Objectif(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 changes. Both topics involve fundamental aspects of long-term terrain behaviour in the region, particularly in light of potential large-scale global warming.

Description du projet: The researchers will be collecting samples of ground ice and permafrost soil, and measuring air, ground and lake water temperatures. This information will be used to provide an understanding of how permafrost conditions in the region have changed in the last few thousand years. Also measuring ground movement to determine how the ground deforms during the year, in particular, we will be measuring the tilting of trees at regular intervals, to determine the origin of the "drunken" forest. Travel will be to the sites by helicopter, or by road near Inuvik.
