[10. June 2024]  The depths of the Weddell Sea are home to diverse biotic communities consisting of sponges, cold water corals, and countless other organisms. Moreover, as climate change progresses, this ice-ladden region could offer a refuge for ice-dependent algae and fauna, from krill to Weddell seals. In the new EU project WOBEC, the Alfred Wegener Institute, as the coordinator of a consortium of eleven institutions from Europe and the US, will establish the basis for systematic, long-term observations of potential changes in this unique ecosystem. The project, which has been allocated ca. 1.9 million euros of funding, will develop a strategy for monitoring changes in a Marine Protected Area (MPA) proposed by the EU and various states in the Weddell Sea. WOBEC will be based on the…

[05. June 2024]  For the past 25 years, the Alfred Wegener Institute has operated a long-term observatory in the Arctic deep sea: the HAUSGARTEN. Located between Greenland and Svalbard, it is where researchers investigate natural and climate-change-related changes in a polar, marine ecosystem – from the ocean’s surface to the seafloor, 5,500 metres below. Many of the observatory’s stations are located below the sea ice, while its autonomous systems take measurements year-round, i.e., even when left unmanned.

[04. June 2024]  Researchers around the globe are sounding the alarm: ocean temperatures are the warmest ever recorded. In 2023, the North Sea also experienced dramatic record highs, as readings taken by the Alfred Wegener Institute’s Biological Institute Helgoland indicate. As data from the time series “Helgoland Reede” also reveal: it’s not the first year in which the German Bight experienced marine heatwaves. The high temperatures and extreme weather events are a product of climate change and could have substantial impacts on the ecosystem.

[03. June 2024]  Permafrost soils store large quantities of organic carbon and are often portrayed as a critical tipping element in the Earth system, which, once global warming has reached a certain level, suddenly and globally collapses. Yet this image of a ticking timebomb, one that remains relatively quiet until, at a certain level of warming, it goes off, is a controversial one among the research community. Based on the scientific data currently available, the image is deceptive, as an international team led by the Alfred Wegener Institute has shown in a recently released study. 

[17. May 2024]  The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic, which were recently conducted at the AWI’s AWIPEV Station.
