Abstract:
The purpose of this report is to describe the spatial data distribution of terrain affected by active retrogressive thaw slumping on eastern Banks Island, Northwest Territories (NWT). Thawing of ice-rich permafrost can lead to significant terrain modification, alter terrestrial and aquatic ecosystems, and pose a threat to infrastructure. This remote mapping project contributes data on the distribution and density of thaw slumps across a study region (approximately 60 km by 96 km) on eastern Banks Island. Keywords: Retrogressive Thaw Slump, Peel Plateau, Permafrost Disturbance
