Seabed Habitats

Move toolbar
This is a free resource for viewing and downloading seabed habitat data in European waters. It contains a collection of habitat maps and point data from surveys, a broad-scale habitat map for all of Europe (known as EUSeaMap) and layers showing environmental variables known to influence habitat distribution.



To view the layers on your desktop GIS application or another web mapping portal without download, you can use our web services.

Before using this site, please read the EMODnet Seabed Habitats webGIS Terms and Conditions and Privacy Policy.
