Ice surface temperature, albedo, and surface elevation change of glaciers and ice caps of the Queen Elizabeth Islands, Nunavut, Canada, 1995-2015.
DownloadFall 2017
Inter-annual variability in glacier and ice cap surface mass balance in the Queen Elizabeth Islands (QEI), Arctic Canada, is driven primarily by variability in summer melt. Mean summer (June-August) QEI glacier surface temperatures (LSTs) and shortwave broadband black-sky surface albedo (BSA) are...

Ice-atmosphere interactions in the Canadian high Arctic: implications for the thermo-mechanical evolution of terrestrial ice masses
DownloadFall 2009
Wohlleben, Trudy Monique Heidi
Canadian High Arctic terrestrial ice masses and the polar atmosphere evolve co-dependently, and interactions between the two systems can lead to feedbacks, positive and negative. The two primary positive cryosphere-atmosphere feedbacks are: 1) The snow/ice-albedo feedback (where area changes in...

Fall 2011
Time lapse imagery, an audio recorder and geophones were used to detect iceberg calving events on the Belcher Glacier, Devon Island, in the Canadian High Arctic, in order to identify the major controls on the rate and style of calving. Eleven calving events were identified between June 4th and...

Glacier behaviour in the Karakoram region of the greater Himalaya shows strong spatial and temporal heterogeneity and, in some areas, anomalous trends compared with glaciers elsewhere in High Asia. Knowledge of the mass balance fluctuations of Karakoram glaciers, as well as of the important...

Nutrient and carbon export from a tidewater glacier to the coastal ocean in the Canadian Arctic Archipelago
DownloadSpring 2021
As glaciers melt, a range of on-, in-, and under-glacier processes modify and export freshwater and sediments to the ocean. This glacial runoff may influence biological productivity in coastal ecosystems by supplying essential nutrients and labile carbon. Previous studies of glacial meltwater...

The Canadian Arctic Islands (CAI) contain the largest concentration of terrestrial ice outside of the continental ice sheets. Mass loss from this region has recently increased sharply due to above average summer temperatures. Thus, increasing the understanding of the mechanisms responsible for...

Shifts in organic matter character and microbial community dynamics from glacier headwaters to downstream rivers in the Canadian Rocky Mountains
DownloadSpring 2023
Climate change is causing mountain glacial systems to warm rapidly, leading to increased water fluxes from these catchments and concomitant export of glacially-derived sediment and organic matter (OM). Glacial OM represents an aged, but potentially bioavailable carbon pool that is compositionally...

Spatial and temporal variations of the surface energy balance and ablation on the Belcher Glacier, Devon Island, Nunavut, Canada.
DownloadSpring 2011
In the summer of 2008 (June 2nd – September 19th) detailed measurements of meteorological conditions and glacier surface properties were conducted in the Belcher Glacier catchment (718 km2), Devon Island Ice Cap, Nunavut, Canada. These measurements were used to force and validate a distributed...

Land ice is losing mass to the world’s oceans at an accelerated rate. The world’s glaciers contain much less ice than the ice sheets but contribute equally to eustatic sea level rise and are expected to continue to do so over the coming centuries if global temperatures continue to rise. It is...

High-resolution regional climate simulations of the Karakoram, Himalaya have been performed for investigation into the atmospheric dynamics in this region, and their role in the Karakoram’s snowfall accumulation and glacial evolution. It has been seen through a combination of field measurements...
