fish. For the first time, the links between open ocean production and coastal fisheries of south eastern Australia will be established. This will inform environmental assessments and ecosystem sustainability, including the viability of super-trawlers in Australian waters.

RV Investigator Voyage IN2017_V05 (mnf:IN2017_V05_VOYAGE)

RV Investigator research voyage in2016_v05, titled “Long-term recovery of trawled marine communities 25 years after the world’s largest adaptive management experiment." The North West Shelf has seen massive reductions in trawling area and effort over past decades from the previous high levels of foreign trawling up until 1990. There remains debate about whether slow growing benthic organisms such as coral and sponges have recovered from this disturbance and whether the current management zoning which has been in place for 20 years and which includes areas closed to fishing, specific areas for trawling and trap is sustainable and effective. The outcomes of the study will have relevance to how trawl fishing is managed in Australia and internationally.

This survey will also improve confidence for subsurface navigation in Bass Strait. The overall focus for this survey is to conduct a modern survey in the primary shipping route through Bass Strait. The MET and OC observations and data collection have three purposes, namely: a) To collect data from which a sonar or radar range prediction can be calculated (humidity, pressure, temperature, wind speed, ocean temperature and salinity profile, currents through depth, sediment type, sub-bottom classification (where possible); - Sub-bottom classification will incorporate sediment samples taken using the MNF Smith-McIntyre Grab. Samples will be kept and stored with Geoscience Australia (GA). b) To identify what observations can be conducted concurrently, and what observations have limiting factors that preclude concurrent operations/survey activity; c) To develop understanding of what types, accuracy and formats of data can be collected and how this might be of use to the scientific community and Defence. A full GSM Survey Procedure pertaining to the hydrographic surveying elements of the primary voyage are included in appendix 1 – GSM Hydrographic Survey Procedure.

Harmful Algal Blooms And Their Long-Term Sediment Record In East Coast Tasmanian Waters (Chief Scientist: Gustaaf Hallegraeff, IMAS/UTAS) Unprecedented toxic dinoflagellate blooms occurred off east coast Tasmania in 2012 and 2015/2016. These events led to a global shellfish product recall (AUD23M loss), lengthy (4 months) closures of mussel, oyster, scallop, and rock lobster fisheries, and 4 human hospitalisations (Paralytic Shellfish Poisoning). While the causative Alexandrium dinoflagellate had been previously detected, genetic evidence suggests that blooms represent a cryptic genotype newly stimulated by climate-driven increased water column stratification. We seek to characterize blooms from with the long time (1000+ yr) ancient DNA sediment record using novel genetic methods.

RV Investigator Voyage IN2018_V01 (mnf:IN2018_V01_VOYAGE)

Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry (Chief Scientist: Dr Steve Rintoul, CSIRO) The Southern Ocean has a profound influence on regional and global climate, sea level rise, and biological productivity. The project aims to discover how and why the Southern Ocean is changing, and to identify the consequences of those changes for climate, sea level and marine life. The research will help deliver more reliable projections of future climate, from models that more faithfully represent critical Southern Ocean processes; such information is urgently needed to allow Australia to foresee and manage the risks and opportunities associated with climate change. CAPRICORN: clouds, aerosols, precipitation, radiation and atmospheric composition over the Southern Ocean (Lead Principal Investigator: Dr Alain Protat, BOM) Clouds over the Southern Ocean are one of the largest uncertainties in the prediction of the future climate of the Southern Hemisphere. This study will bridge an observational gap in this data-sparse, unique region of the World assisting in understanding why climate models poorly simulate the energy balance over the Southern Ocean and improving skill of weather forecast models to simulate frontal cloud systems. This will be achieved by analysing cloud, aerosol, and precipitation observations of frontal cloud systems and associated processes using dedicated radar, lidar, and radiosounding observations from the RV Investigator and satellite platforms.

Integrated Monitoring Observing System Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania (Chief Scientist: Professor Tom Trull, ACE-CRC) The Southern Ocean Time Series provides world-leading automated observations from deep-ocean moorings of the exchanges of heat, water, carbon dioxide, and oxygen between the ocean and atmosphere, and the physical and biological processes that control them. These results contribute to forward projections of anthropogenic climate warming, inform the setting of emissions targets, illuminate controls on climate variability, and provide a baseline for impacts on ocean pelagic ecology. Sensor data is returned live to the internet and samples are returned annually for further study in shore laboratories. Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site (Lead Principal Investigator: Professor Philip Boyd, UTAS) The Southern Ocean straddles the waters between Australia and Antarctica and has two distinct regions – the subantarctic and the polar seas. The latter is comprehensively studied by expeditions by Australia’s Antarctic Division, whereas the subantarctic has received much less attention. This voyage aims to determine processes within the subantarctic environment that control productivity, foodwebs and cycles of elements such as carbon. Enhanced understanding will maximise investments, such as in ocean time-series in subpolar waters and enable better predictions to be made on how marine life and chemistry are controlled by both natural and human-made shifts in climate and ocean conditions.

RV Investigator Voyage IN2018_V03 (mnf:IN2018_V03_VOYAGE)

Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South (Chief Scientist: Dr Bernadette Sloyan, CSIRO) The East Australian Current (EAC) is the complex and highly energetic western boundary current of the South Pacific Ocean. The EAC is the dominant mechanism for the redistribution of heat and freshwater between the ocean and atmosphere in the Australian region; it is a vital component of the eastern Australian coastal ecosystem. The monitoring of the EAC is central to our understanding of how climate variability is communicated through the global ocean. This ocean current time-series will provide significant insights into the interactions between the EAC, the Pacific basin and the local shelf ocean circulation.

RV Investigator Voyage IN2018_V04 (mnf:IN2018_V04_VOYAGE)

“RV Investigator research voyage in2016_v04, titled “Constraining external iron inputs and cycling in the southern extension of the East Australian Current.” The primary objective of the voyage is to characterise the sources and biogeochemical cycling of iron and associated nutrients and their impact on productivity southwest, southeast and northeast of Tasmania. This will require various deployments at a number of process and transit stations. Mesoscale and sub-mesoscale physics and biogeochemistry TRIAXUS: This will provide high-resolution real-time data acquisition on upper ocean (1-200 m) physics (mixed layer depth) and biology (chlorophyll fluorescence, transmissivity). We will survey each process station by conducting a transect across each station, ‘figure-eight’ type survey if possible for 10-12 hours, and tow the Triaxus between process stations 1, 2 and 3. These datasets will be complemented by those from underway sampling (including nutrient concentrations, biooptics, Fast Repetition Rate Fluorometry (FRRF, a measure of phytoplankton ‘health’), trace metal concentrations using a trace-metal clean tow-fish to sample at 5 m. SADCP/LADCP: Continuous measurements of velocity will be collected along the ships track using the 75 kHz and 150 kHz shipboard ADCPs. A lowered ADCP (LADCP) will collect horizontal velocity measurements at each station from the CTD package. Process and transit station deployments determine iron supply and cycling CTD rosette: Profiles of temperature, salinity, and oxygen through the upper ocean at transit stations and full ocean depth at process stations. Water samples collected with the 36-bottle rosette will be analysed on board for salinity, oxygen, nutrients. LADCP data will also be collected from the CTD deployments. TMR and ISP deployments: An autonomous 12 bottle trace metal-clean rosette (TMR) system and 6 in situ pumps (ISPs) will be used to collect trace element and isotope samples in dissolved and particulate phases. Clean sampling and analytical container laboratories will allow for shipboard processing, experiments and some near real-time analyses of iron at sea. The majority of the analyses will take place ashore after the voyage using sophisticated instrumentation not suited for shipboard use. In situ primary production: Primary production experiments will be conducted at each process station. The experiments will require radiolabeling samples with 55Fe and 14C in the Radiation van and then incubated in the deck-board incubators. Incubations: Some incubations may be conducted at each process station. The experiments will require the changes in light, nutrient and or trace metal conditions. Samples will then be incubated in the deck-board incubators or the ones in the dry lab. Multicorer deployment: Surface sediment cores (0 to 30 cm) will be collected on and off the Tasmanian shelf and at the three process stations. Cores will be evaluated for integrity upon recovery, sectioned inside a nitrogen-filled glove bag, and centrifuged to extract pore fluid for trace metal and rare-earth analysis. Kasten gravity corer: Longer sediment cores (0 to 4 m) will be collected at the three process stations. Cores will be evaluated for integrity upon recovery and subsampled for shore-based analyse. These will complement multicorer deployments. We hope to obtain one core at each of the process stations. Core barrels will 4 m in length.

RV Investigator research voyage in2018_v05, titled “How does a standing meander southeast of Tasmania brake the Antarctic Circumpolar Current?" The planet’s largest current, the Antarctic Circumpolar Current (ACC) distributes heat, freshwater and carbon-dioxide among the major oceans. It is a central element of the global overturning circulation that has allowed the ocean to absorb 93% of global warming. Despite Southern Ocean winds increasing for the last 2 decades, the ACC strength has not changed. A major puzzle in understanding climate variability is how the ACC responds to the additional wind energy. We will address the societally-important need to understand how the ACC and Southern Ocean’s capacity to absorb heat and carbon-dioxide will respond to climate variability and change. We will combine a full-depth CTD/LADCP and bathymetric survey of the full meander, with targeted, rapid underway sampling of smaller-scale variability using the Triaxus towed CTD, a VMP-2000 microstructure profiler and underway instruments. Multi-beam data will be important for interpreting the survey data. Water samples will be analysed for nutrients, chlorophyll and particulate organic carbon (POC). Incubation experiments will be conducted to observe phytoplankton productivity under varying physical and chemical conditions. Objectives 1. Deployment of a fleet of EM-APEX profiling floats. 2. Deployment of a tall mooring at the crest of a meander in the Polar Front of the Antarctic Circumpolar Current. 3. Full-depth hydrographic survey of the physics and biogeochemistry of the targeted ACC meander, conducting transects across the front. This will include CTD/LADCP profiles, water sample analysis, VMP-2000 microstructure profiles, bathymetry and underway instruments. 4. Triaxus transects. These will include transects across and along the front and transects around the mooring.

