North Slave Permafrost Study: Characterization and Predicting Discontinuous Permafrost for Climate Change Adaptation
chercheur principal: Wolfe, Stephen A
Année(s) de permis: 2024 2023 2022 2021 2020
Résumé: This licence has been issued for the scientific research application No. 5775. This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Diffe...


Monitoring the impacts of permafrost thaw on water resources at Scotty Creek, NWT
chercheur principal: Quinton, William L.
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5781. The long-term objective of this research programme is to improve the understanding, parameterisation and prediction of water flow and storage processes in peatland-dominated, thawing, discontinuous permafrost. Over the next 5 years, significant progress toward this long term objective will be made through the foll...


Permafrost and ground hazard mapping along the Inuvik-Tuktoyaktuk Highway using airborne geophysics
chercheur principal: Froese, Duane G
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5688. The objectives of this research project are to: 1) fly multiple lines of airborne electromagnetic (AEM) geophysical data (between 4 and 6 parallel lines ~100 m apart) between Inuvik and Tuktoyaktuk, beginning and ending just outside the communities; 2) using the geophysical and geological data, produce maps of the In...


A Multi-scale Assessment of Cumulative Impacts in the Northern Mackenzie Basin
chercheur principal: Lantz, Trevor C.
Année(s) de permis: 2016 2015 2014 2013 2012
Résumé: This project has three main objectives: Objective 1: To use satellite imagery (Landsat, QuickBird, InSAR, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, etc.) in the northern Mackenzie Basin. To quantify landscape disturbances and vegetation regeneration patterns since 1985 Landsat satellite images will be obtained, that will provide refle...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Résumé: Permafrost landforms are shrinking in response to climate warming. The researchers want to measure the amount of change each year and the temperature of the permafrost year-round. In addition they want to measure the rate of plant recovery on disturbed areas resulting form the CANOL Project (1942-45). The main study objectives are to: 1. determine the status of permafrost landforms in the stud...


Pemafrost and Sump Investigations in the Mackenzie Delta Region
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2004 2003 2002 2001 2000 2000 1999
Résumé: This research will investigate: A) the physical and chemical characteristics of permafrost in the Mackenzie Delta region to identify areas of ice-rich permafrost or thaw sensitive terrain. Second; B) the effect of permafrost degradation on water quality...


Investigation of ground ice development in sediments of the Mackenzie delta area.
chercheur principal: Burn, Chris R
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: The purpose is to collect samples of ground ice and to measure air, ground, and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousands years, in order to determine what might happen in the future....


Permafrost Adjustment to Coastal and Deltaic Processes: Beaufort Sea and Mackenzie Delta
chercheur principal: Dyke, Larry
Année(s) de permis: 1992 1991 1990
Résumé: The research will involve permafrost adjustment studies on the outer Delta as well as preliminary work on landslide mechanisms along the Mackenzie River between Norman Wells and the head of the Mackenzie Delta. The purpose of the work is to understand the importance of sedimentary processes in controlling the growth and disappearance of permafrost along the coast of the Beaufort Sea....


Reconstruction of Holocene Environments
chercheur principal: Begin, Christian
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....


Licence #4055
chercheur principal: Pilon, Jean
Année(s) de permis: 1984
Résumé: To carry on with the establishment of a series of permafrost observatories in the NWT to provide a cross section of permafrost conditions, through wihch to conduct long term reserch on permafrost characteristics, permafrost stability, permafrost climate interaction and its response to man induced and natural disturbances, at which to evaluate new tools to determine the properties of permafrost....
