North Slave Permafrost Study: Characterization and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 2024 2023 2022 2021 2020
Summary: 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...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5419. This project continues the on-going monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. This phase of the project is largely data collection. Objectives are to provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and active la...


Measuring surface displacement using winter SAR
Principal Investigator: Rabus, Bernhard
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...


The Hidden Image of Thawing Permafrost: Mapping Subsurface Properties and Taliks with Remote Sensing (HIT Permafrost)
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...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2017 2016 2015 2014 2013 2013
Summary: This licence has been issued for the scientific research application No.5221. The project is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemome...


Understanding the Interactions between Wildfire Disturbance, Landscape Hydrology and Post-Fire Recovery in Boreal-Taiga Ecosystems
Principal Investigator: Bourgeau-Chavez, Laura L.
Licensed Year(s): 2019
Summary: The overall goal of the research is to improve understanding of the controls and impacts of a changing climate on the vulnerability and resiliency of boreal-taiga ecosystems to wildfire. This is being addressed through field sampling and process-based ecological and hydrological modeling of the 2014-2016 wildfires of southern NWT. To conduct the proposed research, the research team will addres...

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 ...


Measuring Carbon Fluxes at Illisarvik with Eddy Covariance
Principal Investigator: Skeeter, Wesley R
Licensed Year(s): 2016
Summary: The study will measure carbon dioxide (CO2) and methane (CH4) fluxes at Illisarvik during the peak of the growing season using a combination of eddy covariance and gas chamber methods. The primary objective will be to determine the magnitude of CO2 and CH4 fluxes and determine whether sequestration offsets emission. Secondary objectives will be to observe the temporal and spatial variability of th...


Permafrost, river, and groundwater inputs of trace elements and nutrients to the Mackenzie River estuary
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. ...
