Characterization of permafrost cores from the Inuvik-Tuktoyaktuk Corridor, NWT, Canada
chercheur principal: Alvarez, Alejandro
Année(s) de permis: 2021 2020
Résumé: This licence has been issued for the scientific research application No.4980. The objectives of this study are to: 1) evaluate the geologic setting including geochemistry, and radiocarbon ages to establish a regional history of the area; 2) investigate the geologic setting of multiple buried ice bodies; and 3) develop a geologic map along the southern Inuvik to Tuktoyaktuk Highway (ITH) highlig...

Massive Ice Study in Granular Deposits
chercheur principal: Pollard, Wayne H
Année(s) de permis: 2006 2005 2004 2003
Résumé: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...

Landscapes of the Mackenzie River delta and of the Tuktoyaktuk peninsula as possible analogues for the study of Martian landform development
chercheur principal: Soare, Richard J
Année(s) de permis: 2009 2007 2006 2005 2004
Résumé: The research objective is to sample the active layer of the permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers to understand possible cold-climate processes in the northern hemisphere of Mars. The researchers will be based in Inuvik and Tuktoyaktuk. They intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where patterned...

Vegetation Mapping at Tuktuk Nogait National Park
chercheur principal: Raillard, Martin
Année(s) de permis: 1998
Résumé: This project will take place in Tuktuk Nogait National Park in 1998 and 1999. The objective of the project is to map the vegetation of the park. As many areas of the Park as possible will be hiked and the various vegetation communities along the hiking route will be put into one of several classes, and their exact geographical location recorded. Once the field season is over, these various geograp...

Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...

Distribution and Genesis of Karst Landforms in the Northern Mackenzie Mountains, N.W.T.
chercheur principal: Hamilton, James P.
Année(s) de permis: 1991
Résumé: Karst landscapes are landforms developed on carbonate rocks in humid and temperate climates and are relatively rare in permafrost areas. The Researcher and team will focus on understanding how Karst has and is developing in the Northern Mackenzie Mountains. This will be done by identifying karst forms and examining how water moves in these environments....
