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...
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 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...
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...
Ice surface temperature, albedo, and surface elevation change of glaciers and ice caps of the Queen Elizabeth Islands, Nunavut, Canada, 1995-2015.Download
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...
