Cretacous and Younger Fossil Fauna from the area along the Peel River, N.W.T., Canada
chercheur principal:
Année(s) de permis: 1995 1990
Résumé: The researchers will collect specimens of fossil molluscs exposed in critical areas. This involves simply breaking rocks loose from their location. No excavation deeper than 1 foot is contemplated. Localities will be marked on topographic maps and measurements of sections exposed in river banks will be made. Analysis will be completed in California. Significant specimens will be returned to t...


Soil Climates of the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1994
Résumé: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...


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....


Structural and stratigraphic analysis of the northern Yukon and Beaufort-Mackenzie region
chercheur principal:
Année(s) de permis: 1993 1991 1987
Résumé: The field component of this project consists of examination of exposures of bedrock during ground surveys (on foot) at selected sites. This work will produce a geological map showing rock types, ages and positions as well as the degree to which the layers of rock have been folded or faulted during times in which mountains were formed. Licence issued for purposes of using the Inuvik Research Cent...


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...


Permafrost Studies: Western Arctic Coast
chercheur principal:
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991 1989
Résumé: This on-going research of permafrost growth involves investigations at a large lake artificially drained in 1978. The study of pingos, started in 1969, and the study of ice wedges, started in 1966, involve measurements of ice growth....


Spectral Properties of Tundra Surfaces
chercheur principal:
Année(s) de permis: 1993 1992 1991 1990
Résumé: The researcher will complete the intensive sampling of the Arctic Coastal Plain west of Shallow Bay on the Mackenzie River Delta to the Alaska border, where tundra surfaces could differ from those east of the Mackenzie Delta, high arctic tundra on northern Cape Bathurst, and additional treeline sites between Inuvik and the Horton River....


Quaternary Geology of the Beaufort Sea Coastal Plain
chercheur principal:
Année(s) de permis: 1992 1991 1990
Résumé: The researcher and his team will complete a detailed paleomagnetic sampling of the glacial and nonglacial sediments in the Morgan Bluffs of eastern Banks Island, and collect samples of boulders for Chlorine 36 dating. The data will allow the team to confirm or disconfirm previously proposed correlations and establish on a firmer basis the chronological framework for one of the longest sequences o...


Enivronmental Studies of the Ice-Bearing Region in Canadian Arctic
chercheur principal:
Année(s) de permis: 1990
Résumé: The Researcher and field team will conduct a geological survey and topographic traverse survey around the massive ground ice. They will take samples for ecological study and geochemical analysis....


Reconstruction of Holocene Environments
chercheur principal:
Année(s) de permis: 1990
Résumé: The research team will investigate a few localities to determine the best sites to study eolian deposits (sand dunes) and features related to permafrost degradation. Samples of granular and organic deposits will be taken....
