Summary
The maximum of POC in the surface layer (200–400 μg·l−1) followed the retreating ice from end November to end December. In the upper 150 m DOC amounted to 10–20 times the POC content. Free floating sediment traps at 150 m showed a daily sedimentation of 0.6–11.6% of the standing stock of POC, 0.1–2.6% of the chlorophyll-a and 5–190% of the gross primary production. Maximum sedimentation occurred during grazing of a krill swarm, indicating the important role of krill swarms in the downward flux. Also at most other stations krill faecal strings formed a large part of the downward flux.
Data presented here were collected during the European Polarstern Study (EPOS) sponsored by the European Science Foundation
