Permafrost and ground hazard mapping between Norman Wells and Wrigley along the Mackenzie Valley winter road using airborne geophysics
chercheur principal: Froese, Duane G
Année(s) de permis: 2023
Résumé: 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 ...


Characterization of permafrost cores from the Inuvik-Tuktoyaktuk Corridor, NWT, Canada
chercheur principal: Alvarez, Alejandro
Année(s) de permis: 2021 2020
Résumé: This licence has been issued for the scientific research application No.4980. The objectives of this study are to: 1) evaluate the geologic setting including geochemistry, and radiocarbon ages to establish a regional history of the area; 2) investigate the geologic setting of multiple buried ice bodies; and 3) develop a geologic map along the southern Inuvik to Tuktoyaktuk Highway (ITH) highlig...


Environmental Studies Across Tree Line
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2012 2011 2010 2009 2008 2007 2006 2005
Résumé: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...


Biogeochemistry of Lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The long term goal of this research is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a more generalized ecosystem model for floodplains and deltas of major world rivers that will facilitate assessing the effects of m...


Vegetation Mapping at Tuktuk Nogait National Park
chercheur principal: Raillard, Martin
Année(s) de permis: 1998
Résumé: This project will take place in Tuktuk Nogait National Park in 1998 and 1999. The objective of the project is to map the vegetation of the park. As many areas of the Park as possible will be hiked and the various vegetation communities along the hiking route will be put into one of several classes, and their exact geographical location recorded. Once the field season is over, these various geograp...


Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...


Permafrost Investigations, western arctic Canada
chercheur principal: Burn, C. R.
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Résumé: The researchers will be collecting samples of ground ice and permafrost soil, and measuring air, ground and lake water temperatures. This information will be used to provide an understanding of how permafrost conditions in the region have changed in the last few thousand years. Also measuring ground movement to determine how the ground deforms during the year, in particular, we will be measuring ...
