Active Layer Monitoring Network in the Mackenzie Valley
chercheur principal: Nixon, Frederick M
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...

Examining Spatial and Temporal Variation of Ground Temperatures in the Mackenzie Delta, Northwest Territories
chercheur principal: Kanigan, Julian
Année(s) de permis: 2007 2006
Résumé: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...

The Influence of Snowcover on the Ground Surface Temperature in Permafrost
chercheur principal: Riseborough, Dan
Année(s) de permis: 2001 2000
Résumé: This study will attempt to understand and predict how cold the ground surface gets in the winter under snow. Transportation to the site will be by helicopter and accommodation at the site will be in tents or at an existing cabin. Travel from camps to sample sites will be by foot. Electronic data recorders were installed in August 2000 to record air, ground and surface temperature through the wi...
