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

ice conditions in the main export pathway of Arctic sea ice, the Fram Strait, and in the Lincoln Sea delivering the thickest ice to Fram Strait. Based on measurement data we will determine sea ice thickness
