Long‐Term River Icing Dynamics in Discontinuous Permafrost, Subarctic Canadian Shield
Abstract Icing development in the subarctic Canadian Shield is statistically related to antecedent autumn rainfall and periodic warming intervals in winter. Here, we integrate observations of streamflow, meteorology, and river icing dynamics at the Baker Creek Research Basin, Northwest Territories....
