MOSAiC Expedition
The grand finale to the expedition of a century
After more than a year in the Central Arctic, this Monday, 12 October, the research icebreaker Polarstern returned to her homeport in Bremerhaven. Accompanied by a ‘welcome committee’ of ships that came to greet, the ship entered the North Lock with the morning high tide, at ca. 9:00 am.
Sea Ice
Sea-ice extent in the Arctic at a historical low
The Arctic sea-ice extent is the lowest it’s ever been in July since the beginning of satellite observation. The sea-ice retreat is especially pronounced off the Siberian coast, as a result of which the Northeast Passage (also referred to as the Northern Sea Route) was ice-free by mid-July.

The latest findings on the MOSAiC floe
The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018. Sediments, and even small pebbles and bivalves, were incorporated into the ice during the freezing process, which the on-going melting process has brought to light on the surface of the MOSAiC floe.
