Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5270. The objective of this research is to determine the accuracy of existing physical models of the InSAR (Interferometric Synthetic Aperture Radar) dry snow signal; and, if the snow signature can be removed to enable accurate measurement of heave from winter refreezing in the active layer. There are currently three res...

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 ...

Principal Investigator: Charette, Matthew
Licensed Year(s): 2016
Summary: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...

Summary: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...

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 goal of this research is to understand how the active layer, which overlies the permafrost and thaws and re-freezes every year, will respond to environmental change, including climate warming. Active layer thickness can influence hunting, fishing, gathering and forestry through vegetation and soil conditions. The character of the active layer affects transportation and construction, while chan...

Licensed Year(s): 2009 2007 2006 2005 2004
Summary: This project’s objective is to take multiple, small .25kg samples of the active layer of permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers in their efforts to understand possible cold climate processes in the northern hemisphere of Mars. The researchers intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where polygonal...

Principal Investigator: Couture, Rejean
Licensed Year(s): 2006 2005
Summary: The main objectives of the field reconnaissance at landslide sites are as follows: o To visit landslide sites that exhibit on-going movement in order to qualify the rate of movement; o To identify main failure mechanisms and factors that contributed to slope failures; o To validate previous data collected through airphoto interpretation and remote sensing techniques; o To collect soil samples ...

Principal Investigator: Povey, Andrew
Licensed Year(s): 2005 2004 2003 2002
Summary: The 2005 terrestrial studies include vegetation mapping, rare plant surveys, rare plant mitigation planning, timber cruising, and landform, soil and permafrost investigations. All of the studies will be conducted by three- or four-person crews supported by helicopter. A local assistant will be included as part of each terrestrial survey team to assist in observing and recording data taken at surve...
