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...

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...

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...

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, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Soil Climates of the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1994
Résumé: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...
