Ziel der Reise / Objectives of Cruise:

PS112: Three third-party-funded projects dominated the expedition: The KrillBIS project (Krill stock assesment in the Southern Ocean) determined the study region representing the German research contribution to CCAMLR (Commission for the Conservation of Antarctic Living Resources). This target region, where krill and salp abundances were investigated using net tows and hydro acoustic techniques, was the East and West Bransfield Strait, the area North of the South Shetland Islands, the area around Elephant Island, and the area East of the Antarctic Peninsula, Erebus and Terror Gulf as well as the Antarctic Sound. Four process studies in this region (one around Deception Island, two around Elephant Island and one in the Erebus and Terror Gulf) were focussing on the other two third-party funded projects, completed the krill/salp directed research programme. One project is the POSER (Population Shift and Ecosystem Response) project funded by the Lower Saxony Ministry of Science and Culture (MWK). The third project is the PEKRIS (The performance of Krill vs. Salps to withstand in a warming ocean) project supported by the Federal Ministry for Education and Research (BMBF). POSER deals with the interaction between salps and krill and their influence on the biological carbon pump, as well as the phytoplankton community and the recycling of the trace metal iron, which is essential for phytoplankton growth. The PEKRIS project on the other hand investigates the plasticity of krill and salps under increasing ocean temperatures.
