Postglacial Isostatic Movement in Northeastern Devon Island, Canadian Arctic Archipelago
The limit of marine submergence of the last glaciation in the Cape Sparbo region varied in elevation from 65 m at Base Camp lowland, 73 m in Sparbo-Hardy lowland, to 82 m in the Skogn area; these variations are in part due to differences in time of deglaciation. Radiocarbon dates of marine shells in...
