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...

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...

Mantle composition, age and geotherm beneath the Darby kimberlite field, west central Rae Craton
DownloadFall 2018
The Rae Craton, northern Canada, contains several diamondiferous kimberlite fields that have been a focus of episodic diamond exploration. Relatively little is known about the deep mantle lithosphere underpinning the architecturally complex crust. Previous studies in the region have focused on...

Fall 2010
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...

The Age and Origin of Lithospheric Mantle Beneath Central Victoria Island and Parry Peninsula, Northern Canada
DownloadSpring 2016
New mineral major and trace element chemistry, bulk rock major element chemistry plus bulk rock and olivine PGE-Re-Os isotope data are presented for kimberlite-borne mantle xenoliths from Central Victoria Island, Nunavut and Parry Peninsula, Northwest Territories. The data, along with new and...

The mapping and dating of surficial glacial landforms and sediments across southern Banks Island document glaciation by the northwest Laurentide Ice Sheet (LIS) during the last glacial maximum. Geomorphic landforms confirm the operation of an ice stream at least 1000 m thick in Amundsen Gulf that...

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...
