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...

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...

Summary: This ongoing survey examines permafrost so as to better understand how the active layer varies locally and regionally and how it will respond to environmental change, including but not restricted to climate change. The research team will survey from For...

Summary: The focus of this study is on the interactions between soils, climate and vegetation, and the way that these interactions control the patterns of bare soil and vegetation that are found in the Arctic. Often these patterns form circular features known as...

Summary: This project investigates the the distribution and amount of near-surface ice in sediments of the Mackenzie delta area near Inuvik. Sites near Inuvik will be accessed via road and sampled using a hand held power auger. Soil cores will be removed and taken to the Inuvik Research Center for subsequent examination. The thickness of permafrost will be measured by near-surface water jet drilling which ...

Licensed Year(s): 2000
Summary: This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...

Summary: The aim of the study of mass movements in the Richardson Mountains is to understand the processes of erosion related to climate changes. The site to be studied is located south of Little Fish Creek. The landscape looks like bench forms which are named Cryoplanation terrasses. This site was visited last year for 2-3 hours. Their formation are not really understood but we suspect that the melting of...

Licensed Year(s): 1991
Summary: 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....
