Principal Investigator: Bell, Trevor
Licensed Year(s): 1993 1990 1988
Summary: This study will provide a better understanding of permafrost conditions in the high arctic as well as the environmental conditions that lead to permafrost formation. Study sites include the Fosheim Peninsula on Ellesmere Island and May Point and Mokka Fiord on eastern Axel Heiberg Island....

Summary: Field work for this ongoing project involves taking measure- ments of snow accumulation (from the previous winter) and meltwater accumulation (from the spring) for the White and Baby Glaciers. Changes in the size of the glaciers can provide information about whether the climate is warming. Colour Lake is being investigated because its water is acidic: data will be collected to determine the rea...

Summary: Ice caps have been used to measure changes in the chemistry of the atmosphere over long periods of time. The studies have addressed climate change, levels of pollutants resulting from human activities, and levels of materials put into the atmosphere by natural processes (e.g., volcano eruptions). This on-going study has been examining the levels of contaminants in ice caps since 1986 by collecti...

Principal Investigator: Moisan, Yves
Licensed Year(s): 1993
Summary: The field research will involve the measurement of a high arctic valley glacier using mainly portable electronic equipment in order to better understand the interaction between radar signals and a glacier surface. This exercise may contribute to more accurate interpretation of satellite radar data on glaciological phenomena....

Principal Investigator: Smith, Rod
Licensed Year(s): 1993 1992
Summary: This study concerns the overall evolution of the Lake Hazen Basin during the last glacial and deglacial cycle. It will emphasize the eastern end of the Lake Hazen Basin where prominent moraine systems exist along with former lacustrine deltas, exposed lake sediments and small lakes suitable for coring....

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...

Principal Investigator: Davis, P. Thompson
Licensed Year(s): 1992 1991 1990
Summary: The Researchers will continue to map and survey glacial abrasion limits, collect, describe and analyze soil samples from the Pangnirtung Pass and Pangnirtung Fiord areas to determine the direction and vertical extent of ice flow....

Principal Investigator: Jacobs, John D.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: The Researchers will set up an automatic climate station on Penny Ice Cap. They will service the climate station erected on Barnes Ice Cap in 1990. Amadjuak Lake and the NW margin of the Barnes ice cap will also be visited to service automatic stations installed there in previous years....

Principal Investigator: Hicock, Stephen R.
Licensed Year(s): 1992
Summary: The research will involve the study of the interplay (past and present) between glaciers, permafrost, meltwater and seawater on the southwestern side of the Bylot Island ice cap....

Principal Investigator: Weber, J.R.
Licensed Year(s): 1993 1992
Summary: In 1962 a long-term project to monitor the elevation change of the Penny Ice Cap, Baffin Island was initiated. The growth or shrinkage of an ice cap is an indicator of climate change. Change in elevation is measured by the change of the force of gravity at a particular point on the top of the ice cap. As the ice cap grows the force of gravity decreases because gravity decreases with altitude. Grav...
