2. Irminger Sea – A key region for climate variability MODIS SST AUGUST 2003 • Convergence of Arctic, Atlantic, Intermediate and Dense Waters • Freshwater transport into the subpolar region • Large air/sea exchange: Intermediate Convection • Transformation of the dense overflows • Supply of warm ocean waters to Greenland’s outlet glaciers
