Objective(s): This study will attempt to understand and predict how cold the ground surface gets in the winter under snow cover. Temperature data, snow cover data (depth, density) and properties of the ground surface materials (density, water content and thermal properties) will be examined to determine the effect of these parameters, as affected by global warming, on permafrost and its potential degradation.
Project Description: This study will attempt to understand and predict how cold the ground surface gets in the winter under snow. Transportation to the site will be by helicopter and accommodation at the site will be in tents or at an existing cabin. Travel from camps to sample sites will be by foot. Electronic data recorders were installed in August 2000 to record air, ground and surface temperature through the winter. Difference in snowcover will be measured in April. Physical and thermal properties of the ground at each site will be measured. Soil samples of less than 1 kg will be extracted by hand from each site. This study is part of a larger project to predict permafrost temperature with climate information, so that the effects of global warming on permafrost can be predicted.
