In the Arctic, the environments that select different [...] of sea-ice on Arctic marine single-cell eukaroyte community composition, or of ocean warming in Eastern Fram Strait since the year 2000.

observation of ice, ocean and seafloor processes in the Central Arctic. A main aim is to observe and analyse the changes in the sea ice cover, and its causes and consequences for ocean and life.

More melt water is entering the Artic Ocean from the glaciers due to climbing temperatures. In addition, the rivers are carrying large amounts of sediment from thawing permafrost. How the [...] the Arctic Ocean will react to such changes is a very big question, which is concerning scientists around the world. Researchers from the Alfred Wegener Institute have now published, together with int

Algae that live in and under the sea ice play a much greater role for the Arctic food web than previously assumed. In a new study, biologists of the Alfred Wegener Institute, Helmholtz Centre

This September, the Arctic sea ice extent has shrunk to 4.1 million square kilometres (sq km)-the second lowest in the history of satellite measurements. It is exceeded only by the all-time [...] all-time record low of 3.4 million sq km in 2012.