Status and recovery of deep-sea coral communities on seamounts in iconic Australian marine reserves (Chief Scientist: Dr Alan Williams, CSIRO) Australia has protected spectacular deep-sea coral reefs living on undersea mountains (‘seamounts’) by including some in marine reserves off Tasmania. This protection is an important step in marine conservation because deep-sea coral reefs support highly diverse communities of seafloor organisms, but are fragile and vulnerable to human disturbance – particularly by bottom trawling. Scientists on RV Investigator will conduct camera surveys to map the extent of the globally-significant deep-sea coral reefs, and determine how much of the reef area lies within reserves. Scientists will also measure how the reefs have recovered from earlier trawling impacts since being protected in marine reserves.

RV Investigator research voyage in2019_v01, titled "The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean." We will operate south of 60°S, northward of the ice edge, and between 140°E and 175°W. The specific study area/s within these boundaries will be determined by the locations of vocalising Antarctic blue whales, krill and sea-ice. The survey design is therefore adaptive in that sites will be chosen in real-time on the voyage according to available information. At the commencement of the voyage we will head straight to the closest group of vocalising Antarctic blue whales (ABWs) within our operational area. Vocalising ABWs are able to be detected through sonobuoys (see below) hundreds of kilometres away. When whales are found we will undertake a series of activities at that site. We will then commence a series of line transects in the same region and remain within the same area for the rest of the voyage. The study is therefore on a mesoscale and we do not aim to cover our entire operational area. The activities required to achieve our voyage objectives are: • Passive Acoustics • Whale observing, video-tracking and biopsy • Active Acoustics • Krill trawls • Unmanned Aerial Systems (UASs) • Biogeochemistry

RV Investigator research voyage in2019_v03, titled “A coupled bio-physical, ecosystem-scale, examination of Australia’s International Indian Ocean Expedition line.” The voyage will take place in the SE Indian Ocean along 110°E between 39°30’S and 11°30’S and, to meet the scientific objectives, a wide range of activities will be conducted. Essentially, on station activities can be classified into CTD deployments with associated water sampling, zooplankton sampling with a range of nets and profiling for optical properties and radiometry (Table 2). Several laboratory and on-deck incubation activities will be conducted and deployment of a Continuous Plankton Recorder, micro-zooplankton profiler, Vertical Microstructure Profiler VMP200, ARGO floats, surface drifters and sonobuoys will also take place. The Triaxus with instrumentation will be towed on the return leg back to Fremantle. CTD sampling and the vertical hauls with an Indian Ocean Standard Net (IOSN) are the priority tasks at all stations. After this, in the day time, the optical properties work will be a priority and, at night, plankton sampling with the various nets is the priority. When we were preparing this voyage plan it became apparent that the in-water optics deployments (PI Antoine; objective 4) would take much longer than originally expected. This would result in a considerable reduction of time available to transit between stations so much so that we would not be able to maintain the two stations per day that were done in the original 1960’s 110°E voyages. We subsequently prepared a revised voyage plan and each of the 20 stations on the 110°E line is now occupied for around 16 hours instead of 4 hours. For this voyage, on each station we now plan to complete a morning deep CTD (water for Thompson, Antoine, Ostrowski and Seymour teams) and vertical zooplankton haul with the Indian Ocean Standard Net. This will be followed by the optics measurements in the early afternoon and, in the evening, an EZ net tow, assorted plankton and neuston tows and a shallow CTD to obtain water for experiments and incubations (Raes and Landry). As there will be some time available in the afternoon after the optics measurements, we plan to conduct additional day-time EZ net and plankton tows, vertical microstructure profiling and other sampling that would benefit from day/night comparisons. The final temporal arrangement of these late afternoon activities will be subject to time availability, sea conditions and might change to maximize efficiency. However, the evening surface neuston tows must start promptly at 18:00. This revised plan has no difference from the original voyage proposal with respect to distance travelled by the ship. If we encounter bad weather along the 110°E line, we could wait until it clears using the two-day contingency period. However, if bad weather occurs at the southern-most stations along the 110°E line, the long-term marine weather forecast would have to be considered, as it may be wiser to proceed northwards and skip a station.

RV Investigator Voyage IN2019_V04 (mnf:IN2019_V04_VOYAGE)

In a handful of locations on Earth, hot material rises from deep within the Earth to create lines of volcanoes such as the Hawaiian-Emperor Seamount Chain. We aim to test if the Tasmantid and Lord Howe Seamount chains, hidden in the seas off eastern Australia, should be included in this rare group and if the Louisiade Plateau to the north could have formed from the massive flood of basaltic lava triggered when a rising plume reaches the surface.

RV Investigator Voyage IN2019_V05 (mnf:IN2019_V05_VOYAGE)

The East Australian Current (EAC) is the complex and highly energetic western boundary current of the South Pacific Ocean. The EAC is the dominant mechanism for the redistribution of heat and freshwater between the ocean and atmosphere in the Australian region; it is a vital component of the eastern Australian coastal ecosystem. The monitoring of the EAC is central to our understanding of how climate variability is communicated through the global ocean. This ocean current time-series will provide significant insights into the interactions between the EAC, the Pacific basin and the local shelf ocean circulation.

RV Investigator Voyage IN2019_V06 (mnf:IN2019_V06_VOYAGE)

Accurate predictions of Australia’s regional weather and climate require accurate representations of atmospheric and oceanic processes in our prediction models over the entire globe, and not just over Australia. However, some global locations are more important than others, and one is the region known as the ‘Maritime Continent’, comprising the islands and seas of Indonesia, Malaysia, New Guinea, and surrounds. This voyage will form part of a larger international effort to tackle the problems of the Maritime Continent in our models by making detailed observations of the daily cycles of convective storms and the mixing of heat in the atmosphere and ocean.

RV Investigator Voyage IN2020_T01 (mnf:IN2020_T01_VOYAGE)

The original scientific objectives of this voyage were cancelled due to the coronavirus crisis. The voyage proceeded as a purely transit voyage with minimal staff and operations on board.

RV Investigator Voyage IN2020_V01 (mnf:IN2020_V01_VOYAGE)

RV Investigator research voyage in2020_v01 is titled “Development of William’s Ridge, Kerguelen Plateau: tectonics, hotspot magmatism, microcontinents, and Australia’s Extended Continental Shelf.” The Indian Ocean contains numerous enigmatic topographic features, and some of the least understood are submarine ridges. This expedition will focus on William’s Ridge, part of Earth’s second largest submarine plateau, the Kerguelen Plateau, and on the once adjoining Broken Ridge. The voyage will acquire and analyse rock samples and geophysical data from these ridges to understand how they formed and evolved. The research will aim to resolve questions about the plate tectonics of the Indian Ocean, determine if William’s Ridge is a continental sliver, help understand massive volcanism triggered by mantle hotspots, and potentially contribute to expanding Australia’s sovereign undersea territory. The two principle scientific objectives of the voyage are: 1. To gain important new knowledge of the rifting, breakup, and initial separation of tectonic plates. The project constitutes the first-ever case study of conjugate oceanic plateau end-members – the formerly contiguous and subaerial, but now separated and submarine Kerguelen Plateau and Broken Ridge in the southern Indian Ocean – to investigate these phenomena. 2. To acquire, analyse, and interpret data and samples necessary for Australia to make a new or revised submission to the UN Commission on the Limits of the Continental Shelf (CLCS). The purpose is to extend our marine jurisdiction to include William’s Ridge, an extension of the Central Kerguelen Plateau, under the UN Convention on the Law of the Sea (UNCLOS). To address the scientific objectives of the project, the voyage objectives encompass acquiring and initially processing multibeam bathymetry/backscatter, water-column echo-sounding, sub-bottom profile, seismic reflection, deep-towed camera, gravity, and magnetic data acquisition; and acquiring rock samples by dredging. The acoustic data will be used to determine the locations of the seismic reflection profiles, and the acoustic and seismic data will be used to determine locations of dredging sites. The following activities will be undertaken: 1a. Multibeam bathymetry/backscatter: we will acquire multibeam data along William’s Ridge, the conjugate portion of Broken Ridge not covered by the MH370 search data, and associated seafloor topographic features. 1b. Sub-bottom profiling: we will acquire SBP120 data continuously multibeam data acquisition. 1c. Seismic reflection: we will utilise the MNF’s new seismic system, currently consisting of a 40-channel, 500-m-long, 12.5-m group spacing streamer and two GI airguns. 1d. Dredging: recovery of continental, hotspot-related, and/or oceanic rocks forming the basement of William’s Ridge and associated topographic features in the Labuan Basin, in multiple locations, is the goal, complemented by sampling the conjugate basement of Broken Ridge. 2a. Single-beam and multi-beam water column echo-sounding: we will collect EK60 and ME70 data throughout the entire voyage. 2b. Deep tow camera: on the basis of dredges and water column echo-sounding data, we will acquire still and video photography at locations characterized by mixed hotspot-related/oceanic/continental rocks and acoustic plumes emanating from the seafloor. 3a. Gravity: gravity data will be acquired by the shipboard gravity meter during the entire voyage. No modern shipboard gravity data have been acquired over William’s Ridge. 3b. Magnetics: we will acquire total magnetic field data using the towed proton precession magnetometer on the transits and throughout multibeam/sub-bottom profiling data acquisition. For more information about the voyage objectives and projects please refer to the voyage plan.

