Description: Sedimentation rates are part of EMODnet 3 (European Marine Observation and Data network) Geology, Work Package 3 (WP3) Seabed substrate. The objective of WP3 is to compile all available seabed substrate information on a scale of 1:100 000 or finer from all European seabed areas, and to update sedimentation rate data collected in the previous phases. WP3 has compiled and harmonized all available information on the rate of sedimentation on the seafloor. The information on sedimentation rates for recent sediments is presented as point-source information. Estimations of modern sedimentation rates (centimetres/year) can be based e.g. on established historical records of anthropogenic radionuclides (e.g. 137Cs and 241Am), polychlorinated biphenyls (PCBs), lead (Pb) and stable lead isotope (206/207Pb ratios). Sedimentation rate estimations can be based also on varve/laminae counting, radionuclide 210Pb and 14C decay dating methods. In addition stratigraphic marker horizons, like in the Baltic Sea, horizons formed by documented Major Baltic Inflow (MBIs) events (Moros et al. 2017), can be used in the estimations. Project partners have delivered information on accumulation/sedimentation rates available in their national waters including their EEZ. Here we focus on modern/present day sedimentation rates. That mean sedimentation rates over the past decades, since AD 1900 or so. Further information about the EMODnet-Geology project is available on the portal (http://www.emodnet-geology.eu/).
Description: Seabed substrate map of the European marine areas (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. The 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. 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 seabed substrate map was produced in March 2018. The latest update was in January 2019. Note: The data may include some errors e.g. data discontinuities.

Description: Seabed substrate maps of the European marine areas (e.g. the Baltic Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, and the Mediterranean Sea within EU waters) at 1:1 000 000, 1: 250 000, 1:100 000 and 1:50 000 scales. The maps at all scales are collated and harmonized from seabed substrate information within the three subsequent EMODnet Geology projects running since 2009 with an objective to assemble marine geological information from all European sea areas. The latest EMODnet Geology III project started in 2017 with 39 marine departments of the geological surveys of Europe (from 30 countries).

The seabed substrate multiscale product was compiled in January 2019. Note: The data may include some errors e.g. data discontinuities.

Description: 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.
