Strong sea-ice drift for MOSAiC in 2020

Following in the footsteps of Nansen and his Fram expedition more than one hundred years ago, the research vessel Polarstern has been frozen into the ice since October, and drifts in the Arctic Ocean towards Svalbard and the Fram Strait. This international expedition is called MOSAiC ( In 1893-1896 it took Nansen’s ship nearly three years to drift across the Arctic Ocean. For MOSAiC the journey has been less than a year.

Status of the sea-ice extents in spring 2020

The yearly maximum (in the Arctic) and minimum (in the Antarctic) sea-ice extent occurs in February/March. With satellite data processed at Norwegian Meteorological Institute the sea-ice extent is tracked and described on a daily basis.


Skiing across the Arctic Ocean on drifting ice

Børge Ousland and Mike Horn’s 87 day expedition to cross the Arctic Ocean via the North Pole on skis, from boat to boat without assistance, took place during changing sea ice conditions. Using sea ice drift products - retrieved daily from satellite data - we can estimate the influence ice drift had on the expedition.
