Snow compaction and permafrost monitoring
chercheur principal:
Année(s) de permis: 2023 2022 2021 2020
Résumé: This licence has been issued for the scientific research application No.5475. The primary objective of this research is to determine the influence of snow manipulation on permafrost temperatures in different environments along the Inuvik to Tuktoyaktuk Highway (ITH). A secondary objective is to better understand the relationship between snow cover and ground surface temperatures in both natural...


Instrumentation and thermal monitoring of the Gunghi Creek Arch Bridge Replacement
chercheur principal:
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5466. The objectives of this research are to: 1) monitor the thermal regime of the embankment, arch, piles and road subgrade post the construction of the arch replacement; 2) use measured ground temperatures to calibrate numerical models for understanding and predicting bridge, road and embankment stability; 3) analyze mult...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal:
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 conditions along the Dempster-ITH corridor
chercheur principal:
Année(s) de permis: 2022 2021 2020
Résumé: This licence has been issued for the scientific research application No.5130. The first objective of this research is to understand how ground temperatures vary within the highway embankment between the border on the Dempster Highway and the north end of the Inuvik to Tuktoyaktuk Highway. The road surface varies little between these points and it is cleared in winter, so conditions should be un...


Permafrost in the western Arctic
chercheur principal:
Année(s) de permis: 2020 2019 2018 2017 2016
Résumé: This licence has been issued for the scientific research application No.4663. The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) to assess the physical...


Soil Carbon in the Mackenzie Delta Region
chercheur principal:
Année(s) de permis: 2015 2014 2013
Résumé: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs tundra and delta vs uplands...


Community based permafrost and active layer monitoring program
chercheur principal:
Année(s) de permis: 2013
Résumé: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal:
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:
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...


Variation of near-surface ground temperatures in spruce forests, Mackenzie Delta, Northwest Territories
chercheur principal:
Année(s) de permis: 2007 2006
Résumé: An understanding of near-surface ground temperatures will provide a baseline to assess change and identify sensitive areas. The objective of this project is to determine the variation of near-surface ground temperatures within the Mackenzie Delta. Investigations have identified four spruce forest communities in the delta based on composition: spruce-alder-bearberry, spruce-feathermoss, spruce-crow...
