the MALIK ARCTICA beside the Brunt Ice Shelf in early January! This was the first relief of Halley Research Station by sea in several years. The teams worked incredibly hard over 9 days complete the unloading supplies, and load 6 years of waste.

The Arctic Ocean is becoming more accessible as the sea ice retreats. Expectations of increased human activity in the central ocean basins create the need for an updated approach to governance based on an improved understanding of the ecosystem and its response to the changing environment.
Deployment of the Norwegian Polar Institute’s deepest (4200 m) and northernmost (86° 32’ N) mooring “Amundsen-1” from the research vessel Kronprins Haakon though a small lead in the sea ice on 7 August 2022. Senior engineer Kristen Fossan (Norwegian Polar Institute) is releasing one of two acoustic Doppler current profilers that will provide year-round current measurements in the upper 500 m. The whole operation took around three hours to complete and required good coordination with the captain controlling the ship and crew operating a crane and a mooring winch. Recovery is planned for summer 2024.

The Norwegian Polar Institute’s sustained observatories in Fram Strait (1990-present) and northeast of Svalbard (A-TWAIN, 2010-present) are also shown.
