[18. January 2024]  Climate change will likely affect the spread of pathogens in the ocean: as water temperatures rise, bacteria that are harmful to humans could also appear en masse, posing a biological hazard. The new joint project PrimePrevention, coordinated by the Alfred Wegener Institute, has set itself the goal of developing new tools to help make society more aware of these hazards and prevent or mitigate their adverse effects.

[29. November 2023]  Yesterday evening, the research vessel Polarstern set off from Cape Town for a special region: Two expeditions in East Antarctica will focus on the history of the instability of the ice sheet there and its interactions with ocean circulation. On the first leg, which will last around two months and be led by GEOMAR, the main focus will be on oceanographic, geoscientific and biological work; the second leg will be led by Kiel University and will have a geoscientific focus, with researchers from the Alfred Wegener Institute involved in both expeditions. The change of personnel and ship supply will take place in Hobart at the beginning of February. On the occasion of the Polarstern’s first call in an Australian harbour, an exchange with representatives from science and…

[13. November 2023]  Invasive species like the Chinese mitten crab (Eriocheir sinensis), introduced roughly 100 years ago, pose a threat to native ecosystems and can do enormous ecological and economic harm. In its latest report, released just a few weeks ago, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) once again highlighted the lack of internationally coordinated strategies to combat invasive species. The Alfred Wegener Institute (AWI) and Dresden University of Technology (TUD), together with partners from Belgium, France and Sweden, have now launched the European project “Clancy”. Its goal: to markedly reduce the mitten crab population in European rivers, improving their ecological status in the process.

[08. November 2023]  Am 16. November bricht ein internationales Team von Forschenden und Bohrfachleuten von Christchurch (Neuseeland) aus in die Antarktis auf, um unter dem inneren Ross-Schelfeis bis zu 200 Meter in den Meeresboden zu bohren. Das Team will geologische Aufzeichnungen über sich verändernde Ablagerungen gewinnen, welche die Umweltbedingungen zum Zeitpunkt ihrer Entstehung in einer wärmeren Welt als heute widerspiegeln. Die Hoffnung ist, dass diese Aufzeichnungen wichtige Erkenntnisse über die Vergangenheit der Westantarktis liefern und wir so mehr über den potenziellen zukünftigen Beitrag der Antarktis zum Anstieg des Meeresspiegels erfahren.

[06. November 2023]  Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. A team led by the physicist Thomas Laepple from the Alfred Wegener Institute in Potsdam and the climatologist Kira Rehfeld from the University of Tübingen has therefore brought together experts in climate models and climate tracks to clarify how the discrepancies come about. The surprising result has now been published in the journal Nature Geoscience: in a way, both sides are right. Climate models correctly simulate global temperature trends, but often underestimate the strength of regional climate fluctuations, especially over the course of decades to centuries.
