starting in summer 2026. Before this, different test campaigns are planned, including a shorter drift in Fram Strait in summer 2025 and winter experiments in Svalbard. Tara Polar Station in Lorient, France, in

aircraft crews. Tue, 20 June Weather conditions were favourable for a boundary layer flight over the Fram Strait under north-westerly wind conditions. It was interesting to observe that the boundary layer [...] boundary layer in a region of roughly 120 km times 30 km over a still sea ice covered part of the Fram Strait. The flight was very successful, the data look promising. Wed, 21 June A visit on RV Polarstern [...] very lucky in this regard. We suppose that one reason for the large sea ice cover in the Northern Fram Strait during the entire campaign was the prevailing northerly winds. Collocation with Polarstern

INDIFUN-AI With the help of AI approaches the overall diversity of the entire plankton community of the Fram Strait (Arctic) is assessed. This data is then applied to forecast future scenarios of Arctic planktonic

deep-sea focus has been on the Arctic. In 1999, the institute established a long-term observatory in Fram Strait between Greenland and Svalbard. Today, the HAUSGARTEN observatory consists of 21 monitoring [...] temperatures are provoking rapid responses in the deep-sea ecosystem. This can already be seen in Fram Strait between Svalbard and Greenland, where the composition of the phytoplankton has changed. Whereas [...] As such, it’s quite possible that climate change will reduce diversity in the biotic communities of Fram Strait. To FAQ element How will it affect the Arctic deep sea when the sea ice continues to melt?

To quantify the variation of volume, heat and salt fluxes through Fram Strait, an array of moorings is [...] salinity in the WSC in Fram Strait were highest in the 10-year observation record. An increase of the AW spatial coverage was also observed.
