Baltic offshore circalittoral rock and boulders characterized by sparse epibenthic macrocommunity

Description (English)

Baltic offshore bottoms in the aphotic zone, below halocline/pycnocline with at least 90 % coverage of rock, boulders or stones of more than 63 mm in diameter. Sessile/semi-sessile epibenthic fauna is present but covers less than 10 % of the seabed.
