MOSAiC 2019/20

The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) is an international research project aimed at collecting data from the Arctic Ocean for an entire year by letting the research vessel Polarstern drift with the pack ice.

About MOSAiC

On the MOSAiC expedition, experts from 20 nations studied the Arctic for an entire year. For this purpose, from autumn 2019 to autumn 2020 the German icebreaker Polarstern drifted across the Arctic Ocean, trapped in the sea ice. MOSAiC is coordinated by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). Over 80 scientific institutes are working together in a research consortium. The expedition’s total budget is over 140 million euros.
