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 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.

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.” 🧊

Can the color of melt ponds reveal the sea-ice thickness below? 🧊 And can we measure this from #space? 🛰️ On the @awi.de CONTRASTS #expedition, we’re testing this with a 200+ band hyperspectral camera and co-located ice thickness measurements for a large variety of #Arctic ponds.

Our icebreaker Polarstern is currently in the Arctic, where it has met up with our polar aircraft Polar 6 for the second time. The joint measurements enable researchers to place their data in an even broader context.🧊
