| Summary | This study aims to improve the understanding and quantitative characterization of permafrost- and active-layer materials in tundra environments near Lac de Gras and contribute to better understanding permafrost environments in the intermediate zone between the margins and the Keewatin Dome of the Laurentide Ice Sheet in the Slave Geological Province more broadly. The objectives are to (i) quantify the amounts and vertical patterns of excess ice, organic carbon and total soluble cations; (ii) explore factors contributing to the variation in physical and chemical characteristics between terrain types; and (iii) compare excess-ice content, organic-carbon density and total soluble cation concentration with other permafrost environments or with compilations such as overview mapsanddatabases. |
| Local Relevance | This study can inform permafrost investigations in other parts of the Slave Geological Province, and its data can support scenario simulations of future trajectories of permafrost thaw. |
