Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: 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
Principal Investigator: Kanigan, Julian
Licensed Year(s): 2007 2006
Summary: 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...


Environmental Studies Across the Treeline, Mackenzie Delta Region
Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: The Mackenzie Delta region is characterized by diverse terrain and ecological conditions. Responsible and effective management of oil and gas exploration and potential production and pipeline construction in this region necessitates a broad but detailed understanding of environmental conditions in this region and the potential response of this environment to climate change or anthropogenic disturb...


Spatial variability of active-layer thickness and surface characteristics
Principal Investigator: Nguyen, Thai-Nguyen
Licensed Year(s): 2006 2005
Summary: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness. Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the res...


Snow Accumulation/Runoff in High Latitude Permafrost Basins
Principal Investigator: Marsh, Philip
Licensed Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to develop improved 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 s...


Long-term forest-tundra disturbance research
Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...


Holocene paleoecology of the central Canadian Arctic Islands
Principal Investigator: Gajewski, Konrad
Licensed Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: This ongoing project examines how vegetation has changed in response to changes in climate. I am using the history of vegetation, as recorded by the fossilized pollen that is present in lake sediments, to determine how vegetation in the arctic has changed over thousands of years. Fossilized pollen is collected by taking core samples from lake bottoms on Prince of Wales and Bathurst Islands. Pre...


Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...


An Evaluation of Satellite Data to Detect and Monitor Vegetation Responses to Climate Warming at Treeline
Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1993 1992 1991 1990
Summary: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...