RV Investigator Voyage IN2020_V08 (mnf:IN2020_V08_VOYAGE)

Voyage objectives: 1) A modular 3.5 day cycle of diverse water column activities from deployment and recovery of surface tethered free floating moorings (RESPIRE, particle sediment traps), to deployment from the ship of CTD, profiling cameras, net tows, ISP’s, and water sampling to run lab based experiments. This cycle will be repeated 3 times at the subantarctic site (lower productivity and particle export) and 4 times at the polar site (bloom/bust and higher productivity and particle export). The mooring deployment / recovery is the most weather dependent event. Weather days will be factored in and may result in a modification of the number of cycles or their duration. In order to fully meet the multiple aims of the voyage we will carry out additional sampling (to add to our time series) on ‘weather days’ that we do not use for bad weather. 2) Land-based satellite oceanography will be linked to shipboard bio-optical and optical sampling for validation (within the 3.5 day cycle of 1) above). It will be further underpinned by the deployment of gliders (from collaborators at CALTEC, USA) – one at each site (recovered post voyage downstream off New Zealand by another vessel). Weather should be of little influence for these deployment activities across the 45 day voyage. 3) Deployment of two state-of-the-art BGC-ARGO profiling floats with miniaturised UVP (Underwater Vision Profiler) on a 5 year mission. The floats telemeter datasets and their output will be modelled by collaborators in Spain. If weather conditions permit we may attempt to retrieve each BGC-ARGO for a data download (using ‘Trull’ device – see equipment manifest for details). 4) SOLACE sits under the JETZON umbrella - http://jetzon.org/ . The site is currently being developed and we are already (in anticipation of our voyage) contributing to metadata development and modelling initiatives. 5) Conduct aerosol and rain sampling: a. ASP to provide advance notice of incineration events and a final record of incineration events for the voyage to both the aerosols and atmospheric teams. b. Require access to aerosol sampling lab. 6) Cosmic ray measurements from underway instrument (Dr Grahame Rosolen, CSIRO). 7) Cloud Aerosol Precipitation Radiation Interactions eXperiment (CAPRIX) (Dr Alain Protat, BOM). 8) Completion of noise signature testing (MNF). a. This will be completed in Storm Bay immediately following departure and will be structured so as not to impact science equipment testing in Storm Bay and the voyage schedule. 9) To complement the CTD casts and regular BGC Argo floats, underway instrumentation will be running and will require some estimate of the mixed layer depth to support these observations. To give subsurface temperature structure while the ship is in transit, deployment of 12 x XBTs to observe subsurface properties while the ship is in transit between the 2 sites will be undertaken. These deployments are not permitted occur within Australian Marine Parks (AMPs).

RV Investigator Voyage IN2020_V09 (mnf:IN2020_V09_VOYAGE)

This is the first research voyage since the MNF research schedule was suspended in March 2020 due to the COVID-19 pandemic. Consequently, this voyage will combine into a single voyage two research projects originally scheduled for separate voyages: Southern Ocean Time Series (SOTS) maintenance (Dr Elizabeth Shadwick, CSIRO): Deploy two new SOTS moorings (SOFS-9 and SAZ-22) and recover two existing ones (SOFS-8 and SAZ-21). These automated deep-water moorings measure the exchanges of heat, water, carbon dioxide and oxygen between the ocean and atmosphere, and the physical and biological processes that control them. Oceanographic mooring recovery (Dr Steve Rintoul, CSIRO): Recover an oceanographic mooring deployed during voyage IN2018_V05 to investigate Antarctic Circumpolar Current. This mooring has collected data to improve understanding of how Southern Ocean currents respond to changes in wind speed.

RV Investigator Voyage IN2020_V10 (mnf:IN2020_V10_VOYAGE)

Project 1: Complete trials and testing of MNF equipment Testing and trials of MNF and some non-MNF equipment (PLAOS) is to be completed during approximately 50% of the voyage. These trials are to optimise design and deployment characteristics and methods to ensure continued and optimal support of scientific objectives during the 20-21 Voyage Schedule. Project 2: RV Investigator Storm Bay Sampling for the FRDC Project ‘Storm Bay Modelling & Information System’ Intended to complete a targeted sampling program to characterise the deep water south of Storm Bay and its nutrient concentration, which is currently uncertain. Water samples and sensor data will assist in resolving whether deep water intrusions into Storm Bay have the potential to modify water quality. To achieve these objectives the project is 2 years into a 3.5 year program of hydrodynamic, sediment, optical and biogeochemical model developments and a targeted observation program including benthic lander and glider deployments; IMOS profiling mooring and local industry data have also assisted the project by facilitating model calibration and water mass characterisation. Project 3: Bathymetric and seafloor survey of the Huon Australian Marine Park, Southern Tasmania Investigator will undertake benthic habitat mapping within the Huon Marine Park during IN2020_V10 on behalf of Parks Australia. Operations will be Multi-beam echo sounder (MBES) backscatter mapping including benchmark remapping, azimuth repeatability and supplementary data acquisition. This process will also include concurrent bathymetry data.

The remaining time can be available for multiple Piggyback Projects. Some opportunistic mapping has been prepared should we be ahead of schedule.

RV Investigator Voyage IN2021_V02 (mnf:IN2021_V02_VOYAGE)

The Southern Ocean has a predominant role in the movement of heat and carbon dioxide into the ocean interior moderating Earth’s average surface climate. The IMOS SOTS sub-facility uses a set of two automated moorings to measure these processes under extreme conditions, where they are most intense and have been least studied. The atmosphere-ocean exchanges occur on many timescales, from daily insolation cycles to ocean basin decadal oscillations and thus high frequency observations sustained over many years are required. The current context of anthropogenic forcing of rapid climate change adds urgency to the work. The primary objective is to first deploy a new set of SOTS moorings (SOFS-9 and SAZ-22) and then recover the existing SOTS moorings (SOFS-8 and SAZ-21). Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges: • the SAZ sediment trap mooring collects samples to quantify the transfer of carbon and other nutrients to the ocean interior by sinking particles and investigate their ecological controls. • the Southern Ocean Flux Station (SOFS) mooring measures meteorological and ocean properties important to air-sea exchanges, ocean stratification, waves, currents and biological productivity and ecosystem structure. Water samples are collected for more detailed nutrient and plankton investigations after recovery. Ancillary work will obtain supporting information on atmospheric and oceanographic conditions using CTD casts, underway measurements, Triaxus towed body, Continuous Plankton Recorder and autonomous profiling Biogeochemical-Argo floats, and potentially casts of a bio-optical sensor package.

Australian National Network in Marine Science Student Training Voyage.The voyage took place off the Tasmanian and Australian coast in two legs from Hobart to Broome via Freemantle. The primary objective is to train Australian undergraduate and postgraduate students in ship-based marine science. This objective will be pursued by guiding them to undertake a survey of the Leeuwin Current, starting from its extension into the Southern Ocean and continuing upstream towards its tropical origins off northwest Australia.

RVSS - 2010 Transit Voyage 02 (mnf:SS2010_T02_VOYAGE)

Southern Surveyor Transit Voyage SS2010_T02, Fremantle to Hobart. Scientific Objectives The Benthic Protection Zone (BPZ) of the Great Australian Bight Marine Park (GABMP) was proclaimed in 1998, and consists of a 20 nautical-mile-wide strip of seafloor orientated north to south and extending from three nautical miles from the coast to the edge of Australia’s Exclusive Economic Zone (EEZ), 200 nautical miles offshore (Figure 1). Within this zone, the benthic assemblages are protected from demersal trawling and other potentially destructive human activities. The BPZ is presently one of fourteen temperate Commonwealth Marine Protected Areas (MPAs) in Australia. These MPAs form part of an integrated strategy for marine conservation and management through the National Representative System of Marine Protected Areas (NRSMPA). At present, no data are available on the benthic biodiversity of the continental slope of the BPZ, or the environmental factors that affect their patterns of distribution and abundance. This research addresses this knowledge gap and aims to provide quantitative information on the regional significance and diversity of the deep-water faunal communities of the BPZ.

RVSS - 2010 Transit Voyage 03 (mnf:SS2010_T03_VOYAGE)

Transit voyage Hobart to Sydney Supported by CSIRO-MAR, MNF, and SIMS Scientific Objectives “Next Wave” is a new programme of the National Facility Research Vessel Southern Surveyor to encourage young scientists to try research at sea, inspired by the success of the 2006 voyage led by Dr Moninya Roughan and supported by ARCNESS. Next Wave provides the additional crew as well as a full scientific staff (electronics, hydro, computing etc) on their transit voyages between ports. SIMS has hosted two recent transit voyages Transit SS03-2008 (Aug08, Gladstone to Sydney) and Transit SS01-2009 (Jan09, Sydney to Wellington), with students from all over Australia. The students and leaders work 12 h shifts between 07:00-23:00 to operate the CTD rosette and N70, XBT casts, a well as underway TSG, fluorometer etc, bird/whale counts, etc.

