Deglaciation of the NW Laurentide Ice Sheet and opening of the Mackenzie valley
Principal Investigator: Froese, Duane G
Licensed Year(s): 2019 2018
Summary: In this project, the research team aim to improve the chronology of the retreat of the Laurentide Ice Sheet from the eastern foot of the Mackenzie Mountains and the Mackenzie River valley that began around 14,000 years ago, and to gain better understanding of the dynamics of how the ice left the region and development of large lakes that occupied the valleys. The team will attempt to quantify the ...

Timing of deglaciation of the Mackenzie River valley 60-67 dg N
Principal Investigator: Froese, Duane G
Licensed Year(s): 2015
Summary: 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...

Late Quaternary History of the Richardson Mountains and the Melville Hills
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2001
Summary: 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...

1. Initial Phase of Primary Sucession Following Glacial Retreat 2. Secondary Metabolites in Arctic Willow 3. Photosynthesis and Respiration in Blue-Green Algae 4. Revegetation of Snow/ Ice Landscapes During Lt. Ice Age 5. Monitoring of ITEX
Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: 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...

Responses of Circumpolar Plant Species and Their Communities To Simulated Climate Change
Principal Investigator: Henry, Greg H R
Licensed Year(s): 1994 1993 1992
Summary: 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...

The Quaternary history of Scoresby Bay, Ellesmere Island
Principal Investigator: Gualtieri, Lyn
Licensed Year(s): 1993
Summary: 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...

Processes and Sediments in Retreating Tidewater Glaciers, Southern Baffin Island
Principal Investigator: Retelle, Michael J.
Licensed Year(s): 1992
Summary: 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...

INSTAAR Geological Fieldwork 1992, Northwest Territories, Canada
Principal Investigator: Kaufman, Darrell
Licensed Year(s): 1992
Summary: 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....

Quaternary History of Lake Hazen area, Northern Ellesmere Island
Principal Investigator: Beaudet, Hector
Licensed Year(s): 1989 1988 1987
Summary: 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....

Stratigraphy of late Quaternary coastal marine sediments, Horton to Ellice Rivers, NWT
Principal Investigator: Kerr, Daniel E.
Licensed Year(s): 1988 1987
Summary: 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....
