Modelling Ground Ice In Permafrost Using A Paleogeographic Approach

This is an infographic that shows how new models depict ground ice in permafrost in Canada. The models use a new approach to calculate ground ice abundance in a geographic information system.

Summary Ground ice melt caused by permafrost degradation may trigger significant ecological change, damage infrastructure, and alter biogeochemical cycles. The fundamental ground ice mapping for Canada is now >20 years old, and does not include insights gained from recent field and remote sensing based studies. New modelling incorporating paleogeography is presented here to depict the distribution of three ground ice types (relict ice, segregated ice, and wedge ice) in northern Canada. The outputs are compared to the previous ground ice mapping.
