Summary: This licence has been issued for the scientific research application No. 5617. Within the Central Mackenzie Valley of the Northwest Territories (NWT), discontinuity and rapid change within the regional permafrost is anticipated to be influencing landscape, hydrology, habitat and ecosystem characteristics along with presenting challenges for the stability of constructed infrastructure. Mapping t...

Summary: This licence has been issued for the scientific research application No.5181. The combined temperature and active layer monitoring network extends from Fort Simpson to the Arctic Coast. With monitoring instrumentation already in place through work under previous licenses, the main work of this phase will be data collection. While different parts of the network can be visited at different times ...

Summary: The objective of this research is to better understand the impact of climate driven permafrost degradation on slope instabilities and landslides in the region. This research will involve detailed investigation of both landslides that have occurred and slopes that are assessed for being at a high risk of failure. Soil samples will be taken by digging test pits within the active layer with hand ...

Summary: This project combines the ongoing monitoring program of the same title (Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT) and the activities previously undertaken by the project title, “Active Layer Monitoring Network in the Mackenzie Valley”. The objectives of this study are to provide baseline knowledge of permafrost and terrain condit...

Summary: With climate change it is important to examine the current condition of permafrost. The research aims to measure how much it is changing by each year, and measure the temperature of the permafrost year-round. The project also aims to measure the rate of plant recovery on the disturbed areas. Intensive investigations were carried out in 1974, 1977 to 1982, and ever since 1990, when automated microc...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Summary: The main objectives of this study are to: 1. determine the status of permafrost land forms in the study area, and 2. determine the 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. Base camp is owned by Old Squaw Lodge at Camp 222. Beyond the base camp mountain bikes and foot will be the means ...

Summary: 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...
