Summary: The research aims to characterize the physical and chemical properties of forest fire smoke and its impact on the Artic. Three aircraft (CT-133 jet, Dehavilland Sea Heron and Dehavilland Twin Otter) based out of Yellowknife, equipped with standard scientific atmospheric chemistry sampling instrumentation, will be used to sample smoke while airborne. Sampling will take place opportunistically as fi...

Summary: The objective of this work is to make physical measurements of the size, shape and distribution of earth hummocks in areas where the 1968 forest fire did not occur. We are developing a mathematical model which predicts hummock size and activity based on soil properties and environmental conditions. Because hummock activity appears to be very sensitive to environmental changes, our model, coupled ...

Summary: Plant samples will be collected in the field by the researcher after they become dormat for treatment in a lab experiment. Burning treatments will be conducted in the lab where environmental growing conditions and the plant physiological state at the time of the treatment can be better controled. This will be done in order to model the effects of fire on two types of shrubs....

Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...

Summary: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...

Principal Investigator: Olsen, Sue K.
Licensed Year(s): 1992
Summary: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....

Principal Investigator: Squires Taylor, Cindy
Licensed Year(s): 1992 1991
Summary: The Researcher will conduct a survey, approximately 30 km on either side of the Mackenzie River using satellite imagery. A classification will be undertaken of the area from the Mackenzie Delta to the Fort Simpson area, with wider zones along the east side to include proposed pipeline routes. The information can be plotted as colour maps to show the location of trap lines, forest fires or wildlife...

Principal Investigator: Pollard, Wayne H
Licensed Year(s): 1990
Summary: This project will involve a comparative study of plant types and terrain conditions between a series of sites from the 1968 burn site near Inuvik with sites that are undisturbed....
