Description

Scetch of the glaciomarine sedimentation at the margin of an ice-covered continent during interglacials (a) and during glacials (b).

(b) During glacials, the gravitational sediment transport is dominant. A lower sea level provides suitable conditions for buldozed deposits on the shelf by the advancing ice sheet. Primary production is reduced due to missing light in surface waters under a continous closed sea ice coverage which also prevents icebergs to calve and to distribute its sediment load.
