The Arctic is changing rapidly due to climate change. It is not only affected by increasing surface temperatures, but also by warm water from the Atlantic, which is flowing in more and more – changing the structures and functions of the ecosystem as it also leads to species from warmer regions, like jellyfish, arriving in the Arctic. Using DNA metabarcoding, researchers from the Alfred Wegener Institute have now been able to prove for the first time that these jellyfish serve as food for amphipods on Svalbard during the polar night and thus play a…

A geological research team found an unusual row of stones almost a kilometre long at the bottom of Mecklenburg Bay during a student excursion in 2021. The site is located around ten kilometres off Rerik in 21 metres of water. Analyses suggest that Ice Age hunters built this structure around 11,000 years ago to hunt reindeer. It is the first time that such a hunting structure has been discovered in the Baltic Sea region, the group, with the participation of the Alfred Wegener Institute, now reports in the scientific journal Proceedings of the National…

Antarctic krill is only slightly contaminated with microplastics and is therefore well suited for monitoring the contamination of the Southern Ocean with microplastics. This is shown by a study in which researchers analysed the stomachs of the widespread shrimp species. In the journal Science of the Total Environment, the team led by the Alfred Wegener Institute warns against false positive results if extraction steps are omitted during sample preparation.

The North East Greenland Ice Stream transports enormous amounts of ice from the heart of the island to the sea and thus also influences global sea levels. An international research team led by the Alfred Wegener Institute has now used a new evaluation method for airborne radar measurements to determine the age of the icy conveyor belt. According to the study, it only extended into the heart of Greenland around 2,000 years ago. The study, which opens up new possibilities for research into ice sheets, was recently published in the scientific journal Nature…

The new research project YESSS - Year-round EcoSystem Study on Svalbard - is focussing on how Arctic warming is changing over the seasons in Svalbard. The team of around 30 scientists observes the life cycles, foraging and overwintering strategies of selected key species all year round and conducts experiments at the AWIPEV station on Svalbard. The Federal Ministry of Education and Research is funding the project, which is coordinated by the Alfred Wegener Institute, with 2.7 million euros until the end of 2026.

A new study investigating summer marine heatwaves in the Northeast Pacific Ocean projects that they may become even more intense and longer-lasting than expected by long-term warming. This could have serious implications for marine ecosystems and fishery economics. The study was recently published in the journal Communications Earth & Environment by scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).

AWI archivist Dr. Christian Salewski had a special encounter this week: Camilla-Louise Past and Julius-Alexander Past, the great-great-great-niece and great-great-great-nephew of Georg von Neumayer, the German polar explorer and namesake of the Neumayer III Antarctic station, visited the AWI Bremerhaven. They brought with them a documentary legacy, including a large-format portrait of Georg von Neumayer and a draft of a poem "Lob der Mathematik" from around 1847. The documents will now become part of the holdings of the Archive for German Polar Research.

She has been travelling in the Arctic and Antarctic in the service of research for over 40 years, but there are still areas that are new territory even for the Polarstern: Between two expeditions to East Antarctica, the Alfred Wegener Institute's research icebreaker reached Hobart in Tasmania on 30 January 2024 and will remain there until 6 February. The German Embassy in Australia, together with the Federal Ministry of Education and Research and the AWI, is inviting representatives from politics, science and society to a celebratory reception on board…

Around Christmas 2023, Germany was flooded in many places. The Elbe also reached a critical level. Now, scientists from UFZ, HEREON, GEOMAR and AWI have mobilised on short notice to investigate how the flood affects the transport of pollutants and nutrients as well as the ecosystems from the Elbe to the German Bight. The operational plan for such a flood event was already in the drawer for several years, but now it had to be executed rapidly during the Christmas holidays.

AWI Director Antje Boetius took part in the event "New perspectives for Franco-German cooperation in the Indo-Pacific region" in Paris yesterday. Together with Gerald Haug, President of the German National Academy of Sciences Leopoldina and Director at the Max Planck Institute for Chemistry, and Olivier Poivre d'Arvor, Ambassador for Polar and Marine Affairs at the French Ministry of Foreign Affairs, she discussed ways of expanding cooperation in the Indo-Pacific region, which is becoming increasingly strategically important for both countries.
