This report describes a numerical model designed to study the seasonal dynamics of ice-ocean interactions in the Greenland Sea. First the thermodynamic aspect of the problem is examined by means of a coupled thermodynamic sea ice-ocean mixed layer model. Secondly, the ocean dynamics is introduced by embedding the vertical zonal oceanic slab across the Greenland Sea. Sea ice and the under-lying ocean are dynamically interactive in this complete version of the coupled model. Results obtained in these two parts of the study are then outlined and, where possible, compared with some climatological data sets. A special attention is paid to the mixed layer deepening/retreat process, in relation with the seasonal evolution of the ice distribution, as an indicator of the deep convection efficiency in a region where winter deep water formation is expected to occur.
