changes for the biodiversity in this area. Physical, biogeochemical and ecological studies with Polarstern in the FOS in the southern Weddell Sea shall characterize this hotspot in detail in order to recognize
North American plate drift apart by a few millimetres every year. Using the research icebreaker “POLARSTERN” scientists study this system of ridges and investigate the effects of the mechanisms involved
Important milestones have been reached in the construction of the new Polarstern. A true-to-scale model of the future research icebreaker successfully completed tests in the ice channel. This marked the
the northwestern Weddell Sea in the Antarctic on board the Alfred Wegener Institute's icebreaker Polarstern since 8 February 2026. In this key region for global ocean currents, the focus has been on the
