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

Fresh water from [...] satellite remote sensing and regional airbornesea ice thickness measurements. Oceanographic moorings in Fram Strait provide estimates of liquid fresh water transport. Once validated, the models can be used for
