Multi-decadal elevation changes on Bagley Ice Valley and Malaspina Glacier, Alaska
[1] Digital elevation models (DEMs) of Bagley Ice Valley and Malaspina Glacier produced by (i) Intermap Technologies, Inc. (ITI) from airborne interferometric synthetic aperture radar (InSAR) data acquired 4–13 September 2000, (ii) the German Aerospace Center (DRL) from spaceborne InSAR data acquired by the Shuttle Radar Topography Mission (SRTM) 11–22 February 2000, and (iii) the US Geological...
متن کاملIce elevations and surface change on the Malaspina Glacier, Alaska
[1] Here we use Ice, Cloud and land Elevation Satellite (ICESat)-derived elevations and surface characteristics to investigate the Malaspina Glacier of southern Alaska. Although there is significant elevation variability between ICESat tracks on this glacier, we were able to discern general patterns in surface elevation change by using a regional digital elevation model (DEM) as a reference sur...
متن کاملGlacier-specific elevation changes in parts of western Alaska
The meltwater from glaciers in Alaska contributes strongly to global sea-level rise, but accurate determination is challenging as only two comparatively small glaciers have long-term measurements of annual mass balance (Gulkana and Wolverine). Simple upscaling of their values to the entire region is error-prone as their representativeness is unknown and might be biased. Alternatively, differenc...
متن کاملAirborne and spaceborne DEM - and laser altimetry - derived surface elevation and volume changes of the Bering Glacier system , Alaska , USA , and Yukon , Canada , 1972 – 2006
Using airborne and spaceborne high-resolution digital elevation models and laser altimetry, we present estimates of interannual and multi-decadal surface elevation changes on the Bering Glacier system, Alaska, USA, and Yukon, Canada, from 1972 to 2006. We find: (1) the rate of lowering during 1972–95 was 0.9 0.1ma; (2) this rate accelerated to 3.0 0.7ma during 1995–2000; and (3) during 2000–03 ...
متن کاملSeasonal and Interannual Variability of Columbia Glacier, Alaska (2011-2016): Ice Velocity, Mass Flux, Surface Elevation and Front Position
Alaskan glaciers are among the largest contributors to sea-level rise outside the polar ice sheets. The contributions include dynamic discharge from marine-terminating glaciers which depends on the seasonally variable ice velocity. Columbia Glacier is a large marine-terminating glacier located in Southcentral Alaska that has been exhibiting pronounced retreat since the early 1980s. Since 2010, ...
