A combination of multiple stressors reduces the acclimation potential of Atlantic herring larvae. A recent study shows that an increased temperatures and bacterial exposure together impair the larval stress response. The outcomes of the study highlight the high sensitivity of herring early life stages towards multiple climate change-related stressors. The study was published in the journal Science of the Total Environment by scientists from the Helmholtz Institute for Functional Marine Biodiversity at the University of Oldenburg (HIFMB), the Alfred…

In spring 2025, the Director of the Alfred Wegener Institute, Prof Antje Boetius, will be appointed president of the Monterey Bay Aquarium Research Institute (MBARI) in California. MBARI is one of the most esteemed institutes for marine research and technologies. Based on the US Pacific Coast, it specializes in exploring the deep sea and its unknown diversity of life. “This position will give me a unique opportunity to contribute to the development of innovative deep-sea technologies with a focus on imaging, robotics, sensor systems and AI,” says the…

National and international water policy must adapt to ongoing, accelerated changes in the global water cycle and respond to them quickly and comprehensively. This is the key message of the WBGU report 'Water in a heated world', which the German Advisory Council on Global Change (WBGU) today presented to Federal Environment Minister Steffi Lemke and the Parliamentary State Secretary in the Federal Ministry of Education and Research, Mario Brandenburg.

The Arctic is a key region for global environmental changes and developments in security policy that also concern Germany. In the following, Dr Volker Rachold, head of the Arctic Office at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), explains why the federal government has updated its Arctic policy guidelines in view of the rapid climate warming and geopolitical changes like the Russian war of aggression against Ukraine. On 18 October, these revised guidelines – which the Arctic Office contributed to – will be…

Nitrogen fixation in ocean eddies is an important component of the local nitrogen cycle in the western North Atlantic. In addition to local environmental conditions, the transport of nitrogen fixers from the more productive Mid Atlantic Bight to the nutrient-poor Atlantic Subtropical Gyre also promotes this process. This is one of the results published by researchers from the Alfred Wegener Institute together with international experts in the journal Nature Geoscience. To the publication

Sparse sea ice, thousands of datapoints and samples, a surprising number of animals and hydrothermal vents – those are the impressions and outcomes that an international 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 back in Bremerhaven with the morning high tide on Sunday. 

Toxic trace elements such as lead, mercury, arsenic, and cadmium naturally occur in small quantities in coastal seas. However, human activities, such as industry and agriculture, contribute significantly larger amounts. A new study has examined how climate change already affects the distribution and accumulation of these elements and how it could impact them in the future. One of the findings: Climate-related natural events are releasing more contaminants, which pose a risk to both human and animal health. However, there is still insufficient knowledge…

Tabea Rettelbach, PhD student at the AWI, is one of two winners of this year's Bernd Rendel Prize. Her work focuses on the topic of "Permafrost". The Bernd Rendel Prize is awarded annually by the German Research Foundation (DFG) to outstanding young scientists in the geosciences. The award ceremony took place during the annual conference of the German Geological Society - Geological Association (DGGV) from 23 to 26 September in Dresden.

Who are the 100 key figures on the German science scene? Research.Table has selected AWI Director Antje Boetius as one of the leading personalities in the “Science” category. The award recognises her significant contributions to the exploration of the polar regions and the oceans. These areas of research are crucial for understanding climate change and the global environment.

In a new two-part ZDF documentary series, AWI Director Antje Boetius gets to the bottom of the secret of our species' success story and travels to places where researchers are searching for solutions for a future worth living. Both parts are available in the ZDF media library and will be broadcast on television on 29 September and 6 October at 7.30 pm. More Information.
