Objective(s): to determine glacial flow patterns by study of striae and groove orientations, as well as erratic and till provenance; to collect shells on raised beaches for radiocarbon and amino acid dating of sea level changes and of non-glacial intervals; to core lake bottom sediments on Charles and Wales Island in order to document late quaternary environmental change.
Project Description: In previous years research, we have been able to prove the existence of an early opening of the Hudson Strait at the end of the last Ice Age, and to establish 4 important source areas for ice flows into Hudson Strait and Ungava Bay. Our 1992 work will permit us to expand and complete the work on several offshore islands, as well as sample from an exposure of old marine sediments in the Deception River Valley in northern Ungava.
