Arctic Ocean

The Pulse of Heat in the North Atlantic

The future of the Arctic Ocean will be decided in part in the Fram Strait, a region between Greenland and Svalbard in which warm water flows northward from the Atlantic. The AWI is investigating just how much of that water actually reaches the Arctic
Tiny algae, hugely resilient

Microalgae are microscopically small, single-celled algae species and an important source of food in the oceans. AWI researchers examines how changed living conditions as a result of climate change affect Arctic microalgae
Uncharted territory!

The ice shield of Greenland is shrinking – at an ever faster rate. To understand why AWI researchers had to take the Polarstern where no other research vessel had ever been – directly to the glacier front. An expedition report

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.

Bivalve ice with pebbles

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.
