The investigations [...] ons will focus on the differences in the melting of various sea ice types – representing the Arctic of the past decades, the present and the future.

However, jellyfish in the world’s oceans could actually benefit from the rising water temperatures – also and especially in the Arctic Ocean, as researchers from the Alfred Wegener Institute [...] Institute have now successfully shown. In computer models, they exposed eight widespread Arctic jellyfish species to rising temperatures, sea ice retreat and other changing environmental conditions. The result: [...] triple the size of its habitat – with potentially dramatic consequences for the marine food web and Arctic fish populations. The study was just released in the journal Limnology and Oceanography.

The scarcely explored region to the north of Greenland was the area of study in the last of three Arctic expeditions undertaken by the Polarstern since the end of May 2025. In the largely untraveled waters [...] oceanographer Torsten Kanzow of the Alfred Wegener Institute were able to collect unique data on ocean circulation in the area. A chain of six moorings was also deployed to conduct autonomous measurements

Ocean Eddies
In a new study, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated the long-term changes in the Arctic Ocean eddy activity [...] study reveals a remarkable surge in Arctic eddy activity in a warmer climate, a trend that is probably unparalleled when compared to other regions across the global ocean.