RVSS - 2010 Transit Voyage 04 (mnf:SS2010_T04_VOYAGE)

The voyage provides an ongoing opportunity to use vessel transit time to complete a national mapping of the upper-mid slope seabed with multi-beam mapping and associated ecological interpretation. The upper-slope and mid-slope seabed 100 m to 1500 m depth range, are regions important for regional marine planning, biodiversity and conservation assessments and fisheries habitat mapping.

RVSS - 2010 Voyage 01 (mnf:SS2010_V01_VOYAGE)

Southern Surveyor research voyage ss2010_v01 PINTS - primary Productivity induced by Nitrogen and Iron in the Tasman Sea. Role of iron and other micronutrients in controlling primary productivity in the Tasman Sea: bioavailability, biogeochemical cycling and sources. Scientific Objectives -Macro- and micronutrients, mainly iron and nitrate, control oceanic primary productivity, phytoplankton community composition and subsequently carbon uptake and generation of radiatively important gases for climate. Assessing key underlying processes that control primary productivity and carbon export to the ocean’s interior such as micro and macro-nutrient bioavailability is required to fully understand the ocean role in controlling climate change and improve modelling approaches. Indeed, data allowing an accurate modelling of iron bioavailability in the oceans is sparse. Although large dust deposition from eastern Australia to the ocean may occur, the Tasman Sea presents a region of great contrast: northern waters are nutrient poor while southern waters are nutrient rich, but low in iron. Consequently, the input of iron via dust to the northern and southern regions may influence nutrient uptake, primary production and nitrogen fixation. The proposed research voyage will study iron bioavailability, sources and its biogeochemical cycling in the surface waters of the Tasman Sea, along with the role of other micronutrients.

RVSS - 2010 Voyage 02 (mnf:SS2010_V02_VOYAGE)

The overall scientific objective is to obtain frequent measurements of surface and deep ocean properties that control the transfer of CO2 from the atmosphere to the upper ocean, and then onwards to the ocean interior in the form of sinking particles. This biological pump drives carbon sequestration from the atmosphere, and writes the sedimentary record. The controls on its intensity are complex and involve processes that vary on daily, weekly, seasonal, and interannual timescales. Obtaining observations with the necessary frequency is not possible from ships. For this reason the NCRIS IMOS Southern Ocean Time Series Facility seeks to obtain this information using automated sensor measurements and sample collections. This voyage will deploy for the first time the Southern Ocean Flux Station (SOFS-1) mooring to obtain in-air and in-sea measurements to better understand the exchange of heat, moisture, and gases between the ocean and atmosphere. It will also recover the Pulse-6 mooring that has been making measurements of temperature, salinity, mixed layer depth, photosynthetically available radiation, oxygen, total dissolved gases, and phytoplankton fluorescence and backscatter. The Pulse-6 mooring also collects 24 paired water samples, approximately weekly, for later measurement of dissolved nitrate, silicate, inorganic carbon, and total alkalinity.

This is a processed dataset at 1 minute interval. Southern Surveyor research voyage ss2010_v03. Physical forcing of productivity on the Kimberley Shelf. Scientific Objectives We propose to investigate the biogeochemical (BGC) cycling in the shallow seas of the Kimberley shelf. Our conceptual model of the region links primary production to the balance between light limitation (due to turbidity), nutrient supply and water column stability. The interaction of these factors can generate aggregations of zooplankton and larval fish communities at the turbidity maxima. A major focus will be quantifying the nutrient inputs from the tidal forcing at the shelf break, from terrestrial runoff or benthic recycling. Based upon the observations and modelling we will assess the impact of climate variability on nutrient pumping across the shelf break. In addition the interaction between the river outflow and tides on two time scales (single tidal cycle [12h] and spring-neap cycle) will be investigated in terms of physics (including underwater light), chemistry and biology. Taken from the ss2010_v03 Voyage Plan.

This is a processed data at 1 minute interval. Southern Surveyor Research Voyage SS2010_v04. Assessing oceanographic delivery of nutrients to Ningaloo Reef Part I : Autumn Dynamics Scientific Objectives Ningaloo Reef is Australias largest fringing coral reef and the basis of a major tourist industry. Though diverse and delicate, coral reefs (and the controls of their productivity) remain poorly understood. Understanding the interaction of the reef with the surrounding ocean is essential for predicting and managing the impacts of human and climate-induced changes, and therefore for the effective conservation of reefs. This proposal is part of a new initiative aimed at providing a scientific basis for determining the oceanographic distance beyond which industrial developments will not damage a reefs ecological processes. This analysis is essential for maintaining guiding sustainable development in the region. We will determine the seasonal differences in the productivity and delivery of nutrients and particles, by the Leeuwin (LC) and Ningaloo Currents (NC) on the continental shelf off Ningaloo Reef, WA, with special emphasis on identifying coastal upwelling mechanisms driving reef production. This work is part of a 3-year funded ARC project (Waite, Roughan, Pattiaratchi, Kotta) comparing reef-based uptake of nutrients from the surrounding ocean with the shelf oceanography delivering materials to the Ningaloo reef. We have applied for a second voyage in summer 2011/12 to complete the study. Taken from the ss2010_v04 Voyage Plan.

RVSS - 2010 Voyage 05 (mnf:SS2010_V05_VOYAGE)

The Biological Oceanography of Western Rock Lobster Larvae. Scientific Objectives Lack of knowledge of Western Australia's fisheries oceanography fundamentally limits understanding of the recruitment of Western Rock Lobster, Panulirus cygnus, in a fishery worth $200-300 million/year to Australia. The life cycle of P. cygnus includes a planktonic "phyllosoma" larval stage that is transported up to 1500 km offshore via ocean currents. Development continues for approximately 9 - 11 months at sea, before juveniles ("puerulus") return over the shelf to recruit to coastal reef areas. Critical to improving the management of this fishery, which is under intensive review, is appropriate process information about the oceanographic mechanisms driving coastal recruitment. The last three years of puerulus settlement have been low, with the latest (2008/09) settlement the lowest in 40 years of monitoring and not explained by the environmental factors previously identified as affecting settlement. The cause of the low settlement represents a key unknown for managers assessing the sustainability of WA's coastal fisheries, and is likely to be driven by variation in food availability during the open-ocean stage of the phyllosoma larvae. Our study will test the hypothesis that the ocean productivity, particularly the nitrate-driven classic food chain supporting diatoms, copepods and other zooplankton, limits phyllosoma growth rate and survival in their oceanic phase. We will execute this study at, or after the peak, of the autumn/winter plankton bloom in the Leeuwin Current, with the aim of quantifying oceanographic parameters crucial to modelling rock lobster larval dynamics.

RVSS - 2010 Voyage 08 (mnf:SS2010_V08_VOYAGE)

Krill in 3-D - Vertical stratification and spatial distribution of krill communities in the East Australian Current. Scientific Objectives Marine predator-prey relationships should remain within certain boundary conditions (Michener and Kaufman, 2007), but few examples consider interspecific interactions in planktonic communities in pelagic marine ecosystems (Hairston et al., 1960; Schlosser, 1982). These ecosystems are often structured with high species diversity at lower and higher trophic levels, but a lower diversity of secondary consumers at mid trophic levels (i.e. a wasp-waist ecosystem, Bakun, 2006), such as pelagic fishes. Euphausiids (krill) likely represent an invertebrate analogue to pelagic fishes in these systems (Bakun, 2006), but this concept is yet to be explored. Competition between larval euphausiids and abundant primary consumers capable of dominating ecosystem resources (i.e. salps) likely control the progression toward a wasp-waist structure, and these competitive interactions are potentially mediated by connection between epipelagic and mesopelagic food webs. The epipelagic and mesopelagic zones of the ocean are defined as 0 to100 m (euphotic zone) and 100 to 1000 m depth respectively. Greater than 90% of the organic matter exported from the epipelagic zone is remineralised into nutrients, microelements and CO2 in the mesopelagic zone, and returned to the surface on decadal scales or less (Karl et al., 2008). The mesopelagic zone therefore significantly dampens the downward transfer of organic matter to the deep ocean, and acts as a positive feedback to global warming. Despite their importance in understanding the efficiency of the biological pump, little is known about the processes that control the remineralisation of CO2 in the mesopelagic zone, or its regional variation. These are considered to be related to the structure of, and relationship between, the epipelagic and mesopel

RVSS - 2010 Voyage 09 (mnf:SS2010_V09_VOYAGE)

