| Summary: | <!--!introduction!--> The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the polar front into an Atlantic-dominated domain in the south, and an Arctic-dominated domain in the north. The polar front is a thermohaline structure, which is topographically-steered at sub-surface, and influenced by the seasonal sea ice edge near the surface. Exchanges of nutrients between the inflowing Atlantic Water and the surrounding waters are key for the primary production in the Barents Sea. In October 2020, we measured nutrients, dissolved inorganic carbon (DIC), ocean stratification, currents and turbulence in the vicinity of the polar front in the Barents Sea within the framework of the Nansen Legacy project, allowing estimates of horizontal and vertical advective fluxes and turbulent fluxes of nitrate and DIC. We found a substantial transfer of nitrate and DIC across the polar front from the Atlantic ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
