Baltic circalittoral mixed sediment dominated by Ascidiacea

Baltic circalittoral bottoms in the aphotic zone with at least 10- 90 % coverage of hard (rock/boulders/stone) and 10-90 % soft substrata (e.g. muddy/coarse sediment/sand). Epibenthic chordates cover at least 10 % of the seabed, and more than other perennial attached erect groups. Out of the epibenthic chordates, sea squirts 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. $$$Characteristic species $$$Ascidiacea: Dendrodoa grossularia, Molgula spp$$$Geographic range$$$(Kattegat) and Belt Sea