Impact of the East Australian Current on water chemistry, bio-optical properties and coastal primary productivity in the NSW region. Scientific Objectives The East Australia Current is the single-most important factor affecting regional productivity along the eastern seaboard of Australia, yet we do not have a good measure of its strength, variability or a complete understanding of its biological impact. This voyage seeks to better understand the interaction of the EAC with the continental shelf in the area north and south of the EAC separation zone off NSW, an important region supporting almost 50% of Australians living near the coast. High-resolution data will be collected to characterise the relationship between physical oceanography, water chemistry (e.g. nutrient distribution and light availability) and primary and secondary productivities. Phytoplankton are responsible for >40% of global photosynthesis and are the energetic ‘base’ of marine foodwebs (Falkowski and Raven 2007). Their productivity is generally determined by the provision of nutrients and light and the degree of herbivorous grazing. It is therefore critical to understand these inter-relationships in order to parameterise this complex and dynamic marine environment for biogeochemical and ecosystem models. This project will use traditional as well as innovative techniques to assess productivity (14-C uptake and bio-optical and fluorescence-based estimates of production) as well as grazing losses. In addition, bio-optical biogeochemical quantities will be measured in-situ and provide much needed data for the wider NSW scientific community to improve remotely-sensed estimates of ocean colour (chlorophyll-a biomass). Shifts in the composition and function of bacterial communities will be assessed using metagenomic approaches and will be related to specific oceanographic features and phytoplankton community characteristics. Finally, nutrient and organic source (fulvic acid) enrichment

Southern Surveyor research voyage charter ss2011_c02.Tsunami Detection Buoy Maintenance for Australian Tsunami Warning System (ATWS). Scientific Objectives: The Australian Tsunami Warning System (ATWS) is a national effort involving the Australian Bureau of Meteorology (Bureau), Geoscience Australia (GA) and Emergency Management Australia (EMA) to provide a comprehensive tsunami warning system capable of delivering timely and effective tsunami warnings to the Australian population by 2009. The project also supports international efforts to establish an Indian Ocean tsunami warning system, and contributes to the facilitation of tsunami warnings for the South West Pacific. Due to the complexity and uncertainty as to whether an undersea earthquake has the potential to generate a tsunami, the observation of sea levels is a critical factor in verifying whether a tsunami has actually been generated. The use of actual sea level observations, as compared with reliance on seismic observations alone, therefore helps to significantly reduce the risk of false tsunami warnings being issued. All Australian-owned buoys, as well as deep-ocean buoys operated by other countries in the Australian region, provide critical data to Australia's tsunami warning system.

RVSS - 2011 Transit Voyage 01 (mnf:SS2011_T01_VOYAGE)

2,000 years of oceanic history offshore Eastern Australia. Scientific objectives -This project will generate high-resolution records of sea-surface temperature [SST] changes that have occurred in the Tasman Sea over the last two millennia. A variety of innovative proxies will be employed and used for comparison with lake records on land. International collaboration is a feature of this program, linking with the Royal Netherlands Institute for Sea Research [NIOZ] to determine past sea-surface temperatures and wind-induced upwelling conditions using specific organic compounds recovered in deep-sea cores, and with the marine radio-isotope laboratory in Bordeaux, France, to accurately date cores over short time scales. De Deckker is to collect samples using a multicorer and a student is to go to NIOZ to analyse the samples under the supervision of Dr Schouten. De Deckker will be assisted by both a research assistant and a PhD student at ANU to extract microfossils and date some of them using the radiocarbon technique. Schmidt is to return to France with some of the samples obtained with the multicorer to date them in her radio-isotope laboratory. Rathburn is to subsample several of the cores with his postgraduate student to study the live infaunal microbiota that live in the upper few cm of the sea floor.

RVSS - 2011 Transit Voyage 02 (mnf:SS2011_T02_VOYAGE)

Towards an understanding of mid-trophic biomass, distribution, variability and energetics in ocean ecosystems. Scientific Objectives: The water column comprises more than 90% of the earths living space and its deep water component is probably the largest and least-known major faunal group on Earth despite its obvious importance at the global scale (Robison, 2009). Biological communities in these habitats are dominated by meso-zooplankton and micronekton (fishes, crustaceans, squids and gelatinous zooplankton, 2-20 cm length) that are crucial to the foodwebs of pelagic and demersal predators (e.g. Bulman et al. 2001. The micronekton of the ocean is involved in a vertical migration from deep to shallow depths and, again, while little understood, probably accounts for the bulk of global ocean biomass. This ecological system is under threat from a broad range of influences including climate change and carbon dioxide (ocean acidification) (Robison, 2009). The Tasman Sea is a high priority region as it is predicted to be a global temperature change hot spot (Cai et al., 2005). This large predicted temperature shift in the Tasman Sea will have major impacts on the structure and function of the ecosystem from biogeochemistry, plankton, micronecton and nekton to depths in excess of 400 m. During this voyage we will be refining methods to interpret basin scale acoustic sampling with targeted mid-water net sampling and multi-frequency acoustic and optical sensing. This refinement will contribute to the IMOS bio-acoustic sampling program.

This is the RVSS underway processed data at 1 minute interval Next Wave. The distribution of pelagic and benthic fauna along Australia's southern seaboard Scientific Objectives: The focus of this program is to give students a taste of what it is like to live and work on an ocean going research vessel and to expose them to some of the different sampling methods and equipment that are used in oceanographic research. The students will have two (quasi) scientific aims, each of which will contribute to our knowledge about Australian waters, as follows: 1) to characterise the macro-fauna inhabiting the benthos at range of depths along Australia's southern coast; 2) to investigate regional surface productivity (POM) and the distribution of pelagic organisms along the southern shelf of Australia. For Kloser, the voyage provides an ongoing opportunity to use vessel transit time to complete a national mapping of the upper-mid slope seabed with multi-beam mapping and associated ecological interpretation. For Reisser, the voyage will facilitate her ongoing research on the distribution, abundance and composition of floating marine debris (FMD) around Australia. Marine debris has become a major hazard to marine life and is also leading to aesthetic degradation, economic losses and human health hazards. At present, limited data exist to quantify and explain the geographical range and content of marine debris in our oceans. Extracted from the voyage plan MNF_ss2011_t03_plan.pdf.

2,000 years of oceanic history offshore southern Australia in combination with National upper slope seabed multi-beam mapping and ecological interpretation Scientific Objectives: Project 1: PI: Prof. Patrick De Deckker This project will generate high-resolution records of sea-surface temperature [SST] changes that have occurred offshore southern Australlia over the last two millennia. A variety of innovative proxies will be employed and used for comparison with lake records on land. International collaboration is a feature of this program, linking with the Royal Netherlands Institute for Sea Research [NIOZ] to determine past sea-surface temperatures and wind-induced upwelling conditions using specific organic compounds recovered in deep-sea cores, and with the marine radio-isotope laboratory in Bordeaux, France, to accurately date cores over short time scales. Project 2: PI: Dr Rudy Kloser Spatial management is becoming increasingly common and Australia leads the world in developing a National Representative System of Marine Protected Areas (NRSMPA) by 2012. However, the NRSMPA by itself will not be adequate to manage and protect the marine environment and spatial management of areas outside the NRSMPA will be required. This places an increased demand on scientists to know the physical structure of those areas and their value to biodiversity and ecosystem function.

Australian-New Zealand GEOTRACES GP13 Australasian GEOTRACES: A collaborative international study of the marine biogeochemical cycles of trace elements and their isotopes along a zonal section (GP13) of the Pacific Ocean east of Australia. Scientific Objectives: This project will undertake an integrated oceanographic transect and dust monitoring program for iron, other trace elements, and their isotopes (TEIs) along the western end of the GP13 zonal section (~30oS) east of Australia. Our innovative measurement and analysis strategy will identify processes and quantify fluxes that control the distributions of key TEIs in the southwestern Pacific Ocean, and establish the sensitivity of these distributions to changing environmental conditions. We will use a series of novel techniques to fingerprint the sources, sinks and internal cycling of TEIs, focussing on the atmospheric delivery of irondust to the remote ocean. This project will provide maximum scientific reward for evaluating future global change, and has strong international collaborative activity under the auspices of the international GEOTRACES (www.geotraces.org) program. Outcomes of this project will be an improved ability to predict climate-driven changes in the supply and biogeochemistry of trace elements in ocean waters around Australia. Our research will quantify the importance of atmospheric dust for marine ecosystem health, help inform Government policy on ocean iron fertilisation as a carbon sequestration strategy, and provide a broad basis for evaluating future climatic changes in coupled atmospheric – ocean processes.

Biological Oceanography of Western Rock Lobster Larvae – Part 2. Scientific Objectives: Lack of knowledge of Western Australia’s fisheries oceanography fundamentally limits understanding of the recruitment of Western Rock Lobster, Panulirus cygnus, in a fishery worth $200-300 million/year to Australia. The life cycle of P. cygnus includes a planktonic “phyllosoma” larval stage that is transported up to 1500 km offshore via ocean currents. Development continues for approximately 9 - 11 months at sea, before juveniles (“puerulus”)return over the shelf to recruit to coastal reef areas. Critical to improving the management of this fishery, which is under intensive review, is appropriate process information about the oceanographic mechanisms driving coastal recruitment. The last three years of puerulus settlement have been low, with the latest (2008/09) settlement the lowest in 40 years of monitoring and not explained by the environmental factors previously identified as affecting settlement. The cause of the low settlement represents a key unknown for managers assessing the sustainability of WA’s coastal fisheries, and is likely to be driven by variation in food availability during the open-ocean stage of the phyllosoma larvae. Our study will test the hypothesis that the ocean productivity, particularly the nitrate-driven classic food chain supporting diatoms, copepods and other zooplankton, limits phyllosoma growth rate and survival in their oceanic phase. We will execute this study at, or after the peak, of the autumn/winter plankton bloom in the Leeuwin Current, with the aim of quantifying oceanographic parameters crucial to modelling rock lobster larval dynamics.

