2023202220212020 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...

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...

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...

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...

2006200520042003 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...

200320022001200020001999 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...

19951994199319921991 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....

1992
19911990 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....
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....
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....
