Seabed substrate maps of the European Seas at 1:1 000 000, 1:250 000 and 1:100 000 scales, and map showing sedimentation rates at the seafloor. Seabed substrate maps at 1: 1 000 000, 1: 250 000 and 100 000 scales are collated and harmonized from seabed substrate information. The latest EMODnet-Geology III project started in 2017 with 39 marine departments of the geological surveys of Europe from 30 countries. The sedimentation rate map of the European Seas shows point-source data based on e.g. 137Cs or 210Pb dating.
Available map layers (4)
Seabed_substrate_1M (Seabed_substrate_1M)
Seabed substrate map of the European sea areas (e.g. the Baltic Sea, the Barents Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, the White Sea, and the Mediterranean Sea within EU waters) at 1: 1 000 000 scale (1M). The map is collated and harmonized from seabed substrate information within the EMODnet-Geology project. Map is collated from the 1M data from Partners and generalized 1:250k EMODnet data. Where necessary, the existing substrate classifications (of individual maps) have been translated to a scheme that is supported by EUNIS. This EMODnet reclassification scheme consists of altogether five seabed substrate classes. Four substrate classes are defined on the basis of the modified Folk triangle (mud to sandy mud; sand; coarse sediment; and mixed sediment) and one additional substrate class (rock and boulders) was included by the project team. If the original seabed substrate dataset has enabled more detailed substrate classification, classifications with 7 and 16 substrate classes might be available. The seabed substrate map was produced in October 2016. Note: The data may include some errors e.g. overlays, topological gaps and data discontinuities.
Seabed_substrate_250k (Seabed_substrate_250k)
Seabed substrate map of the European marine areas including (e.g. the Baltic Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, and the Mediterranean Sea within EU waters) at 1: 250 000 scale (250k). The map is collated and harmonized from seabed substrate information within the EMODnet-Geology project. Where necessary, the existing seabed substrate classifications (of individual maps) have been translated to a scheme that is supported by EUNIS. This EMODnet reclassification scheme includes at least five seabed substrate classes. Four substrate classes are defined on the basis of the modified Folk triangle (mud to sandy mud; sand; coarse sediment; and mixed sediment) and one additional substrate class (rock and boulders) was included by the project team. If the original seabed substrate dataset has enabled more detailed substrate classification, classifications with 7 and 16 substrate classes might be available. The EMODnet-Geology project started in 2013 with 36 marine departments of the geological surveys of Europe (from 30 countries), with an objective to assemble marine geological information from all European sea areas. The seabed substrate map was produced in October 2016. Note: The data may include some errors e.g. data discontinuities.
Seabed_substrate_100k (Seabed_substrate_100k)
Seabed substrate map of the European marine areas including (e.g. the Baltic Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, and the Mediterranean Sea within EU waters) at 1:100 000 scale (100k). The map is collated and harmonized from seabed substrate information within the EMODnet-Geology III project. Where necessary, the existing seabed substrate classifications (of individual maps) have been translated to a scheme that is supported by EUNIS. This EMODnet reclassification scheme includes at least five seabed substrate classes. Four substrate classes are defined on the basis of the modified Folk triangle (mud to sandy mud; sand; coarse sediment; and mixed sediment) and one additional substrate class (rock and boulders) was included by the project team. If the original seabed substrate dataset has enabled more detailed substrate classification, classifications with 7 and 16 substrate classes might be available. The EMODnet-Geology III project started in 2017 with 39 marine departments of the geological surveys of Europe (from 30 countries), with an objective to assemble marine geological information from all European sea areas. The seabed substrate map was produced in March 2018. Note: The data may include some errors e.g. data discontinuities.
Sediment_accumulation_rates (Sediment_accumulation_rates)
Sedimentation rate map of the European Seas (e.g. the Baltic Sea, the North Sea, the Barents Sea, the sea around Iceland, the Iberian Coast, the Western Mediterranean Sea (within EU waters), the Adriatic Sea, the Ionian Sea and the Central Mediterranean Sea (within EU waters), the Aegean-Levantine Sea (within EU waters including the Turkish sector) and the Black Sea. The map is collated and compiled within the EMODnet-Geology project. Estimations of modern sedimentation rates (cm/year) are based mainly on the 137Cs and the 210Pb dating. The 137Cs could be used as a timemarker in the sediment column. In the sediment column the activity peak of 137Cs corresponds to the fallout of the Chernobyl nuclear power plant accident of April 1986. Some sedimentation rates were estimated from acoustic-seismic and sediment core data. This version was produced in 10.10.2016