RVSS - 2011 Voyage 05 (mnf:SS2011_V05_VOYAGE)

Southern Surveyor Research Voyage ss2011_v05. The influence of natural hydrocarbon migration and seepage on the geological and biological systems of the offshore northern Perth Basin. Scientific Objectives 1. Map sites of natural hydrocarbon seepage in the offshore northern Perth Basin (Jones,Kennard, Ross, Greinert) On the basis of: ¿ acoustic signatures in the water column, shallow subsurface and on the seabed; ¿ geochemical signatures in rock and sediment samples and the water column, and; ¿ biological signatures on the seabed: document the spatial distribution of seepage sites and characterise the nature of the seepage at these sites (gas vs oil, macroseepage vs microseepage; palaeo vs modern day seepage). 2. Investigate generic structural controls on natural hydrocarbon seepage in the offshore northern Perth Basin, to determine the leaking versus sealing nature of individual faults within linked fault systems (Jones, Kennard). Quantify seepage indicators over sealing structures through surveying the seabed over known oil and gas accumulations, then compare and contrast the results with indicators of seepage over structures with residual hydrocarbon columns that are known to have leaked or be leaking, then use these controls to assess the leaking or sealing nature of other structures in a variety of environments. 3. Assess the influence and potential future impact of natural hydrocarbon seepage on geological and biological systems and anthropogenic activities in Australia¿s southwest margin (Jones, Heap, Greinert). Determine whether the level of natural hydrocarbon seepage within the offshore northern Perth Basin: a) is likely to impact climate change due to methane release in shallow water, b) is a control on benthic habitat distribution, c) presents a natural hazard such as for drilling or slope stability, or d) has the potential to change or influence petroleum prospectivity.

RVSS - 2011 Voyage 06 (mnf:SS2011_V06_VOYAGE)

The Perth Abyssal Plain: Understanding Eastern Gondwana Break-up Scientific Objectives The objectives of this voyage are to investigate; 1. The crustal nature of the Gulden Draak Ridge, Batavia Knoll, and Dirck Hartog ridge -continental and/or volcanic - in order to further constrain plate tectonic models of the early separation between India and Australia and also to understand the interaction between the seafloor-spreading system and volcanism related to theKerguelen hotspot. This objective relates primarily to Nathan Daczko and Jacqueline Halpin. 2. The age and formation history of the 'de Gonneville Triangle'. This piece of oceanic crust is located at what was the triple junction of rifting between Australia-India-Antarctica. Understanding the de Gonneville Triangle is especially important because prior to Australia-Antarctic break-up it was immediately adjacent to the Enderby Basin, and the two basins should reveal the same magnetic anomaly patterns but current interpretations reveal considerable discrepancies. This objective relates primarily to Joanne Whittaker, Dietmar Müller and Simon Williams. 3. The age distribution of oceanic crust across both the east and west Perth Abyssal Plain.Acquiring ridge-perpendicular magnetic anomaly profiles are crucial in order to constrain the early spreading history between India and Australia and the prebreakup fit between India-Antarctica and Australia. Of particular importance is the oceanic crust located southwest of the Dirck Hartog Ridge. Sampling in the Perth Abyssal Plain region will help to resolve uncertainties regarding the early spreading history and the full-fit of the India-Australia-Antarctica triple plate system. This objective relates primarily to Joanne Whittaker, Dietmar Müller and Simon Williams. Taken from Voyage plan, please read plan for full details.

RVSS - 2011 Voyage 07 (mnf:SS2011_V07_VOYAGE)

Integrated Marine Observing System (IMOS) observations for climate and carbon cycle studies southwest of Tasmania (47ºS, 140ºE). The overall scientific objective is to obtain frequent measurements of surface and deep ocean properties that control the transfer of CO2 from the atmosphere to the upper ocean, and then onwards to the ocean interior in the form of sinking particles. This "biological pump" drives carbon sequestration from the atmosphere, and writes the sedimentary record. The controls on its intensity are complex and involve processes that vary on daily, weekly, seasonal, and interannual timescales. Obtaining observations with the necessary frequency is not possible from ships. For this reason the NCRIS IMOS Southern Ocean Time Series Facility seeks to obtain this information using automated sensor measurements and sample collections. This voyage will deploy the Southern Ocean Flux Station (SOFS-2) mooring to obtain in-air and in-sea measurements to better understand the exchange of heat, moisture, and gases between the ocean and atmosphere.

RVSS - 2012 Transit Voyage 01 (mnf:SS2012_T01_VOYAGE)

Southern Surveyor SS2012_T01. XBT fall-rate experiments using XBT/CTD intercomparisons. Scientific Objectives XBT/CTD intercomparison (Rebecca Cowley): We propose a simple and reliable experiment to assess the fall-rate and temperature biases of modern XBTs manufactured by Lockheed Martin Sippican (the major global supplier). We aim to collect concurrent temperature profiles form both XBT systems and high accuracy CTD systems. We have some old XBT probes which we would like to deploy to compare with modern probes. We plan to address the questions: 1. Do modern XBTs have temperature and depth biases? 2. Do older XBTs (circa 2001-2003) show similar temperature and depth biases to those found in previous work? 3. Can we use depth soundings to check depth accuracy, and how do these results compare with the CTD/XBT intercomparison method? Piggy-back Projects Rudy Kloser (CMAR) Rudy’s project is SWATH mapping of the 200m to 1000m depth range, particularly along the northern edge of Bass Canyon.

RVSS - 2012 Transit Voyage 02 (mnf:SS2012_T02_VOYAGE)

This is a underway dataset with 1 minute time interval Southern Surveyor Transit Voyage ss2012_T02. Great Barrier Reef phase shift: Gardner Banks to Gardner Reef On a global scale, coral reefs are experiencing a period of rapid change. The world has effectively lost 19% of the original area of coral reefs since 1950, with the loss predicted of 35% of coral reefs in the next 40 years (Wilkinson, 2008). About 46% of coral reefs are regarded as healthy except for currently unpredictable global climate threats, which includes the Great Barrier Reef (GBR). The vulnerability of coral reef habitats to climate change is high as scleractinian corals are highly sensitive to increasing sea temperature and ocean acidification (Marshall and Johnson, 2007). The increased frequency of coral bleaching due to further increases in sea surface temperature (SST) will cause a decline in coral cover, increases in algal dominance, and shifts towards species that are more thermally tolerant. Exceptions to this pattern may occur at the southern limits of the GBR where tropical carbonates transition into temperate carbonates. The observed shift of average marine climate zones south by >200 km since 1950 (Lough, 2008) could potentially result in the GBR extending south, causing an algal to coral phase shift as coral settlement follows the changing environmental gradient.

RVSS - 2012 Transit Voyage 03 (mnf:SS2012_T03_VOYAGE)

MNF Southern Surveyor RV ss2012_t03. Predicting the sources, distribution and fate of floating marine debris. Scientific Objectives: Marine debris has become a major hazard to marine life through ingestion and entanglement and is also leading to aesthetic degradation, economic losses and human health hazards. The increase in amounts of marine debris can be attributed to at least three factors: (1) plastics replaced natural fibers in the manufacture of many everyday items; (2) plastics are often less expensive than the materials they replace,thereby decreasing incentives to reuse or recycle items; (3) there are simply more ships and coastal residents that can lose or discard materials. Monitoring studies are needed to assess the effectiveness of governments’ actions in reducing the overall amount of marine debris as well as certain types of debris of particular concern, such as fishing gear and microplastics. For the first time, floating marine debris (FMD) will be systematically sampled in oceanic waters close to east coast of Australia. This voyage will provide us the opportunity to collect samples over a broad range of latitudes. These data will be useful to test a hypothesis recently proposed by marine researchers: FMD concentrations tend to be higher at subtropical latitudes. The general aim of this project is to estimate FMD composition and concentration (pieces/km2) at different locations around Australia.

This is underway dataset with 1 minute time interval MNF Southern Surveyor research voyage SS2012_t07. 1) Epibenthic communities of northern Australia (Belinda Alvarez de Glasby(MAGNT)). 2) An examination of the microbial oceanography of north-eastern Australia (Martina Doblin (UTS). Scientific Objectives (1) 1. To use a remotely operated underwater video camera (ROV) to explore two areas along the transit voyage track of RV Southern Surveyor from Darwin to Cairns for discovery of habitat-forming and bioactive epibenthic fauna. 2. To collect epibenthic fauna using a sled thereby ground-truthing the video data. 3. To sort, photograph, document and prepare taxonomic vouchers of the samples captured with the benthic sled. 4. To deposit taxonomic vouchers of all samples at MAGNT for curation, registration and distribution to the appropriate taxonomic experts for taxonomic identification. 5. To prepare and freeze suitable samples for screening of bioactive compounds and accession them at the AIMS Bioresources library for future export to the US National Cancer Institute (NCI) laboratories or for research on marine natural products. 6. To correlate biodiversity measure obtained from the survey with available physical datasets from GA (e.g. geomorphology, sediment grain-size). Scientific Objectives (2) The major biotic players in controlling the function of the global ocean are microorganisms. To fully understand the basic biological and chemical dynamics of ocean ecosystems, the identity and role of the microbial assemblages inhabiting seawater must be accurately defined. The proposed research will provide an important new platform for understanding the ecology and biogeochemistry of this region. The specific objectives of the proposed research are to: 1. Provide a first characterisation of the taxonomy, diversity and biogeography of prokaryotic and eukaryotic microorganisms inhabiting Australia's NE ocean waters; 2. Assess the physiological and biogeochemical potential of the microbial communities inhabiting this region; 3. Characterise the light climate to define optical niches for growth of marine primary producers and undertake manipulative experiments to examine optical regulation of carbon fixation; 4. Characterise the eco-physiology and fine-scale community structure of abundant microbial primary producers, including Prochlorococcus, Synechococcus and photosynthetic pico-eukaryotes; 5. Establish and test new microbial oceanography experimentation protocols, while also providing valuable training to students and early career researchers in oceanographic research practices.

