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: 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: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...

Summary: This research is part of an aerial reconnaissance program to study spring breakup at the major watercourse crossings along the proposed pipeline right-of-way from the Deh Cho region in the south to the Inuvialuit Settlement Region in the north. The resea...

Summary: Research will be conducted in a fen-bog complex approximately 5 km west of Fort Simpson. Gas samples will be obtained using portable chambers and later analyzed using gas chromotography. Cores will be collected using a peat corer and a modified ice auger. Peat temperatures, water levels, plant growth rates and water chemistry will also be measured. Geophysical mapping using ground penetrating ...

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...
