Description: Scetch of the glaciomarine sedimentation at the margin of an ice-covered continent during interglacials (a) and during glacials (b). (a) During interglacials, sediment is eroded by the continental ice and rafted by icebergs. Sedimentation in the proximal areas of an ice covered continent are dominated by ice rafted debris (IRD), gravitational transport down the slope, supplemented by plankton shells and the hemipelagic sedimentation from the water column. A lower albedo during summer is due to a reduced sea ice coverage which on the other hand allows a higher heat flux into the atmosphere and thus evaporation and precipitation.
