Principal Investigator:Froese, Duane G Licenced Year(s):
The objective of this research project is to search for glacial erratic boulders left behind by the retreating ice sheet margin and collect samples for cosmogenic exposure dating.
In order to obtain time constraints on the deglaciation ages in the Mackenzie River valley the research team will apply Be-10 cosmogenic exposure dating. The research team will aim to collect samples in a series of v...
Principal Investigator:Lamoureux, Scott F Licenced Year(s):
The research will require fieldwork in the Richardson Mountains between 27 April and 8 May, 2001. Research will involve the development of a high-resolution paleoenvironmental record based on lake sediments from up to six lakes in the Richardson Mountains and the Melville Hills in the NWT. Transportation in the field for the Dempster Highway study will be by snowmobile and snowshoes. If snow cov...

The aim of the Sverdrup Pass Project is to learn how vegetation returned to the artic realm after the retreat of the continental ice sheet (8000 years ago) and the prospect of the land becoming green if climate warms. The Itex project is geared to the effect of climate warming on the vegetation. The snow-fence study at Baker Lake is concerned with the effects of long-lying snow deposited on both s...
Principal Investigator:Henry, Greg H R Licenced Year(s):
Researchers have established field experiments in 5 plant communities to simulate climate change scenarios (i) no change; (ii) warmer, longer seasons with earlier snow melt; (iii) warmer growing seasons with later snow melt. The temperatures are increased in small open-topped greenhouses and the date of snow melt is changed by adding or removing snow. Tagged plants of the major vascular plant spec...
Principal Investigator:Gualtieri, Lyn Licenced Year(s):
The purpose of this research is to determine the amount of ice coverage during the last glaciation by investigating the landforms that occur today. I will also record the change in sea-level and the rise in the land as the glaciers receded. Evidence for the movement of glaciers onto eastern Ellesmere Island from Greenland will be collected. The data collected in this field season will contribut...
Principal Investigator:Retelle, Michael J. Licenced Year(s):
This study will investigate how glaciers retreat in marine waters through the analysis of the sedimentary record in front of modern tidewater glaciers. The research will determine the critical factors such as valley morphology, water depth, climatic and glaciological conditions that have influenced the retreat of the marine margin of the Grinnell Glacier since its last advance during the Litte Ice...
Principal Investigator:Kaufman, Darrell Licenced Year(s):
Three field parties will continue investigations related to past glacial activity in the eastern arctic during the last deglaciation (12,000 - 8,000 years ago). They will also research the geologic record of environmental changes preserved in lake sediments....
Principal Investigator:Beaudet, Hector Licenced Year(s):
H. Beaudet and his team intend to continue with a three year research project initially undertaken in 1987 which focusses on the glacial history of the Lake Hazen area....
Principal Investigator:Kerr, Daniel Licenced Year(s):
To collect data for PhD thesis; to investigate the nature of the Late Quaternary stratigraphic record of marine and glaciomarine deposits exposed by rivers along the mainland coast of the NWT; to define ice-front positions during ice retreat; to describe the succession of depositional environments during deglaciation; to evaluate the extent of isostatic uplift....
