A new overview study has now shown that wind [...] the Institute for Advanced Sustainability Studies in Potsdam, and the GEOMAR Helmholtz Centre for Ocean Research in Kiel – describes how microplastic finds its way into the atmosphere and how it is subsequently

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. A further focus of the

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

A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk. The research led by scientists
