During PS93.2 (in 2014) taxa specific macrofauna biomass was determined. Sediment from MUC recovered sediment cores and from the benthic chambers was used for macrofauna taxonomical identification and biomass determination. For these macrofauna analyses only the 0-5 cm horizon from MUC sediment cores and the entire sediment from the benthic chambers was used, sieved over a 500 µm mesh and stored in borax buffered 4 % formaldehyde and stained with Rose Bengal (Heip et al., 1985). Afterwards, macrofauna taxa were identified to the highest taxonomic level and weighted (blotted wet weight). ...