RVSS - 2012 Voyage 01 (mnf:SS2012_V01_VOYAGE)

This is a QC underway dataset with 1 minute time interval Southern Surveyor Voyage ss2012-V01. Sustained Monitoring of the East Australian Current:Mass, Heat and Freshwater Transports. Scientific Objectives The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia. It provides both the western boundary of the South Pacific gyre and the linking element between the Pacific and Indian Ocean gyres. This voyage will deploy an array of full-depth current meter and property (CTD) moorings from the continental slope to the abyssal waters off Brisbane (26oS). At this location the EAC, north of the high eddy variability, the approaching its maximum strength and its flow is relatively uniform and coherent. The aim of this observing system is to capture the mean and time-varying flow of the EAC.

RVSS - 2012 Voyage 02 (mnf:SS2012_V02_VOYAGE)

This is a raw underway dataset with 1 minute time interval The northern Lau Basin is a region of rapidly extending and newly-forming crust, seamed by multiple zones of sea-floor spreading, rifting, and faulting consequent to the clockwise rotation of the Tonga Arc away from the Fiji-Lau Ridge (Fig. 1a). Demise of the former Vitiaz Arc has led to the establishment of a new Australian-Pacific plate boundary that wraps around the north end of Fiji, and connects with the Tonga Trench via a set of ridges (e.g., Futuna Spreading Centre, Northwest Lau Spreading Centre), rifts (e.g., Rochambeau Rifts), transform faults, and extension zones (Fig. 1b). Voyage ss2012-v02 will explore via a west to east reconnaissance of these tectonic elements, the accompanying magmatism and hydrothermal activity. The principal investigators and their shipboard scientific colleagues will collaborate in studies of the petrology and geochemistry of the volcanic rocks (including major and trace element abundances, isotopic characteristics), and water column geochemical compositions.

RVSS - 2012 Voyage 04 (mnf:SS2012_V04_VOYAGE)

This is the underway dataset with 1 minute time interval MNF Southern Surveyor research voyage SS2012_v04. Observations of remarkable eastward flows and eddies in the subtropical southeast Indian Ocean. Scientific Objectives: Our work will include a suite of CTD, microstructure, surface drifter and float observations, and a mooring that will contribute to answering a first-order gap in our understanding of the large-scale currents in the subtropical southeast Indian Ocean. The presence of a near-surface, eastward flow across the South Indian Ocean is a remarkable aspect of the upper-ocean circulation because it flows against the westward direction from Ekman and Sverdrup theory for this region. However the underlying mechanisms, driving the eastward surface currents and their eventual interaction with the Leeuwin Current and down welling remains unclear. Our primary goal in this work is to make new observations of the physical and biogeochemical structure of the eastward flows in the region between existing observations and the Australian coast, where their fate is unknown. This region is filled with energetic eddies generated by the Leeuwin Current. Our observations will also provide insight into the nature of the interaction of these eddies with the circulation and productivity of the interior Indian Ocean. Dynamical understanding of the Indian Ocean circulation is central to the outstanding problem in ocean climate projections of correctly including surface processes to project the spatial patterns of heat uptake, steric sea-level rise, and storage of carbon dioxide. Piggy-back Projects include : Upper-ocean mixing estimates using a VMP-200 microstructure profiler, Nitrogen uptake in the eastward flows feeding the Leeuwin Current System, Phytoplankton dynamics in the eastward flows feeding the Leeuwin Current System and Offshore sources of high nitrate, low oxygen upper ocean waters.

RVSS - 2012 Voyage 05 (mnf:SS2012_V05_VOYAGE)

This is a QCed underway dataset with 1 minute time interval MNF Southern Surveyor research voyage SS2012_v05. IMOS: Sustained observations of the Timor Passage and Ombai Strait components of the Indonesian Throughflow. Scientific Objectives: The Indonesian seas are the only major low-latitude connection in the global oceans (Figure 1). This connection permits the transfer of Pacific waters into the Indian Ocean, known as the Indonesian Throughflow. The Indonesian Throughflow actually consists of several filaments of flow that occupy different depth levels and weave their way through the complex island geometry comprised of broad shallow shelves and deep basins. The largest Indonesian seas are: the shallow Java Sea, the deeper Flores, Banda and Timor Seas, and the shallow Arafura Sea. The Indonesian Throughflow has a major influence on both the climate of the Indian Ocean and the global oceans. It is an important pathway for the transfer of climate signals and their anomalies around the world’s oceans. While the heat and fresh water carried by the Indonesian Throughflow are known to affect the basin budgets of both the Pacific and Indian Oceans, the Indonesian Throughflow is poorly simulated in ocean circulation, seasonal prediction and climate models.

RVSS - 2012 Voyage 06 (mnf:SS2012_V06_VOYAGE)

This is a processed underway dataset with 1 minute time interval MNF Southern Surveyor research voyage SS2012_v06. Tectonic framework for the easternmost Coral Sea and northern extent of the Lord Howe hotspot. Scientific Objectives The main objectives of this voyage are to investigate: 1. The nature of the crust (continental/volcanic/oceanic) underlying Rennell Island, East Rennell Island Ridge, South Rennell Fracture Zone and d’Entrecasteaux Zone by directly sampling and comparing the basement from each of these submarine plateaus and ridges. This objective relates primarily to Sebastein Meffre, Steven Micklethwaite, Julien Collot and Maria Seton. 2. The age and structure of the Santa Cruz/Torres and d’Entrecasteaux Basins through magnetic profiling and explore whether they share a spatial and temporal relationship. We will also explore whether the basins formed in a back-arc setting related to Cretaceous or Eocene subduction or whether they preserve a piece of oceanic crust from the Panthalassa Ocean. This objective relates primarily to Maria Seton, Dietmar Muller, Christian Heine and Julien Collot. 3. The extension of the Lord Howe hotspot trail into the eastern Coral Sea, north of the Bellona Plateau by directly sampling extinct volcanic edifices and exploring whether the West Torres Plateau is capped by volcanics. This objective relates primarily to Sebastein Meffre and Maria Seton.

RVSS - 2012 Voyage 07 (mnf:SS2012_V07_VOYAGE)

This is underway dataset with 1 minute time interval Southern Surveyor SS2012_V07. Tasmantid Seamounts: volcanic, tectonic, and carbonate record. Scientific Objectives : The Tasmantid seamounts are a chain of underwater hotspot-derived intraplate volcanoes situated 150 to 600 km east of the Australian mainland (Figure 1). Because of the long record of hotspot-derived volcanic activity - spanning more than 2000 km and >40 million years - the seamounts provide an exceptional and largely untapped record of Australian plate velocity. Deciphering this record by obtaining volcanic samples suitable for high-resolution 40Ar/39Ar geochronology is a major objective of this expedition (Cohen, Vasconcelos, Knesel). Such volcanic samples will also record the chemical evolution of a long-lived mantle plume, and chemical analyses will reveal information on mantle reservoirs, melting, magma diversification, and the contrasting contamination effects of thinned continental lithosphere in the north versus oceanic lithosphere in the south (Knesel, Arculus). Geophysical data will also be collected over the seamounts and oceanic crust of the Tasman Sea to help study the tectonic history and lithospheric structure of the region. The larger seamounts are variably capped by fossil and modern coral reefs and/or other carbonate sediments (Webb). Although not targeted specifically, where carbonate materials are recovered with the volcanic rocks this material will provide a key biologic and climatic record of the seas east of Australia. Morphologic analysis of the seamounts will allow identification of volcanic and coral-growth geomorphology, as well as any mass wasting deposits (Cohen, Webb).

RVSS - 2013 Charter Voyage 02 (mnf:SS2013_C02_VOYAGE)

AMNF RV Southern Surveyor - Research Charter ss2013_C02. RV Southern Surveyor Research Charter - Great Australian Bight. Scientific Objectives: Study of benthic ecosystems and natural hydrocarbon seepage in deep (200-3,000 m) waters of the Great Australian Bight (GAB) are part of the focus of a research program (the GAB Science Plan). The Science Plan aims to describe key elements of marine ecosystems across the GAB, including in the deep central GAB area associated with oil and gas exploration activity. Characterising benthic ecosystem structure and function is important because there are virtually no existing benthic biological data beyond continental shelf depths (< 200 m) in the GAB. Conservation values attributed to Commonwealth Marine Reserves (CMR) spanning wide depth ranges are untested on the mid- and lower continental slope, while oil and gas lease areas extend across the GAB Marine Park (GAB MP). The benthic ecosystem description will be strengthened with context provided by an improved understanding of hydrocarbon seeps and migration pathways in the GAB. The objectives of several projects within the Science Plan will be partly met by results from this voyage.

