| Summary: | <!--!introduction!--> The Southern Ocean plays a fundamental role in the global carbon cycle. Physical and biogeochemical processes, including primary production and the upwelling of carbon-rich water masses, govern carbon exchange between the atmosphere and ocean carbon reservoirs. To study this region, we configured a regional East-Antarctic simulation derived from ECCO-Darwin, a global-ocean biogeochemistry model that assimilates both physical and biogeochemical observations. Our regional ocean model extends from the Antarctic Continent to 60°S and from 100°E to 150°E with horizontal grid spacing of 3–4 km. The model domain includes the Shackleton, Conger, Totten, Moscow University, Holmes, Dibble, and Mertz ice shelves. Since the biogeochemical component of ECCO-Darwin is optimized to best fit global observations, model-data agreement for the East Antarctic region requires further adjustments. For example, (1) simulated upper-100 m nutrient fields are biased high and typical Circumpolar-Deep-Water ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
