Investigation of ground ice development in sediments of the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the lake....

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...

Licence #2623
chercheur principal:
Année(s) de permis: 1980
Résumé: To document fish use of shalllow side-channel areas or river margins and 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....
