Polarstern returned to her home port of Bremerhaven with the morning tide today after a seven month Antarctic expedition and is now being unloaded. The ship will spend the next few weeks at Lloyd Werft for routine maintenance and repairs before departing for the Arctic again at the end of May.

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

Today, the research vessel Polarstern will depart on a seven-week-long voyage to the Arctic, where the onset of summer also marks the beginning of the annual sea-ice melting. Over the past 40 years, the
