Biogenic substrate in European waters

Other

This layer shows the current known extent of biogenic substrate in European waters. This product was first produced in 2021 with the aim to add a new class of substrate into the EUSeaMap substrate layer. This was required in order to classify the EUSeaMap broad-scale habitat map according to the 2019 version of the EUNIS habitat classification system, which includes a biogenic substrate category. In 2023 the layer was updated to feed into an updated version of EUSeaMap. The geographic extent of this product was extended in 2023 to include jurisdictional waters (including continental shelf and claimed extended continental shelf) of EU Member States, the United Kingdom (UK) and Norway including areas in the Caribbean Sea. In 2025 the layer was updated further to include both points and polygons.
