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...

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...

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...

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...
