The German Arctic Office has compiled an analysis on the Security Policy in the Arctic, including contributions from the German Foreign Office, the German Ministry of Defense, and the German Institute for International and Security Affairs. With climate change, valuable resources are becoming accessible in the Arctic, and new shipping routes are opening up. This is rapidly changing the geopolitical situation, and interstate conflicts in the Arctic may arise. The new publication provides an outline as well as an outlook of the relevant topics here.

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 acidity has increased by nearly 30 percent since the beginning of the Industrial Revolution. In this regard, the water’s pH value isn’t constant; it varies both seasonally and regionally. The lowest values naturally occur in winter. But that could soon change, since they could be shifted to the summer by climate change, as an international team including…

Mesoscale ocean eddies are small, short-lived phenomena that effectively influence ocean properties like temperature, velocity, and salinity.  The effects of eddies are integral to ocean circulation, the uptake of heat and carbon at depth, gas exchange with the atmosphere, and the transport of nutrients. In a new study, a research team led by Alfred Wegener Institute scientists investigated what long-term impact anthropogenic climate change will have on ocean eddies and their far-reaching effects. Using climate model simulations, the study shows how…

On 9 August 2022, eleven researchers from seven countries left Bremerhaven, bound for the Arctic. On board the research ship Heincke, the RISING expedition – an initiative of the Helmholtz Young Investigator Group ARctic JELlies (ARJEL) at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) – had begun. The international team included experts from the AWI, GEOMAR and the University of Bergen. Their goal: to survey jellyfish along a poleward oriented line of latitude: from northern Norway, through the Barents Sea to the…

Over the past several decades, the Arctic has warmed much faster than the rest of the world. With consequences for its sea ice. In order to gauge the thickness of ice masses in the North Pole region, scientists chiefly rely on satellites. But this method proves problematic in the summer, when melting processes on the ice’s surface make it difficult to apply. An international team of researchers including experts from the Alfred Wegener Institute has now developed a method that, for the first time, makes it possible to identify changes in the Arctic…

ICYMARE, a conference organised by and for young marine scientists, will take place in Bremerhaven from 13-16 September. Organized entirely by volunteers, the international meeting offers the opportunity to exchange ideas with other young researchers and to build up a network at an early stage. ICYMARE is an event of the Bremen Society for Natural Sciences and will take place at the University of Applied Sciences Bremerhaven and the AWI – with many contributions from AWI young researchers.

Digitalising engineering: ELISE GmbH's mission is to harness the combined expertise of engineers and automate certain aspects of product development; in particular, it hopes to reduce the time needed for drafting, designing and constructing technical components. Investors have now provided ca. 14.5 million euros of financial backing for the Bremen-based start-up.

Many marine organisms such as brown algae, fish or bristle worms have an internal monthly calendar: They adapt their behavior and reproduction to the different light conditions to which they are exposed. A team led by the two researchers Kristin Tessmar-Raible (Alfred Wegener Institute and Max Perutz Labs Vienna) and Eva Wolf (Johannes Gutenberg University and Institute of Molecular Biology, Mainz) has now discovered how marine organisms can distinguish between different light conditions and adjust their internal calendar accordingly.

AWI Director Antje Boetius will give a talk on "Eyewitnesses Anthropocene: Expeditions to the End of the World" at the 132nd Assembly and 200th Anniversary of the Society of German Natural Scientists and Physicians (GDNÄ) on September 8, beginning at 4:30 pm. The lecture will be streamed live. In addition, AWI will present the photo exhibition on the MOSAiC expedition: "Polarnight" by Esther Horvath at the assembly.

On 6 September, the Kavli Award Ceremony will took place in Oslo, with AWI Director Antje Boetius and AWI Vice Director Uwe Nixdorf also attending. The Kavli Prize honours scientists for achievements in astrophysics, nanosciences and neurosciences and is presented to the winners by Norway's King Harald V. In addition to the award ceremony, the entire week represents a biennial celebration of science and provides opportunities for dialogue on significant research.
