EUSeaMap (2023) Broad-Scale Predictive Habitat Map - Substrate type (a habitat descriptor)

Classified seabed substrate types for European seas. Produced by EMODnet Seabed Habitats as an input layer for the 2023 EUSeaMap broad-scale habitat model, based on a combination of EMODnet Geology seabed substrate products and biological substrates extracted form individual habitat maps from surveys around European seas. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north. The layer of seabed substrate was produced using data from EMODnet geology at the following scales: - 1:5k, 1:10k, 1:15k, 1:20k, 1:25k, 1:50k, 1:100k, 1:200k, 1:1M (these were all update in 2023) Biological substrates were included in the 2023 version of EUSeaMap to assist in the classification of biogenic habitats for the 2019 version of EUNIS. The Folk 5 classification of substrate is adopted because it is compatible with both the 2007-11 and 2019 versions of EUNIS, both of which have been applied in EUSeaMap 2023. A report on the methods used in the 2023 version of EUSeaMap and reports on previous versions (v2019 and V2021) are linked in Online Resources.
