There is a great diversity of seabed habitats, with over 1.000 different habitat types identified across Europe’s regional seas. These vary from the coral reefs found in the cold, dark depths of the North-east Atlantic Ocean to the seagrass meadows found in coastal waters throughout Europe’s seas. Seabed habitats are impacted by a wide range of land- and sea-based human activities ranging from the effects of eutrophication in coastal areas or to extensive bottom trawling in off shore areas.
