Includes bibliographical references. “A field campaign was conducted in 2012-2017 to collect baseline geoscience data to determine air, surface, and near-surface ground temperature conditions along the Tibbitt to Contwoyto Winter Road (TCWR), Great Slave region, Northwest Territories. This field initiative was conducted in support of Natural Resources Canada’s Climate Change Geoscience Program project entitled Transportation Risk in the Arctic to Climatic Sensitivity. Thermal data are presented in a digital format that can be utilized for assessments of permafrost sensitivity to climate change and for infrastructure planning”--Abstract, p. iii. gccst Permafrost gccst Air temperature Earth temperature Environmental geology Morse, Peter Douglass, 1975- Wolfe, Stephen Andrew, 1963- Canada.
