Implications of climate change for slope stability in the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1993
Résumé: 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...

Contemporary channel characteristics and behaviour along the lower reaches of major tributaries of the Mackenzie River (from Norman Wells to the Mackenzie Delta)
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: The research will provide basic information on the characteristics of the rivers and valleys that are major tributaries emptying into the Mackenzie River. The tributaries to be studied include the Carcajou, Mountain, Hume, Ramparts, Hare Indian, Ontaratue, Arctic Red and Peel Rivers. Little is known about the lower 5-7 km portion of these rivers. The information collected will include both aeri...

The Nature and Origin of Ground Ice in the High Arctic and Icing as a Hydrologic Component of Northern Drainage Basins
chercheur principal:
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: The researchers will gain a better understanding of permafrost conditions of the study area and the environmental conditions under which permafrost formed and evolved. They will also investigate icings and icing processes, since icings are a hydrologic phenomenon and their occurance has implications for recharge and runoff of drainage systems and water resource management....

Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
chercheur principal:
Année(s) de permis: 1992
Résumé: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Trace Organic Contaminants in Arctic Snow and Aquatic Ecosystems
chercheur principal:
Année(s) de permis: 1992 1991 1991 1990
Résumé: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...

Licence #2661
chercheur principal:
Année(s) de permis: 1981
Résumé: To document fish use of shallow side channel areas or river margins to estimate the effect of water level changes on fish habitat. Detailed physical data collection (water levels, velocity and sediment samples) will be undertaken, data will also be collected of fish and small invertebrate use of habitat....
