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
