Résumé(disponible en anglais seulement)
As part of the project "Building Resilience to Climate Change in Canadian Communities" within the Climate Change Geoscience Program of Natural Resources Canada, electrical geophysical experiments were conducted in and around the hamlet of Pangnirtung, Nunavut in August 2009. Two-dimensional electrical resistivity imaging was performed in an effort to aid permafrost characterization and landscape hazard mapping efforts in the small Inuit community on Baffin Island. The electrical geophysical data were collected in conjunction with georadar data, geomorphologic mapping and shallow borehole drilling (see LeBlanc et al., 2010). The geophysical data are more extensive, spatially continuous, and provide deeper subsurface information than the mapping and drilling data. However, the geophysical data provide proxy measurements of geology and permafrost conditions, and are thus subject to interpretation and should be considered as complementary to other forms of terrain and permafrost assessment.
