MOSAiC - Multidisciplinary drifting Observatory for the Study of Arctic Climate

It was the largest-scale Arctic research expedition of all time: in September 2019 the German research icebreaker Polarstern departed from Tromsø, Norway and, once it had reached its destination, has spend a year drifting through the Arctic Ocean, trapped in the ice. A total of 600 people from 19 countries, who were supplied by other icebreakers and aircraft, participated in the expedition – and several times that number of researchers will subsequently use the data gathered to take climate and ecosystem research to the next level. The mission was spearheaded by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). More information about the expedtion here.
