Baltic offshore circalittoral mixed bottoms characterized dominated by barnacles (Balanidae)
Description (English)
Baltic offshore bottoms in the aphotic zone, below halocline/pycnoclinewith at least 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Epibenthic crustacea cover at least 10 % of the seabed, and more than other perennial attached erect groups. Out of the epibenthic crustacean, barnacles constitute at least 50 % of the biomass.
Physical environment
Substrate is soft or crystalline rock, boulders or stones mixed with mobile substrates such as sand or coarse substrate. Depth is typically from 20 to 100 meters. Appears in all wave exposure classes. Salinity >3 psu.
