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.

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.

Our project will strongly enhance the climate models capability to represent Arctic processes that are known to be critical for simulating linkages between the Arctic and mid [...] navigability of Northern sea route over the Arctic Ocean, wildfires and changes in vegetation characteristics over Russia.

Arctic Ocean
On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, [...] these coastal waters. As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of [...] current issue of the online journal Scientific Reports. Although this interaction between methane, ocean and ice has a significant influence on climate change, to date it has not been reflected in climate

In addition, more warm and salty [...] regional climate model for the Arctic. The model consists of several components: the atmosphere, sea ice, ocean and land. Simulations with this model help us interpret the Arctic climate, its variability and [...] climate changes in the Arctic are connected to the weather and climate in central Europe. The difficult thing about these interactions is the fact that, in addition to the Arctic factors, other aspects
