During the return journey of an Antarctic expedition in the Bellingshausen Sea geoscientist Johann Klages threw a message in a bottle into the water. He has now received an email from Tasmania: Toby Ray found the bottle on the west coast of Tasmania - it has travelled around two-thirds of Antarctica

Brilliant to see this paper rdcu.be/eUWMI by @NEGIS_Durham team & led by @louisecallard.bsky.social Work offshore with partners @awi.de revealing how ocean warming triggered ice shelf collapse @geogdurham.bsky.social @ncl-geography.bsky.social
Ocean driven retreat of the Northeast Greenland Ice Stream following the Last Glacial Maximum
Nature Communications - Warm Atlantic Water was a major driver of both initial NEGIS retreat from 21.6 ka BP and the collapse of its ice shelf ~15.2 ka BP. This study demonstrates the key role of...

AWI researchers are studying whale songs with the help of AI. The result: bowhead whales appear to reproduce under the sea ice northwest of Spitsbergen, while using the open water in the eastern Fram Strait as a migration route. 🐋

🪸Good morning from @awi.de HAUSGARTEN observatory in the #Arctic #DeepSea. This photo taken by our Ocean Floor Observation Bathymetry System (~2500 m) shows sponges (Caulophacus arcticus, Cladorhiza gelida) with a comatulid, anemones, soft corals (Gersemia fruticosa) & shrimp (Bythocaris) on them!

The Beyond EPICA project begins the fifth and final drilling campaign in Antarctica. AWI researchers are part of the international research team that will drill into the bedrock beneath the Antarctic ice sheet – at an altitude of 3,200 meters above sea level and temperatures around -35°C.

Our research vessel Polarstern is back in Bremerhaven after a long journey. ⚓️❤️

During the expedition, researchers took measurements in the seawater north of Greenland. Initial results show that there is a current band that transports warm Atlantic water from the Arctic Ocean southward. 🌊

AWI climate researcher Markus Rex receives the NOMIS Award 2025. 🏆👏

The award recognizes his leadership of the MOSAiC expedition, in which scientists from 20 countries researched the interaction between ice, ocean, atmosphere, and ecosystem in the Arctic.

A hydrothermal vent on the Mid-Atlantic Ridge. Hot, mineral-rich fluids are distributed throughout the ocean via the dispersion cloud, known as the plume. The photo was taken during the M190 research expedition with the MARUM-QUEST4000 remotely operated vehicle. The arm of the robot holds a temperature lance into the plume to measure the temperature there. Photo: MARUM – Center for Marine Environmental Sciences, University of Bremen.

🐧 Is #Antarctica trying to talk to us?

As warming temperatures chip away at the continent’s ice shelves, #WHOI scientists are listening for signs of unstable ice using acoustic data collected by the @awi.de

AWI researchers have mapped 19,000 driftwood in Alaska and northwestern Canada for the first time.
The data will help to better understand coastal processes, carbon storage and environmental changes such as storm surges and erosion.

The heart of the new Polarstern ❤️🚢

Together with our shipyard TKMS, we have reached a milestone in the construction of the new Polarstern: the new propulsion unit for the icebreaker has been finalized and the corresponding contracts have been signed.

Can you spot the Polarstern amid the ice floes of the Arctic? 🧊A satellite image shows, that we are just a pixel amidst ice floes (light grey) and open water (dark). Polarstern appears as a bright spot in the image because it reflects electromagnetic radiation more strongly than its surroundings.

Unique concept for observing Arctic sea ice successfully implemented: AWI scientists were able to study different types of sea ice in parallel during the Polarstern expedition “CONTRASTS.” 🧊
