Abstract(Summary)
This Open File publication presents mass balance (summer, winter and annual mass balance), Equilibrium Limit Altitude and Accumulation Area Ratio data for the Athabasca and Saskatchewan Glaciers (Columbia Icefield, Jasper and Banff National Parks) for 2014-15 and 2015-16. The collection of glacier mass balance data on the Athabasca and Saskatchewan Glaciers is a joint effort between Jasper National Park and Natural Resources Canada/Geological Survey of Canada. Both glaciers experienced mass losses in both of the reported years with values in 2014-15 being more negative than in 2015-16. This result reflects the inter-annual variability observed for other glaciers in southwestern Canada and the northwest Pacific. Corresponding equilibrium line elevations were higher and accumulation area ratios were lower in 2014-15 as compared to 2015-16. When placed in context with geodetic estimates of mass change for the two glaciers since the mid-1960s, the 2014-15 and 2015-16 observations generally reflect large-scale regional glacier mass balance variability observed since the mid-twentieth century.
