Paleoclimatic Reconstruction
High Resolution Arctic Lake Sediments

      Through a program of field and laboratory-based research, we are working to extend our understanding of arctic paleoclimate over the last few millennia. The focus of this work is on the analysis of varved sediments from lakes in the Canadian High Arctic, and the watershed processes controlling sediment availability, transport, and deposition. Our objective is to produce several high resolution (annually resolved), well calibrated records along a transect from ~83°N to ~76°N, through central and southern Ellesmere Island. This project continues our previous efforts on northern Ellesmere Island (Lake C2), central Ellesmere Island (Lake Tuborg), and Cornwallis Island (Lake Sophia).
