Ice-atmosphere interactions in the Canadian high Arctic: implications for the thermo-mechanical evolution of terrestrial ice massesDownload
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...
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...
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...
The spatial structure and temporal development of supraglacial drainage systems, and their influence on the flow dynamics of High Arctic ice capsDownload
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 CapDownload
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,...
Ice-Atmosphere Interactions on the Devon Ice Cap, Canada: the Effects of Climate Warming on Surface Energy Balance, Melting, and Firn StratigraphyDownload
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...
Lake and sea ice and their snow covers are major components of Earthâs cryosphere and act to strongly modify climatic and biological systems. Both ice types serve as an important habitat for micro-fauna and support macro-fauna and strongly modify the exchange of energy, gases, and momentum...
Ice masses in the Antarctic, Greenland, and Canadian Arctic cover approximately 10% of the Earth’s surface, contain approximately 70% of the Earth’s freshwater, and are the top contributors to eustatic sea level rise. In recent years, these polar glacier systems have experienced significant...
The objective of this research was to evaluate recent advances in active microwave remote sensing technologies in order to further refine the optimal radar parameters for sea ice monitoring in support of marine operations and climate research. To achieve this objective, data from recent active...
Airborne radar-sounding investigations of the firn layer and subglacial environment of Devon Ice Cap, Nunavut, CanadaDownload
Airborne radio-echo sounding (RES) is a powerful tool to derive properties of glaciers and ice caps over spatially extensive areas, and has fundamentally improved our understanding of the distribution and structure of near-surface snow and firn, the ice thickness distribution and englacial...
