We have used airborne laser altimetry to estimate volume changes of 67 glaciers in Alaska from the mid-1950s to the mid-1990s. The average rate of thickness change of these glaciers was –0.52 m/year. Extrapolation to all glaciers in Alaska yields an estimated total annual volume change of –52 ± 15 km3/year (water equivalent), equivalent to a rise in sea level (SLE) of 0.14 ± 0.04 mm/year. Repeat measurements of 28 glaciers from the mid-1990s to 2000–2001 suggest an increased average rate of… Expand
Contribution of Alaskan glaciers to sea-level rise derived from satellite imagery
Over the last 50 years, retreating glaciers and ice caps (GIC) contributed 0.5 mm/yr to sea level rises (SLR), and one third is believed to originate from ice masses bordering the Gulf of Alaska.Expand
Volume changes of Alaska glaciers: Contributions to rising sea level and links to changing climate
We have used airborne altimetry to measure surface elevations along the central flowline of 86 glaciers in Alaska, Yukon Territory and northwestern British Columbia (northwestern North America).Expand
Changes of Glaciers and Climate in Northwestern North America during the Late Twentieth Century
Abstract About 75% of 46 glaciers measured using repeat airborne altimetry in Alaska and northwestern Canada have been losing mass at an increasing rate from the mid-1990s to the middle of the firstExpand
Volume change of McCall Glacier, Arctic Alaska, USA, 1956–2003
Abstract A long history of research documents that McCall Glacier, Arctic Alaska, USA, continues to lose mass at a rate that is likely increasing with time. We present a photo comparison (1958-2003)Expand
Updated estimates of glacier volume changes in the western Chugach Mountains, Alaska, and a comparison of regional extrapolation methods
and 2001/2004. Average net balance rates ranged between � 3.1 to 0.16 m yr � 1 for the tidewater and � 1.5 to � 0.02 m yr � 1 for the nontidewater glaciers. We tested several methods forExpand
Accelerating Thinning of Kenai Peninsula Glaciers, Alaska
[1] Temperate mountain glaciers are thinning at high rates and significantly contributing to sea level rise. Due to these glaciers' remote locations, remote sensing and digital elevation modelsExpand
Svalbard glacier elevation changes and contribution to sea level rise
[1] We compare satellite altimetry from the Ice, Cloud, and Land Elevation Satellite (ICESat, 2003–2007) to older topographic maps and digital elevation models (1965–1990) to calculate long-termExpand
Variations in Alaska tidewater glacier frontal ablation, 1985-2013
Our incomplete knowledge of the proportion of mass loss due to frontal ablation (the sum of ice loss through calving and submarine melt) from tidewater glaciers outside of the Greenland and AntarcticExpand
Associations between Accelerated Glacier Mass Wastage and Increased Summer Temperature in Coastal Regions
Abstract Low-elevation glaciers in coastal regions of Alaska, the Canadian Arctic, individual ice caps around the Greenland ice sheet, and the Patagonia Ice Fields have an aggregate glacier area ofExpand
Recent volume loss of British Columbian glaciers, Canada
[1] We use the Shuttle Radar Topography Mission (SRTM) data and digital terrain models from aerial photography to quantify the change of glacier volume in British Columbia (BC), Canada for the periodExpand
