ME2-2 - Habitat biogénique du bathyal supérieur en Atlantique

Atlantic upper bathyal biogenic habitat

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Biogenic structures in the upper bathayl zone of the Atlantic formed when reef-forming species, such as cold water corals, attach to any hard substrate present and grow over the surrounding area forming a secondary substrate over the top. This changes the composition of the associated community as it provides a stable surface for epifauna to attach. Biogenic structure includes only areas where the seafloor is completely covered, not isolated structures, such as sponge aggregations or discrete corals.
