9 December 2022 marks the 40 th anniversary of the research icebreaker Polarstern’s commissioning. Built by a consortium combining the shipyards Howaldtswerke-Deutsche Werft in Kiel and Werft Nobiskrug [...] temporary home for thousands of researchers from Germany and around the globe. In the process, the Polarstern has safely traversed 1.8 million nautical miles. The ship is currently on an expedition in the

The Research Vessel Polarstern was in the Arctic for the past seven weeks. There, the summertime sea-ice extent declined by ca. 40 percent over the past 40 years – making it one of the most visible impacts [...] impacts of climate change. In order to better grasp such changes, the research teams on board the Polarstern investigated Atlantic Water Recirculation in Fram Strait and in the marginal ice zone north of
