Sea Ice
The Arctic sea ice continues to dwindle: Since the 1970s, when satellites first began monitoring the white sheet covering the Arctic Ocean, its February extent was never as small as it was this [...] this year. The reason: warm air intrusions, which are not only hitting the Arctic more frequently, but are also intensifying and reaching farther north.

German Norwegian Ocean Forum
From the Arctic to the North Sea: this year’s German Norwegian Ocean Forum was held in Bremen’s Übersee Museum. The spotlight topic of the symposium, which was jointly organised [...] by the AWI, Innovation Norway, and the Royal Norwegian Embassy, was ‘The sustainable future of our oceans’. AWI Director Antje Boetius moderated the event.
