The idea is to find out what’s happening underneath these glaciers, how and why they move when they do, and how climate change is affecting these dynamics. Elias icefields - the Lowell, Donjek and Kaskawulsh - using heated pressurized water and monitor them from the inside. “We normally interpret the retreat of glaciers as the glacier melting away because of climate change, but you can’t interpret surge glaciers in the same way,” said Luke Copland, who holds the University of Ottawa’s research chair in glaciology.Ĭhristine Dow, the Canada Research Chair in glacier hydrology and ice dynamics at the University of Waterloo, plans to drill into the three glaciers in the St. Eventually so much weight builds at this high point that the glacier must rebalance and the ice surges forward. This typically happens after an extended period when ice and snow build up at the highest point of the glacier. The Lowell, Dusty, and Donjek glaciers beside the Kaskawulsh are surge glaciers - meaning they periodically advance very quickly. ‘We’re on the edge of a serious crisis,’ warns editor of new report on Canada’s mountains
