Objective(s): The work considers terrain conditions during the growth of permafrost in recently drained lakes - heave of the lake bottom, development of ice wedges, changes in ground temperature - and the response of terrain in the study region to climatic change. Both topics involve fundamental aspects of long-term terrain behavior in the region, particularly in light of potential large-scale global warming.
Project Description: Samples of ground ice and permafrost soil, will be collected, and also air, ground and lake water temperatures measured. This information will be used to understand how permafrost conditions in the area have changed in the last few thousand years. We also measure ground movement to determine how the ground deforms during the year in particular we measure the tilting of trees at regular intervals to determine the origin of the "drunken" forest. Travel to sites is by helicopter, or by road near Inuvik. In 1999 the researcher will start to measure the small amounts of electricity that are created by ground freezing. We hope to provide a technique for measuring the depth of ground freezing where other methods are inadequate.
