AWI researchers have reorganized the Global Terrestrial Network for Permafrost (GTN-P) database and made it publicly accessible. Since the 1990s, the GTN-P has collected high-quality data to monitor global permafrost changes and its role in the climate system.

In 2025, the AWI and University of Bremen secured extensive data sets from the USA. Now, the @dfg.de has approved around €860,000 in funding to systematically identify endangered data and secure it for the long term with the help of the PANGAEA data platform. ☁️📊

Happy new year to Antarctica @alexandrazuhr.bsky.social from @unituebingen.bsky.social! Work near Kohnen station is progressing well. All 979 (!) stake readings for surface mass balance are done and up next are flights with @awi.de’s UWBm radar. Has snowfall increased in the last decade?

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

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. 🐋

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. 🌊