AMNF RV Southern Surveyor - Research Transit Voyage. Oceanographic Methods training unit- (part of the Master of Marine and Antarctic Science degree program- IMAS, University of Tasmania) Scientific Objectives This voyage will provide students with experience at sea and training in standard methods in chemical and biological oceanography The main objectives are to have students (after completing this voyage) able to: - plan a scientific voyage at sea - describe how different scientific instruments work, their area of use, limitations, and nature of collected data - analyze, interpret and present data from a subset of oceanic instrumentation - write a scientific report - understand the working routines onboard a research vessel such as the Southern Surveyor

RVSS - 2013 Transit Voyage 02 (mnf:SS2013_T02_VOYAGE)

AMNF Southern Surveyor research voyage SS2013_t02. The benthic fauna of the Great Australian Bight Scientific Objectives: The focus of this program is to give students a taste of what it is like to live and work on an ocean going research vessel and to expose them to some of the different sampling methods and equipment that are used in oceanographic research. The students will have three quasi scientific aims as follows: 1) to sample and characterise the benthic communities in the Great Australian Bight (GAB); 2) to investigate surface and water column productivity along Australia’s southern seaboard; 3) to map Australia’s seafloor. The students will be involved in all aspects of the research – sorting and curating the fauna – milking the rosette/changing the filters and measuring the dissolved oxygen and salinity – operating and monitoring the swath. Outside of sampling stations and designated tasks, students will take it in turns to watch for marine mammals and we may supplement the sampling and research with a series of lectures and practicals utilising the material/data collected. For Keith, the voyage provides an ongoing opportunity to use vessel transit time to complete a national mapping of the upper-mid slope seabed with multi-beam mapping and associated ecological interpretation. The upper-slope and mid-slope seabed 100 m to 1500 m depth range, are regions important for regional marine planning, biodiversity and conservation assessments and fisheries habitat mapping. The swath mapping will be integrated as a part of the student activities and there is a 12h portion of the transit dedicated to targeting some canyons off Esperance and filling the swath track adjacent to the 500 m isobath. For Tanner & Williams the voyage provides an opportunity to gain further specimens and add a temporal aspect to their study of the epifaunal assemblages (benthic) of the GAB Marine Park and its surrounds. The GAB is a unique ecosystem, with diversity similar to the Great Barrier Reef, and a much higher proportion of endemic species, but only a fraction of the scientific effort.

(2) To understand the detailed geomorphology of the submerged reefs and shelf edge features at these northern and southern limits. (3) To collect swath data in those parts of the upper-slope that currently have no swath data. 4. Greenhouse gas measurement, lead by Dagmar Kubistin at UoW The project aims to improve our understanding of the sources, sinks and background concentrations of key greenhouse gases in the Southern Hemisphere. (1) Make continuous measurements of carbon dioxide, methane, nitrous oxide, carbon monoxide and ozone as the RV Southern Surveyor travels along the chosen transect; (2) Assimilate measured data into a variety of atmospheric chemical transport, inverse and statistical models to improve our knowledge and understanding of atmospheric greenhouse gases and their sources and sinks.

RVSS - 2013 Transit Voyage 04 (mnf:SS2013_T04_VOYAGE)

This is a raw underway dataset with 1 minute time interval MNF Southern Surveyor research voyage SS2013_t04. Use the EM300 to search and survey HMAS Australia and HMAS Voyager. Scientific Objective: This work forms part of a wider study to investigate the site formation processes of deepwater shipwrecks. The debris field of the HMAS Australia wreck has never been adequately explored. This work will explore the extent of the debris field from the wreck, including the location of loose guns (rifled cannons) and funnels which were stored on deck, along with the location of the gun turrets which would have fallen out of their mounts during the sinking. These surveys will be the deepest survey of a wreck in NSW water and will provide baseline data for future potential research projects at the University of Sydney and internationally. When used in conjunction with other deepwater Australian shipwreck inspections (eg HMAS Sydney/ Kormoran and Centaur), the proposed survey will contribute further to the understanding of the site formation processes (ie how shipwreck sites form and deteriorate) and the physical decomposition processes of deep water wrecks. Scientific Objectives: The project aims to improve our understanding of the sources, sinks and background concentrations of key greenhouse gases in the Southern Hemisphere. a) Make continuous measurements of carbon dioxide, methane, nitrous oxide, carbon monoxide and ozone as the RV Southern Surveyor travels along the chosen transect; b) Assimilate measured data into a variety of atmospheric chemical transport, inverse and statistical models to improve our knowledge and understanding of atmospheric greenhouse gases and their sources and sinks.

RVSS - 2013 Voyage 01 (mnf:SS2013_V01_VOYAGE)

Southern Surveyor SS2013_V01. Submarine landslides offshore northern New South Wales and southern Queensland: their geomechanical characteristics, timing and triggers. Scientific Objectives: An extensive region of the continental slope located offshore Northern NSW and Southern Queensland between Byron Bay and the southern tip of Fraser was demonstrated to have experienced intense submarine erosion dominated by submarine landsliding in 2008 (SS 12/2008, Boyd, Keene, Gardner, Exon, Hubble et al). Major questions about the geographic extent of the area affected by these processes, the geomechanics and dynamics of sliding; the timing and frequency of sliding; and the potential trigger mechanism for slide initiation have arisen from the analysis of the material collected by the scientists who participated in the SS12/2008 voyage. These workers and their colleagues (Hubble, Airey, Clarke, Yu, Keene, Boyd et al) demonstrated that submarine landsliding on Eastern Australia’s continental margin is unexpectedly young and frequent at geological timescales. They have also developed geological and geotechnical models which attempt to explain the apparent youth and unexpected frequency of submarine landsliding in this area of the eastern Australian continental margin. This project will extend the findings of the SS 12/2008 work by collecting data that will help to validate or modify the models developed to explain the areas submarine erosion and landsliding. This will be achieved by collecting additional core and dredge samples in the original study area and by extending the coverage of detailed bathymetric to the north of the 2008 study area; and by sampling appropriate features in the area identified in the area where this new bathymetric mapping of the outer shelf and slope will be undertaken.

This is a raw underway dataset with 1 minute time interval AMNF Southern Surveyor research voyage SS2013_v04. Observations of remarkable eastward flows and eddies in the subtropical southeast Indian Ocean. Scientific Objectives: Our work will include a suite of CTD, microstructure, surface drifter and float observations,and a mooring that will contribute to answering a first-order gap in our understanding of the large-scale currents in the subtropical southeast Indian Ocean. The presence of a near-surface, eastward flow across the South Indian Ocean is a remarkable aspect of the upper-ocean circulation because it flows against the westward direction from Ekman and Sverdrup theory for this region. The flow often appears as a set of distinct currents and jets. These currents have been detected in observations and simulated in some numerical models. However the underlying mechanisms driving the eastward surface currents and their eventual interaction with the Leeuwin Current and downwelling against the coast remains unclear. Furthermore, they appear to be linked to the Indonesian Throughflow and Southern Ocean water masses formed south of Australia. Our primary goal in this work is to make new observations of the physical and biogeochemical structure of the eastward flows in the region between existing observations and the Australian coast, where their fate is unknown. This region is filled with energetic eddies generated by the Leeuwin Current. Our observations will also provide insight into the nature of the interaction of these eddies with the circulation and productivity of the interior Indian Ocean. Dynamical understanding of the Indian Ocean circulation is central to the outstanding problem in ocean climate projections of correctly including surface processes to project the spatial patterns of heat uptake, steric sea-level rise, and storage of carbon dioxide.

RVSS - 2013 Voyage 05 (mnf:SS2013_V05_VOYAGE)

This is a raw underway dataset with 1 minute time interval AMNF Southern Surveyor research voyage SS2013_v05. Scientific Objectives: The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia. It provides both the western boundary of the South Pacific gyre and the linking element between the Pacific and Indian Ocean gyres. This voyage will retrieve an array of full-depth current meter and property (CTD) moorings from the continental slope to the abyssal waters off Brisbane (26oS). At this location the EAC, north of the high eddy variability, the approaching its maximum strength and its flow is relatively uniform and coherent. The aim of this observing system is to capture the mean and time-varying flow of the EAC. This a component of IMOS, and will provide an intensive reference set of measurements of the EAC flow over sustained period for monitoring EAC transport, improved understanding of relationship of EAC and the South Pacific gyre and impact of the coastal marine ecosystem, and validation and interpretation of the current system in numerous climate and ocean models. The mooring array is located on the existing long-term XBT transects, satellite altimetry and glider tracks. The EAC deep mooring array has been complemented by a Queensland- IMOS operated inshore mooring array on the continental shelf region.

RVSS - 2013 Voyage 06 (mnf:SS2013_V06_VOYAGE)

This is a raw underway dataset with 1 minute time interval Scientific Objectives: The overall scientific objective is to obtain frequent measurements of surface and deep ocean properties that control the transfer of CO2 from the atmosphere to the upper ocean, and then onwards to the ocean interior in the form of sinking particles. This “biological pump” drives carbon sequestration from the atmosphere, and writes the sedimentary record. The controls on its intensity are complex and involve processes that vary on daily, weekly, seasonal, and inter-annual timescales. Obtaining observations with the necessary frequency is not possible from ships. For this reason the IMOS Southern Ocean Time Series Facility seeks to obtain this information using automated sensor measurements and sample collections. Recovery and Deployments: Recovery of: SOFS-4 mooring, Pulse-10 mooring, SAZ-15 mooring. Ancillary work includes underway and CTD sensor measurements and sample collections, and potentially zooplankton net sampling and towing of a continuous plankton recorder (CPR).
