will focus on extended ecological fieldwork at the AWI’s deep-sea observatory Hausgarten and at the FRAM Ocean Observing System between Greenland and Svalbard. 50 researchers and a ship’s crew of 24 will

collect on our regular ship-based expeditions. Our expeditions mainly take us to three focus regions: Fram Strait between Greenland and Svalbard, the Eurasian sector of the Arctic Ocean, and the Weddell Sea
