The impact of sea ice diSappearance on highEr North aTlantic clImate and atmospheric bromiNe and mErcury cycLes (SENTINEL)

Project description:
The disappearance of sea ice in the Barents Sea, and the changing sea ice conditions in the Fram Strait impact heat exchanges between the sea surface and the atmosphere. These in turn could affect mercury deposition rates and the ozone atmospheric lifetime through changes in the amount of bromine radicals released from the first-year sea ice surface. This project aims to shed light on these phenomena by combining field and instrumental data and atmospheric and climate modelling. In the framework of the SENTINEL project, two deep ice cores down to the bedrock will be drilled on the Holtedalfonna ice cap in spring 2023.
