New dataset reveals biological “treasure trove” of Arctic Ocean
A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk. The research led by scientists from the Alfred Wegener Institute and the University of East Anglia is now published in PLOS Biology, futher informations can be found in this UAE's press release.
Polarstern Returns to Bremerhaven
The Research Vessel Polarstern was in the Arctic for the past seven weeks. There, the summertime sea-ice extent declined by ca. 40 percent over the past 40 years – making it one of the most visible impacts of climate change. In order to better grasp such changes, the research teams on board the Polarstern investigated Atlantic Water Recirculation in Fram Strait and in the marginal ice zone north of Svalbard, as well as ocean/glacier interactions off the coast of Greenland.

150 Whales Observed Feeding Together
After blue whales, fin whales are the largest whales in the world – and human beings have hunted both species to near-extinction. After the ban on commercial whaling in 1976, the stocks of these long-lived, but slow-growing creatures are rebounding: in the journal Scientific Reports, researchers and filmmakers jointly present videos and photos of large groups of up to 150 southern fin whales in their historical feeding areas.
