| 520 | |a“Geological Survey of Canada Open File 8229 presents an analysis of recently documented glacier volume and longitudinal profile changes to illustrate the decadal-centenary variability of mass change for a broad sample of study glaciers in Jasper National Park including those in the Columbia Icefield region. The results generally reflect large-scale regional glacier mass balance variability observed since the mid-20th century though, notably, the study glaciers are undergoing negative annual mass changes at a rate equal to or greater than thrice that of their long-term annualized centenary value (i.e., since c. 1841). While the general pattern of glacier mass loss since the mid-20th century appears to be influenced, in part, by shifts in the regime of the Pacific North American circulation pattern, it is noted that for the study glaciers and for other glaciers in southwestern Canada, the northwest Pacific and globally, mass change values over the last several decades and into early 21st century are exhibiting higher variability including several instances of record mass gains”--Summary, p. i. |
