🪸Our new paper led by Lily Böhringer is out: Benthic megafauna from @awi.de #HAUSGARTEN Observatory in the #Arctic #DeepSea went through significant changes. From 2002-2021, selected taxa populations declined ranging from 28% for crinoids to 93% for soft corals.

How do clouds form in Antarctica? ☁️
AWI researchers have conducted flight-based aerosol measurements in Antarctica for the first time in around 20 years. The aim of the campaign was to investigate the processes of cloud formation in Antarctica.

Polarstern will be departing Punta Arenas for the Weddell Sea🚢 Until April, an AWI-led team will study sea ice, ice shelves, and ocean interactions in this key climate region, where summer sea ice has declined since 2017, presumably as a result of warmer surface water.

AWI researchers have found evidence suggesting that humans may have influenced fire activity in eastern Siberia more than 5,000 years ago — earlier than previously assumed. 🔥
By analyzing charcoal particles from sediment cores, they were able to reconstruct a 10,000-year history of wildfires.

A new study by the AWI, the University of Oldenburg and the Lamont-Doherty Earth Observatory shows that changes in the West Antarctic Ice Sheet could influence algae growth, which could affect the ability of the Southern Ocean to store CO₂.

Glacier ice supplies the ocean with key nutrients. In experiments, researchers at the AWI have shown for the first time that Antarctic phytoplankton can use iron from glacier meltwater, but not iron released from groundwater.

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
