EUSeaMap (2023) Broad-Scale Predictive Habitat Map for the Caspian - Substrate type (a habitat descriptor)
Description
Classified seabed substrate types for European seas. Produced by EMODnet Seabed Habitats as an input layer for the 2023 EUSeaMap broad-scale habitat model for the Caspian region, 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 Caspian sea. The layer of seabed substrate was produced using data from EMODnet geology at the following scales: 1:10k, 1:500k, 1:1m, 1:5m (updated in 2023).
The seabed substrate include:
Rock and other hard substrata
Coarse substrate
Mixed sediment
Sand
Muddy Sand
Sandy Mud
Mud
Bottoms dominated by Mytilaster lineatus and Amphibalanus improvisus
Bottoms dominated by Dreissena grimmi
Biological substrates were included in the 2023 version of EUSeaMap to assist in the classification of biogenic habitats. A bespoke classification of benthic broad habitat types was developed as part of EMODnet Seabed Habitats.
