Ziel der Reise / Objectives of Cruise:
The cruise main objective was to study the overwintering of Antarctic krill and zooplankton. After sailing from C.T., Polarstern headed south and started surafce plankton sampling and visual vertebrate observations as soon as possible (outside 200 nm region of SA). Just inside the sea ice area Polarstern was struc by a severe storm, after which we started sampling with CTD and various plankton and krill nets along our planned transect for the Lazarev Sea Krill Study (LAKRIS). LAKRIS is aimed at providing a better understanding of the role of Krill and zooplankton in the Southern Ocean ecosystem. The regular sampling grid consited of 65 stations between 60? and 70? S, and 3? E and 3? W. At the grid stations a variety of instruments and gear was used: A CTD-sonde together with a multi-bottle water sampler, a Rectangular Midwater Trawl (RMT), a Multinet and other nets as well. Within the grid, we served one 4 day long diving station with a total of 26 dives and 955 minutes diving time. En route, current measurements were made with an ADCP and zooplankton backscatter measurements were recorded by an echosounder. When crossing the Antarctic Circumpolar Current, a continuous plankton recorder was towed.
