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 [...] the Royal Norwegian Embassy, was ‘The sustainable future of our oceans’. AWI Director Antje Boetius moderated the event.

Arctic Ocean
The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for

conduct studies at a major long-term monitoring station in the Arctic: the AWI’s Hausgarten observatory in the Fram Strait, where experts from various disciplines are investigating all aspects of the ecosystem, from the water’s surface to the ocean depths, in order to determine the impacts of climate change on biodiversity in the Arctic. After roughly a month underway, in [...] one-year-long MOSAiC expedition, prior to leaving for the Central Arctic on 20 September.

Arctic Sea Ice
The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by sea ice any more, according to researchers from the Alfred Wegener Institute and the University of Bremen. This

On board researchers will investigate a region that is virtually inaccessible in winter, and which is crucial for the global climate [...] urgently needed data on the interactions between the atmosphere, ocean and sea ice, as well as on the ecosystem. Thanks to the collaboration between international experts, the one-year-long ice drift

Polarstern Expedition
Under the ice of the Arctic, unknown habitats conceal an unexpected variety of living beings. On October 23rd, 46 scientists are expected to return to the home port in Bremerhaven from an Arctic expedition with the research vessel Polarstern. Over the past six weeks, they had explored life in ice, ocean and seabed with new

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 [...] for thousands of years. 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 [...] 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 to make

Arctic
The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged
