Date presented: November 2017.” Includes bibliographical references. "The depiction of ground ice at the national scale necessarily includes extrapolation based on limited field data and the application of expert knowledge. Our objective is to present a methodology and early results from a new national-scale modelling effort to depict three common ground ice types: segregated ice, buried (glacigenic) ice, and wedge ice. Surfical geology, glaciation, paleo-biome, and permafrost map data combined with knowledge-based associations between environmental conditions and ground ice are used in a model within a geographic information system (GIS) to determine ground ice potentials for these three ice types”--Our approach. gccst Ice gccst Permafrost gccst Geographic data gccst Modelling Frozen ground Wolfe, Stephen Andrew, 1963- Canada.
