Fresh water slows down oceanic conveyor belt
20. November 2024The retreat of Arctic sea ice and the melting of land ice sheets around Greenland lead to more and more freshwater flowing into the Atlantic Ocean. A recent study by AWI climate modeler Qiyun Ma provides brand new insights into how freshwater released from different regions affects and weakens the Atlantic Meridional Overturning Circulation (AMOC). The study identifies the Irminger Basin as the region most responsive to additional freshwater and as a key driver of AMOC changes. Regarding the potential slowdown of the AMOC in the future, the authors highlight that it not only has global climate implications but can also shift regional climate patterns and lead to more frequent and intense weather and climate extremes, such as droughts, floods, and cold waves in different parts of the world.

The Ocean is a Noisy Place
30. October 2024AWI Director Antje Boetius provided exciting insights into marine research at the Elbphilharmonie in Hamburg: in her performative lecture as part of the project “The Ocean is a Noisy Place” by the Hanoverian orchestra “musica assoluta”, she drew attention to the threat to the marine habitat. The program, under the direction of Thorsten Encke, combined classical and contemporary music, science and video art. Video artist cylixe and cellist Tanja Tetzlaff also took part.

Study describes hotspots in the marine nitrogen cycle
11. October 2024Nitrogen 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
