Evaluating degraded ballast and track geometry variability along a Canadian freight railroad through ballast maintenance records and ground-penetrating radar
DownloadSpring 2018
The majority of track comprising Canadaâs large railway network is constructed on ballasted foundations. As such, the accumulation of fines within the void space between the ballast aggregate, referred to as ballast degradation, is considered to be a significant factor contributing to the...

Ice-Atmosphere Interactions on the Devon Ice Cap, Canada: the Effects of Climate Warming on Surface Energy Balance, Melting, and Firn Stratigraphy
DownloadSpring 2014
In order to better constrain the magnitude of projected sea-level rise from Canadian Arctic glaciers during the 21st century warming, it is critical to understand the environmental mechanisms that enhance surface warming and melt, and how the projected increase in surface melt will translate into...

The spatial structure and temporal development of supraglacial drainage systems, and their influence on the flow dynamics of High Arctic ice caps
DownloadFall 2013
The Canadian Arctic Archipelago (CAA) contains 1/3 of global glaciers and ice caps by area. Recent increases in mean summer air temperature have resulted in increased mass loss from these glaciers, which have become the largest regional contributor to eustatic sea level rise after the continental...

Variability in Summer Anticyclonic Activity over the Canadian Arctic Archipelago and west Greenland in the late 20th/early 21st centuries, and its impact on the firn stratigraphy of the Devon Ice Cap
DownloadFall 2013
Significant summer warming over the Canadian Arctic Archipelago (CAA) is linked to a doubling in the frequency of anticyclonic circulation over the region since 2007. The frequency of positive anomalies in summer 500 hPa geopotential height is related to Arctic sea ice volume/thickness in April,...

Tidewater outlet glaciers drain approximately 47% of the ~105,000 km^2 covered by ice caps in the Queen Elizabeth Islands of Nunavut, Canada, suggesting that iceberg discharge may be an important process in the mass balance of these ice caps. Seasonal and inter-annual velocity changes of...
