Land Management Problems in Hydrocarbon Development Areas with Ice-Rich Permafrost: Detection and Assessment
chercheur principal:
Année(s) de permis: 2010 2009
Résumé: This licence is being issued for the scientific research application no. 946. The objective of this research is to better understand the distribution of underground ice in hydrocarbon development areas. By identifying how much ice there is, the researcher wants to study how oil/gas activities and climate change could affect the land. Underground ice is one of the most unpredictable and problema...


Enhancement of Permafrost Monitoring Network and Collection of Baseline Terrain Information in the Mackenzie Valley Corridor - Gwich'in Settlement Area
chercheur principal:
Année(s) de permis: 2006
Résumé: Gaps exist in the Mackenzie monitoring network in the permafrost zones north of Norman Wells, the Mackenzie Delta region and shorelines and coastlines. Enhancement of the network is essential to provide baseline information for developments such as pipelines, highways and power lines, and to assess the impact of such development and/or climate change on the environment. In this project, temperatur...


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...


Snow accumulation/runoff in high latitude permafrost basins
chercheur principal:
Année(s) de permis: 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: The primary objective of this project is to improve understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and snowmobile...


Pemafrost and Sump Investigations in the Mackenzie Delta Region
chercheur principal:
Année(s) de permis: 2004 2003 2002 2001 2000 2000 1999
Résumé: This research will investigate: A) the physical and chemical characteristics of permafrost in the Mackenzie Delta region to identify areas of ice-rich permafrost or thaw sensitive terrain. Second; B) the effect of permafrost degradation on water quality...


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...


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


Implications of climate change for slope stability in the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1993
Résumé: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples...


Peat Plateau Collapse and Climate Change
chercheur principal:
Année(s) de permis: 1992
Résumé: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....


International Cryosol Tour
chercheur principal:
Année(s) de permis: 1991
Résumé: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....
