In order to study how the dynamics of mesoscale turbulent eddies in the Arctic Ocean in the presence of sea ice affect the rate of sea ice loss, a highly accurate simulation model of sea ice and the ocean in the Arctic, SEDNA (Sea ice - EDdy resolving ocean paN-Arctic configuration), has been developed on a European supercomputer, Joliot-Curie AMD Irene ROME (ROME). The size of ROME does not allow us to perform long simulations of more than ten years. The goal of this project is to determine the feasibility of running long SEDNA simulations (over a few decades) on the supercomputer Fugaku.
