Ziel der Reise / Objectives of Cruise:

Within the 3 geographical areas (Darss Rise, Belt of Fehmarn and Kiel Bight) at 4 days sampling by van Veen grab and dredge were carried out. The cruise was used to investigate the macrozoobenthos of these geographical areas at distinct vertical depth horizonts. At 27 stations the macrozoobenthos were investigated by routine benthic programme. At each station 3 van Veen grabs, 1 dredge and video imaging were used. The aim of this study was the assessment of the recolonisation potential of different water depth after long-term oxygen demands. Each depth zone and each geographical area harbour specific species inventory. Especially the zone between 15 and 20 m seem to be very important after extinction processes due to low oxygen because thes zone have enough salinity for a lot of marine species and were not or not so strong effected by these events. The results should contribute to our knowledge on recolonisation processes in the southern Baltic Sea after natural or man induced oxygen depressions (e.g. by biomass accumulation by wind mill farms).
