| Summary | The purpose of this report is to present results from the first regional-scale approach to map permafrost-related landforms in the Slave Geological Province, together with a compilation of sedimentological and cryostratigraphic records for this region that have been extracted from available reports. The objectives of this study are to: i) identify and classify various permafrost-related landforms using high-resolution satellite imagery acquired for a 10-km-wide swath of land (8576 km2 area of interest) aligned with the proposed corridors for the Slave Geological Province Corridor Project, NT, and the Grays Bay Road and Port Project, NU; ii) provide quantitative measures of the distributions and densities of the set of landforms and determine their associations with surficial geology; and iii) identify and digitally compile the data from available sedimentological and cryostratigraphic records to increase its utility and accessibility. This knowledge on thaw-sensitive permafrost conditions is needed to inform decisions regarding development of resources and climate resilient northern infrastructure, to identify potential geohazards, and to make inferences on past and future landscape evolution. |
| Local Relevance | This report presents a digital georeferenced database of landforms identified in permafrost terrain within the proposed corridors of the Slave Geological Province Corridor Project in the NWT. |
