l research team is now bringing back from a Polarstern expedition to the Central Arctic. After a four-month-long Arctic season, the Alfred Wegener Institute’s research icebreaker is expected to arrive

result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. A new study published in the journal Geophysical Research Letters now shows that large amounts [...] of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.

show, part of the biomass released becomes trapped in deep sinks on the ocean floor off the Arctic coast – where it is protected from microbial decomposition. The outcomes of their analyses are intended [...] Permafrost
The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once [...] Once eroded material is released into the ocean, microorganisms break down ancient plant remains, releasing sizable quantities of greenhouse gases. Yet, as the latest analyses conducted by AWI experts show

Agreement is not achieved. Under conditions of further warming and acidification of the ocean, Atlantic cod and its arctic relative polar cod would be forced to look for new habitats in the far north. Their [...] dwindle. If so, this could be disastrous, as the polar cod is the most important food source for Arctic seals and seabirds. In addition, fishers could lose the world’s most productive area for catching

Arctic cod is the most abundant fish in the Arctic Ocean. It is an important food source for Arctic marine mammals and plays an important role in the self-sufficiency of the Inuit. An international study [...] now evaluated the most important scientific work on Arctic cod of the past decades. The conclusion: Above all, the already advanced decline in arctic sea ice cover as a result of man-made climate change

Anniversary
40 years of research in the Arctic, Antarctic and in coastal regions: on 15 July, the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) celebrates its 40 th [...] and internationally recognised centre for climate research in the two polar regions and the world’s oceans.

Arctic Ocean
This summer the sea-ice cover on the Arctic Ocean shrank to the second-smallest extent since the beginning of satellite observation in 1979. By mid-September it covered only 3.8 million [...] formed in Russia’s marginal seas, and soon melted again when the spring came. Secondly, this year the Arctic has seen extremely high air and water temperatures. Accordingly, heat gnawed away at the ice from

Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent their [...] recently demonstrated. If this comes to pass, it could have far-reaching consequences for life in the ocean, as they report in the journal Nature.
