Arctic Circle: A virtual talk about the largest Arctic research expedition of all time: AWI Director Antje Boetius and MOSAiC expedition leader Markus Rex talk about the MOSAiC expedition at "Arctic Circle virtual". The event will take place online on October 27th from 1 p.m. More information.

A whole day around the MOSAiC expedition: At the Futurium in Berlin, AWI scientists reported on their experiences on the MOSAiC expedition in the Arctic. During a panel discussion, expedition leader Markus Rex, AWI director Antje Boetius and director Philipp Grieß also showed impressive photos of the expedition. The interview is available online.

During the last 2.6 million years of Earth’s climate has alterd between glacial and interglacial states. As such, there have been times in which the transition between the two climate states appeared with either regular or irregular periodicity. AWI researcher Peter Köhler has now discovered that the irregular appearance of interglacials has been more frequent than previously thought. His study makes a significant contribution to our understanding of Earth’s fundamental climate changes.

Over the past three decades, the depths of the Antarctic Weddell Sea have warmed five times faster than the rest of the ocean at depths exceeding 2,000 metres. This was the main finding of an article just published by oceanographers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). In the article, they analyse an unprecedented oceanographic time series from the Weddell Sea and show that the warming of the polar depths is chiefly due to changed winds and currents above and in the Southern Ocean. In addition, the…

Krill is rapidly gaining popularity. The small shrimp-like organism from the Antarctic is used as fish food in aquaculture and increasingly in dietary supplements and healing ointments. Although the krill catch is regulated, caution is required to avoid endangering the population itself and the species that depend on it, warns a group of krill experts headed by Prof. Dr. Bettina Meyer from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in the journal Communications Earth & Environment - Nature. 

Professor Hans-Otto Pörtner, AWI scientist and member of the Intergovernmental Panel on Climate Change (IPCC), has been appointed member of the German Advisory Council on Global Change (WBGU). The Advisory Council acts as an independent scientific advisory body and analyses global environment and development problems, evaluates global sustainability policy and makes recommendations for action and research. See WBGU press release.

After more than a year in the Central Arctic, this Monday, 12 October, the research icebreaker Polarstern returned to her homeport in Bremerhaven. Accompanied by a ‘welcome committee’ of ships that came to greet, the ship entered the North Lock with the morning high tide, at ca. 9:00 am. At port, Expedition Leader Markus Rex, Captain Thomas Wunderlich and the entire team from the final leg of the expedition were welcomed by e.g. Federal Minister of Research Anja Karliczek and the Director of the Alfred Wegener Institute, Antje Boetius. The event marked…

The Alfred Wegener Institute comments on the latest reports in the media and social networks about alleged equality and diversity problems in connection with the MOSAiC expedition.

EU4Ocean: The new EU network on marine protection was launched with the workshop "Designing Ocean Literacy action in Europe" as a kick-off event. The EU4Ocean Platform, consisting of 76 organisations and initiatives, presented concrete ideas for global marine protection for the first time at the virtual event. AWI is also a member and was represented at the event by Gesche Krause.

The severe droughts in the USA and Australia are the first sign that the tropics, and their warm temperatures, are apparently expanding in the wake of climate change. But until now, scientists have been unable to conclusively explain the reasons for this, because they were mostly focusing on atmospheric processes. Now, experts at the AWI have solved the puzzle: the alarming expansion of the tropics is not caused by processes in the atmosphere, but quite simply by warming subtropical ocean.
