Influence of Permafrost Continuity on Groundwater Flow and Carbon Fate and Transport
chercheur principal: Rudolph, David
Année(s) de permis: 2023
Résumé: 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...


Characterization of recent permafrost landslides and ground ice distribution in the central Mackenzie Valley, NWT
chercheur principal: Froese, Duane G
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5423. 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...


NASA Arctic-Boreal Vulnerability Experiment (ABoVE) Airborne Initiative 2022
chercheur principal: Miller, Charles E
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5304. The extended ABoVE Study Area includes most of northwestern North America west of Hudson Bay and north and east of the coastal mountain ranges. It encompasses the variability in the key types of ecosystems that are both unique to arctic and boreal regions in North America as well as being representative of the larger ...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
chercheur principal: Mamet, Steve D
Année(s) de permis: 2023 2022 2021 2020 2019
Résumé: This licence has been issued for the scientific research application No.5282. Objectives of this research project are to determine: 1) the status of permafrost landforms; 2) long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; and, 3) the status of treeline. The research team will be examining the permafrost by thaw depth probing, and automat...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal: Smith, Sharon S
Année(s) de permis: 2023 2022 2021 2020 2019
Résumé: 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 ...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal: Smith, Sharon S
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: 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...


Active Layer Monitoring Network in the Mackenzie Valley
chercheur principal: Nixon, Mark
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: This season, a party of two will survey tubes between Tsiigehtchic and the coast during March and April and from Fort Simpson to the Arctic Coast in July and August. Staff of the Inuvik Research Centre may take late season measurements north and south of Inuvik as part of a cooperative program. Travel will be by road, small boat on the river and helicopter from Inuvik. Access to the sites is alw...


Periglacial Processes: Investigation of Slope Processes
chercheur principal: Egginton, Paul A.
Année(s) de permis: 1992 1990
Résumé: This year's work continues the measurement of creep (movement) of ice-rich slopes in permafrost. Landslide distribution in the lower Mackenzie Delta (Norman Wells area) is also being mapped....


Reconstruction of Holocene Environments
chercheur principal: Begin, Christian
Année(s) de permis: 1990
Résumé: The research team will investigate a few localities to determine the best sites to study eolian deposits (sand dunes) and features related to permafrost degradation. Samples of granular and organic deposits will be taken....
