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: It is believed that during the last ice-age on northern Ellesmere Island, Lake Hazen was `pushed' further south as a result of the presence of glaciers. The researchers are investigating the Lake Hazen Basin area to determine the nature of this ancient lake. Sediment samples will be taken from both Lake Hazen as well as the surrounding area to study the past environment and organisms (now fossils...

Summary: The Cambrian period is an interval of geologic time that is poorly known in arctic Canada. Previous studies have been very basic and almost no fossils have been recovered. Sections of sedimentary rock will be measured in detail, with attention focused on the structure of the sediments as well as the presence of fossils. A map will then be constructed showing the layers in which fossils occur. ...

Summary: The Mackenzie River Valley, from Wrigley to Fort Good Hope, will be surveyed in order to document the nature of the river prior to the last glaciation. Sediments will be sampled in order to determine their age (using radiocarbon dating techniques). Field work will take place along the Mackenzie River between Wrigley and the mouth of the Redstone River, in the lower section of Gt. Bear River, and...

Principal Investigator: Harrison, J. Christopher
Licensed Year(s): 1993
Summary: The field program is intended to provide data in order to better understand the bedrock of the Canadian landmass as well as to provide basic information that can be used in land use studies, education, environmental impact analysis and resource evaluation. Data, measurements and samples will be collected on the different types of rocks found in the Vendom and Strathcona Fiord areas. The results w...

Principal Investigator: Dyke, Larry
Licensed Year(s): 1993
Summary: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples...

Summary: The aim of this ongoing research is to establish links between climate and the movements of soil. By collecting this type of data, it may be possible to determine the effect that climate changes may have on the movements of soil down slopes, into rivers and eventually into the sea....

Summary: The goal of our ongoing project is to collect samples of mud from the bottom of several undisturbed lakes on southern Baffin Island. In the laboratory, we will then examine the chemistry, texture and fossils found in this mud in an effort to document how the environment (mainly climate) of this region has changed over the past 2000 years. We hope that this work will eventually aid efforts to imp...

Principal Investigator: Lockhart, W.L.
Licensed Year(s): 1993 1992
Summary: As part of this ongoing study, sediment samples will be taken fron the deepest locations of Lac Belot and Colville Lake. These samples will be analyzed for the presence of contaminants and dated. These analyses will allow the researcher to construct histories of the input of contaminants to these lakes. In addition, lake trout, whitefish and burbot will be collected to determine what contaminan...

Licensed Year(s): 1993 1992 1991
Summary: This long-term, ongoing study is aimed at understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta. This work will allow us to better understand the natural Mackenzie Delta ecosystem, and to make better predictions of the effect of environmental change on the Delta. Cores of sediment will be collected from lake bottoms to d...
