5203 |a"This Open File summarizes ground ice information from 31 sites across the permafrost regions in Canada. The poster presents a map with photographs from each site, and estimates of ground ice abundance from segregated, wedge, and relict ice in top 5 m of permafrost, derived from national-scale mapping by O'Neill et al. (2019; 2020). The sites represent a range of environmental conditions (climate, surficial geology, geological history, vegetation) spanning the continuous and discontinuous permafrost zones in Canada. The report in the Open File provides detailed site descriptions, comments on the modelled ground ice abundance compared to observations of ground ice from the area, the implications of ground ice conditions for thaw processes (thermokarst), and references to key literature. The atlas illustrates the varied ground ice conditions in northern Canada and the associated environmental conditions that control ice type and abundance. Furthermore, the atlas serves as a means to validate and improve recent national-scale ground ice mapping by identifying conditions not well represented by the modelling. This validation has highlighted that an updated national surficial geology dataset that incorporates the latest large-scale GSC mapping would improve the model outputs in many areas by more accurately depicting the distribution of frost-susceptible sediments"--Abstract, page 1.
