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...

Principal Investigator: Grünberg, Inge
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5196. The goal for this expedition is to collect ground-truth data for two prior airborne campaigns conducted in 2018 and 2019. The data obtained from radar remote sensing of the area around Trail Valley Creek represent a complex signal from the vegetation, active layer, and permafrost. Based on prior field expeditions, the...

Summary: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. This phase of the project is largely data collection. The specific objectives are: 1) to provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and ...

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. ...

Principal Investigator: Yoshikawa, Kenji KY
Licensed Year(s): 2013
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...

Principal Investigator: Gilbert, Graham L
Licensed Year(s): 2010
Summary: The objectives of this project are to define the impact of snow depth, surface vegetation, and soil characteristics on spatial and temporal variations in active-layer freeze-back in the low arctic tundra east of the Mackenzie Delta. The duration of freeze back will be determined from the ground temperatures measured at the top of permafrost. This temperature only declines at the site when the ac...

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): 2008
Summary: The objective of this project is to conduct snow surveys at selected sites in the Mackenzie Delta, related to permafrost studies. Snow surveys will be carried out at three selected sites in the Delta during early April. These are Circumpolar Active Layer Monitoring Program sites. There is a grid marked on these locations, where the researchers will be measuring the snow pack and snow density. M...
