Changes along the margin of the southern half of the 5900 km 2 Barnes Ice Cap have been assessed using 1993 Landsat TM imagery in comparison with digitized 1: 50 000 NTS maps based on 1961 photogrammetry. The average recession over the 183 km long southern perimeter was found to be at least 4 m a -1 , with no significant difference between the southeast and southwest sectors. Viewed in conjunction with the sustained retreat previously reported for the northwest margin, these results indicate… Expand
Recent Changes in Areal Extent of the Devon Ice Cap, Nunavut, Canada
Abstract Image data from the years 1959/1960 and 1999/2000 reveal a 2.4% decrease in the surface area of the Devon Ice Cap, Nunavut, over the last 40 yr. This has resulted primarily from extensiveExpand
Elevation changes of ice caps in the Canadian Arctic Archipelago
[1] Precise repeat airborne laser surveys were conducted over the major ice caps in the Canadian Arctic Archipelago in the spring of 1995 and 2000 in order to measure elevation changes in the region.Expand
Monitoring the melt season length of the Barnes Ice Cap over the 1979–2010 period using active and passive microwave remote sensing data
The Barnes Ice Cap (BIC) located on Baffin Island (Nunavut, Canada) is one of the most southern ice caps of the Canadian Arctic Archipelago. Observational data provide evidence of increased melting,Expand
Perspectives on the production of a glacier inventory from multispectral satellite data in Arctic Canada: Cumberland Peninsula, Baffin Island
Abstract The consequences of global warming on land ice masses are difficult to assess in detail, as two-dimensional glacier inventory data are still missing for many remote regions of the world. AsExpand
Sensitivity of Barnes Ice Cap, Baffin Island, Canada, to climate state and internal dynamics
Barnes Ice Cap is a remnant of the Laurentide Ice Sheet, which covered much of northern North America during the Last Glacial Maximum. Barnes reached a quasi-equilibrium state ~2000 years ago and hasExpand
A new glacier inventory on southern Baffin Island, Canada, from ASTER data: I. Applied methods, challenges and solutions
Abstract The quantitative assessment of glacier changes as well as improved modeling of climate-change impacts on glaciers requires digital vector outlines of individual glacier entities.Expand
Monitoring glacier variations on Geladandong mountain, central Tibetan Plateau, from 1969 to 2002 using remote-sensing and GIS technologies
Using Geographical Information System (GIS) and remote-sensing technologies, we describe quantitative measurements of glacier variations in the Geladandong mountain region of central Tibet. Data fromExpand
Automated mapping of persistent ice and snow cover across the western U.S. with Landsat
Abstract We implemented an automated approach for mapping persistent ice and snow cover (PISC) across the conterminous western U.S. using all available Landsat TM and ETM+ scenes acquired during theExpand
Accelerated contributions of Canada's Baffin and Bylot Island glaciers to sea level rise over the past half century
Canadian Arctic glaciers have recently contributed large volumes of meltwater to the world's oceans. To place recently observed glacier wastage into a historical perspective and to determine theExpand
Glacier changes from a new inventory, Nianchu river basin, Tibetan Plateau
Abstract The ice cover of the Nianchu river basin, southern Tibetan Plateau, was mapped for 2005, using a SPOT5 scene, and for 1990 and 2000 from Landsat TM/ETM. Digital elevation models (DEMs) wereExpand


Recent changes at the northwest margin of the Barnes Ice Cap, Baffin Island, N. W. T. , Canada
A climate change monitoring site has been established at the northwest margin of the Barnes Ice Cap, in the vicinity of the Lewis Glacier. Three years of climatic data (1989 to 1992) and fieldExpand
Temperature profiles in the Barnes Ice Cap, Baffin Island, Canada, and heat flux from the subglacial terrane
Temperature measurements were made in seven boreholes, ranging in depth from 50–276 m, in the Barnes Ice Cap. Holes B4, D4, and T0975 are approximately 1 km from the margin and an average of 8 kmExpand
Flow near the Margin of the Barnes Ice Cap, and the Development of Ice-Cored Moraines
Fabric studies suggest that an up-glacier thinning wedge of deformed superimposed ice is present beneath glacial ice at the margin of the Barnes Ice Cap. Where the glacial ice contains debris, theExpand
A three‐dimensional numerical model of ice sheets: Tests on the Barnes Ice Cap, Northwest Territories
A three-dimensional numerical model of ice flow has been developed to study the areal distribution of mass in an ice sheet of arbitrary shape that is not necessarily in a steady state. The model wasExpand
Changes in mass balance, velocity, and surface profile along a flow line on Barnes Ice Cap, 1970–1984
On a number of occasions between 1970 and 1984, measurements of mass balance, surface velocity, and surface elevation were made along a 10.2 km flow line extending from the divide to the margin onExpand
Recent Variations of Sea Ice and Air Temperature in High Latitudes
Feedbacks resulting from the retreat of sea ice and snow contribute to the polar amplification of the greenhouse warming projected by global climate models. A gridded sea-ice database, for which theExpand
Analysis of glacier facies using satellite techniques
The different snow and ice types on a glacier may be subdivided according to the glacier-facies concept. The surticial expression of some facies may be detected at the end of the balance year by theExpand
