Arctic plankton ecology and related sedimentary flux under climate change
The Arctcic Ocean reacts more sensitive to Gloabal Change than other oceans. Sea ice strongly decraeses, temperatures rise at least twice as much, acidification and, the influence of warmer water from the North Atlantic is increasing ('Altantification')
In order to understand and follow the changes it is essential to perform continuous observations. Since 1991 samples have been taken and analysed and more will be taken in the future mainly as part of projects such as FRAM, LTER HAUSGARTEN, PEBCAO in different regions of the Arctic Ocean. The main goal of our arctic research is to understand and follow seasonal and interannual fluctuations of particle formation, modification, and sedimentation in relation 1) to the environment and changes therein, 2) to changes in key species performances and, 3) to changes in food web structures.
