Summary: This licence has been issued for the scientific research application No. 5688. The objectives of this research project are to: 1) fly multiple lines of airborne electromagnetic (AEM) geophysical data (between 4 and 6 parallel lines ~100 m apart) between Inuvik and Tuktoyaktuk, beginning and ending just outside the communities; 2) using the geophysical and geological data, produce maps of the In...

Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5160. The research team will use airborne geophysics (helicopter-based surveys) flying the central Mackenzie Valley corridor along the existing winter road to map permafrost across different landforms and terrain types. The objectives of this study are to: 1) Fly multiple lines of airborne electromagnetic geophysical data ...

Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5544. This proposed research will build on the previous years’ studies completed in the Mackenzie River valley by researchers at the Permafrost Archives Laboratory at the University of Alberta. The objective of fieldwork being completed in 2023 are as follows: 1) to evaluate the integrity and containment of contaminants of ...

Licensed Year(s): 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.4905. This work builds on studies over the last several years, including field work in the Mackenzie River valley in 2018 and 2019. The objective of 2021 fieldwork is twofold: 1) characterizing a large suite of retrogressive thaw slumps and thaw-induced landslides in the Redstone, Keele, and Johnson River basins that have i...

Licensed Year(s): 2020 2019 2018
Summary: In this project, the research team aim to improve the chronology of the retreat of the Laurentide Ice Sheet from the eastern foot of the Mackenzie Mountains and the Mackenzie River valley that began around 14,000 years ago, and to gain better understanding of the dynamics of how the ice left the region and development of large lakes that occupied the valleys. The team will attempt to quantify the ...

Licensed Year(s): 2017 2016
Summary: The objective of this project is to investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating. The research team will investigate the stratigraphic description of sedimentary sections in the river banks cutting through the Pleistocene deltas. Collection of samples are for rad...

Licensed Year(s): 2015
Summary: The objective of this research project is to search for glacial erratic boulders left behind by the retreating ice sheet margin and collect samples for cosmogenic exposure dating. In order to obtain time constraints on the deglaciation ages in the Mackenzie River valley the research team will apply Be-10 cosmogenic exposure dating. The research team will aim to collect samples in a series of v...

Licensed Year(s): 2010
Summary: The objectives of this study are to observe and document sediments exposed along the upper Rat River, also to collect samples of sediments for potential radiocarbon dating. Researchers will fly into area via helicopter from Old Crow. Where possible the helicopter will land adjacent to river escarpments for access to large river bars or wide banks. Researchers will climb up banks to observe sedi...
