Abstract

The morphological processes of the subpolar region of the Labrador and Irminger Sea and their influences on the sea bottom features are discussed. The generation of the original crustal features by sea floor spreading processes and the shaping of the sea bottom features by glacial and recent processes are described. During the glacial periods lowering of the sea level and shelf glaciation were responsible for an increased terrigenious sediment supply and have caused gravitational mass movement (sliding, slumping, mud flow) and turbidity currents on the continental slopes and rises. The recent morphodynamic is characterized by strong surface and bottom currents whose morphological influences during the glacial periods were reduced by the interruption of the East Greenland current and the overflow across the Denmark strait.
