Submarine glazial übertiefte Täler vor Südgrönland

Gerd Sommerhoff
Based on detailed bathymetric maps, depth profiles and 3,5-kHz-echograms the physiography and morphology of the shelf valleys off southwest- and southeast-Greenland are analysed. The submarine valleys are Ice formed troughs with an average overdeepening of 275 m. The fluvial Incision of the shelf valleys took place during a time of upllfl;ed continental margins causing a period of erosion. The postglacial marine sedimentation Is thin due to minimal terrl-genlous sediment supply and high velocities of the...
