Abstract
Summary Information on thaw susceptibility is important for predicting the behaviour of permafrost as an engineering substrate. We compare apparent conductivity surveys to ground displacement obtained from differential synthetic aperture radar and surficial geology, with the objective of improving the regional characterization of terrain stability and permafrost conditions along the western coast of Hudson Bay, Nunavut. For certain field conditions, seasonal ground displacement, conductivity, and seasonal conductivity ratio are related to surficial geology, and there is a correspondence between high displacement, low conductivity, and high conductivity ratio, inferred to be indicative of high ice content and thaw-related displacement. For other conditions, results suggest heterogeneity of permafrost conditions, thaw susceptibility and conductivity that are not easily understood in terms of surficial geology alone.
