dc.description.abstractA regional view of large-scale glacial processes and ice-sheet dynamics on the mid-Norwegian continental shelf during the Weichselian are presented on the basis of a regional digital bathymetric dataset. At times, ice flow was mainly channellised through ice streams located in bathymetric depressions on the shelf areas. Glacial sedimentary processes are discussed with focus on the marine-based part of the Scandinavian ice sheet during the last glaciation (the Weichselian). Ice sheets that grounded on the shelf edge are throught to have been responsible for depositing complex prograding sequences reaching a maximum thickness of 1500 m on the shelf edge during several glaciations from Late Pliocene time. During interglacials, the shelf areas were sediment starved with little or no clastic sedimentation. Situated above these prograding units, several sediments packages (mainly till of Weichselian age) show a more aggradational pattern.
