How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Recent summer water shortages in Metro Vancouver are the result of unanticipated changes in the timing of regional snowmelt and rising summer temperatures. Continuing shortfalls over the next century would pose a significant challenge for water supply management decisions. To understand the magnitude of recent drought events in the context of those...
The Coast Mountains flank the Pacific Ocean in western British Columbia, Canada. Subdivided into the southern Pacific Ranges, the central Kitimat Ranges and the northern Boundary Ranges, the majority of large glaciers and icefields in the Coast Mountains are located in the Boundary and Pacific ranges. Prior descriptions of the Holocene glacial hist...
Franklin Glacier is an 18-km-long valley glacier that originates in a broad icefield below the west face of Mt. Waddington in the central British Columbia Coast Mountains, Canada. Radiocarbon-dated wood samples from the proximal faces of lateral moraines flanking Franklin Glacier show that the glacier expanded at least nine times since 13,000 cal y...
Climate change has resulted in the northward migration of many tree species in Canada and is likely to continue as greenhouse gas emissions continue to alter weather patterns. The northern range limit and expansion of trees has been frequently studied but there has been little research concerning the effects of climate change on the fluctuations th...
The recession of alpine glaciers in western Canada has proceeded unabated since the end of the Little Ice Age (LIA) in the 1860s. The following paper attempts to map the recession of one of the largest alpine glaciers in the Columbia Icefield, the Saskatchewan Glacier, located on the border of Banff and Jasper National Parks in Alberta, Canada. Usi...
The proposed research is intended as a multi-scale tree-ring study that would enable a broad spatial and temporal understanding of snow dynamics within the Pacific Ranges. The research will detail the climate response of forest stands where deep snowpacks negatively limit the growth of mountain hemlock trees and positively influence the growth of Douglas-fir trees. It is expected the research will generate information on natural SWE and snow variability on annual to millennial timescales, thereby providing the insights crucial for describing the causal factors behind the low-frequency regime shifts that lead to spatially and temporally synchronous hydroclimatic events.
