Central research questions included how the ice conditions, ocean heat fluxes and ocean stratification determine sea-ice [...] 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

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 [...] zone, the team of researchers on board will investigate how heat fluxes and water layering in the ocean, as well as the characteristics of the ice, interact and influence melting.
