ecology with the global climate through plankton productivity and particle sedimentation to the deep ocean, a process known as the Biological Pump, and the diversity and ecophysiology of key polar organisms [...] biology and ecology We explore the biology of polar plankton, its role in the ecology of the Polar Oceans as well as its efficiency in stimulating the biological pump which is, in fact, mitigating the greenhouse [...] Research groups: Ecophysiology of pelagic key specie s Phytoplankton ecology & particle flux in the Arctic Arktic zooplankton Marine Chronobiology Biodiversity Image analysis as well as molecular measurement

Double-Trouble Resilience and vulnerability of the central Arctic Ocean food web to cumulative stress by warming and anthropogenic pollution. Head of Group Dr. Doreen Kohlbach Further members of the Junior [...] for polar marine food webs. Previous research suggests that pelagic food webs in the Central Arctic Ocean (CAO) are highly dependent on ice-associated food sources (Fig. 1), but how prevailing trophic [...] waters, riverine input and marine traffic will bring more anthropogenic pollutants, even to remote Arctic regions, where they are entrained in water and sea ice, and transferred along the marine food chain
