Permafrost and ground hazard mapping between Norman Wells and Wrigley along the Mackenzie Valley winter road using airborne geophysics
Principal Investigator: Froese, Duane G
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 ...


The Great Bear Lake ice thickness and water quality observations under current and future climates (2022-2025)
Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5677. This project aims to reconstruct trends in ice phenology using remotely-sensed and ground-based observations and collective memories of land-based and in-lake changes by communities living along the shoreline of Great Bear Lake (GBL) to characterize the interannual variability of ice formation in the lake and determi...


Influence of Permafrost Continuity on Groundwater Flow and Carbon Fate and Transport
Principal Investigator: Rudolph, David
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5617. Within the Central Mackenzie Valley of the Northwest Territories (NWT), discontinuity and rapid change within the regional permafrost is anticipated to be influencing landscape, hydrology, habitat and ecosystem characteristics along with presenting challenges for the stability of constructed infrastructure. Mapping t...


Vulnerability of northern drinking water sources to environmental change
Principal Investigator: Comte, Jerome
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5418. The overarching goal of this project is to assess the implications of climate change on drinking water quality and practices, and to implement a community-based monitoring program. Specifically, the research team will: 1) engage and work with local communities to co-design and undertake a drinking water quality monito...


Aquatic ecosystems in the Fort Good Hope area as indicators of environmental change
Principal Investigator: Comte, Jerome
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4823. The purpose of this work is to identify indicators of aquatic ecosystem health i.e., organisms such as bacteria, phytoplankton and invertebrates that are sensitive to environmental forces and play key role in aquatic food webs, to monitor and predict the response of aquatic ecosystems to environmental changes (e.g. pe...


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.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 ...


Climate driven permafrost degradation and its impact on slope failures
Principal Investigator: Beddoe, Ryley
Licensed Year(s): 2016 2015
Summary: The objective of this research is to better understand the impact of climate driven permafrost degradation on slope instabilities and landslides in the region. This research will involve detailed investigation of both landslides that have occurred and slopes that are assessed for being at a high risk of failure. Soil samples will be taken by digging test pits within the active layer with hand ...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
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...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licensed Year(s): 2011 2010 2009 2008 2007
Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: Permafrost landforms are shrinking in response to climate warming. The researchers want to measure the amount of change each year and to measure the temperature of the permafrost year-round. In addition they want to measure the rate of plant recovery on disturbed areas resulting from the CANOL Project (1942-45). Access during the summer is via the Yukon along the Canol Road through Macmillan ...
