Glacial Erosion by the Laurentide Ice Sheet and Its Relationship to Ice, Topographic and Bedrock Conditions.

Abstract

The aim of this project was to map and analyse landscapes of glacial erosion associated with the Laurentide ice sheet and to relate them to the main variables affecting glacial erosion: basal thermal regime of the ice sheet, the topography and geology of the bed. A reconstruction of the basal thermal regime of the Laurentide ice sheet was carried out using and adapting a model developed for existing ice sheets. Using Landsat imagery, maps of landscapes of glacial erosion were compiled for the whole of the Laurentide ice sheet area with more detailed maps for the eastern Canadian Arctic. A conceptual model is developed. (Author)
