Harbour porpoise sightings type unknown (9)

This dataset illustrates the Harbour porpoise sightings for which the sighting type (effort, incidental etc.) around the Baltic Sea are unknown. Data includes only few sightings. The data originates from the ASCOBANS Harbour porpoise database hosted previously by German Forschungs- und Technologiezentrum Westküste der Christian-Albrechts-Universität zu Kiel (FTZ). Updates (new sightings and features) to this HELCOM-ASCOBANS database were received from HELCOM Contracting Parties last time during spring 2010. The country EEZ, basin and subbasin where the sighting has been made are given. Also Country responsible for the reporting and some additional information have been given. One row in the data may present more than one individual.

Harbour porpoise incidental sightings (11)

This dataset illustrates the numbers of incidental Harbour porpoise sightings around the Baltic Sea, including both historical and recent numbers.

Baltic aphotic muddy sediment characterized by sea-pensThe HELCOM Red List of Baltic Sea underwater biotopes, habitats and biotope complexes (2013) is an updated and improved version of the Red List assessment of marine and coastal biotopes and biotope complexes published in 1998. The classification of the report follows the proposed International Union for Conservation of Nature (IUCN) criteria and assessment principals but with some modifications for the Baltic Sea.Altogether, the HELCOM Underwater Biotope and habitat classification (HELCOM HUB) includes 209 biotopes of which 59 were red-listed. Many of the red-listed biotopes are located in deep areas of the Baltic Sea due to oxygen-free nature as well as in the southwestern Baltic Sea due to the salinity restricted distribution of species in certain biotope. The HELCOM assessment relies heavily on expert judgment and inference, and the questionnaire data represents the estimated presence-absence data not in-situ measured data. This must be taken in account when observing the map presentation. The biotopes are shown on the map using the EEA 100 km grid. This dataset displays estimated presence of AB.H2T1 according to HELCOM RED LIST assessment experts:Because of its salinity and depth requirements, this habitat occurs mostly in the deeper parts of Kattegat. The most common sea pen species Virgularia mirabilis and Pennatula phosphorea have been observed for example in the deep trenches of the Kattegat (The Kattegat trench, the Ddupa Rännan trench), in the Groves Flak and near the island Ven in the Sound. The habitat has likely suffered from bottom trawling as trawling marks and badly disturbed seabeds has been recorded in the area of their distribution. Distribution map indicates the area in the 100 x 100 km grid where biotopes are known to occur.(Data (expert judgements) collected in HELCOM RED LIST project, released in May 2013)

This dataset displays estimated presence of AB.B1E4 according to HELCOM RED LIST assessment experts:Known from German and Polish waters in the Baltic Sea. Aphotic hard clay dominated by Astarte spp. occurs on the sills (thresholds) of the Słupsk Furrow that connects the Bornholm Deep with the Gotland Deep and Gdańsk Deep.
