 Abstract: We present a regional ocean model for an Antarctic circumpolar quarter-degree domain. The model uses ROMS (Regional Ocean Modeling System), with ocean-ice shelf thermodynamics parametrisation and BEC (Biogeochemical Elemental Cycling model) biogeochemistry for the ocean and CICE6.1.3 (Community Ice CodE) for the sea-ice. The models are coupled with MCT (The Model Coupling Toolkit). We show analysis of hindcast runs with ERA5 (ECMWF Reanalysis v5) and ERA-Interim (ECMWF Re-Analysis ERA-Interim) atmospheric forcing to assess the performance of the model. The model reproduces a rather realistic looking sea ice and hydrography. The model is used as part of the EU-funded Polar Regions in Earth System (PolarRES) project to get better understanding on sea-ice and ocean processes under present and future conditions.
