Marine Pollution
Working in the Arctic Fram Strait, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have found microplastic throughout the water column [...] explanation for this high level of pollution. According to their findings, the two main ocean currents in Fram Strait transport the microscopically small plastic particles into the region between Greenland and

in the past, was densely covered with ice, including multiyear ice. The journey from the northern Fram Strait to the Pole only took six days to complete. To mark this momentous event, countless members

Arctic Expedition
On Whit Monday, 24 May 2021, the Polarstern will set sail for the Arctic. In Fram Strait, between Greenland and Svalbard, more than 50 participating scientists will resume the long-term

indispensable “single punishment” on Pentecost Monday, May 24, and set sail for our expedition to the Fram Strait, the passage between Greenland and Spitsbergen.
