Accelerated Elevation Change of Greenland's Jakobshavn Glacier Observed by ICESat and IceBridge
IEEE Geoscience and Remote Sensing Letters, 2013The recent accelerated ice mass loss of the Greenland ice sheet and its outlet glaciers has been widely documented. The Jakobshavn isbrae/glacier is one of the fastest melting glaciers in Greenland. To determine its elevation change rate, recent observations from the laser altimetry mission Ice, Cloud, and land Elevation Satellite (ICESat) (2003-2009 ...

Recent elevation and velocity changes of Astrolabe Glacier, Terre Adelie, Antarctica
2015 8th International Workshop on the Analysis of Multitemporal Remote Sensing Images (Multi-Temp), 2015SPOT and Pleiades images acquired since 2002 are used to describe velocity and elevation changes on Astrolabe Glacier, East Antarctica. Multi-temporal pairs of images are used to generate velocity fields by automatically tracking surfaces features. Stereo-pairs are used to create DEMs.

dhdt: a Python library to transform shifting shadows to glacier elevation change
2023The free and open data policy of the Landsat legacy and the Sentinel-2 satellite constellation have enhanced our knowledge considerably. This enrichment is due to an increase in spatial spread; from glacier change at targeted glaciers, to a coverage at regional or global scale.

Observing glacier elevation changes from spaceborne optical and radar sensors
2023Quantifying glacier elevation and volume changes is critical to understanding the response of glaciers to climate change and related impacts, such as regional runoff and global sea-level rise. Spaceborne remote sensing techniques enable the quantification of spatially distributed glacier elevation changes at regional and global scales using multi ...

The Glacier studies are important for monitoring the hydrological cycle as well as the impact of climate change. Recent studies indicate that the glacier area-shrinking rate is accelerating specifically in the Himalayan glaciers. In this study, an integrated approach based on semi-automatic method has been used over the Chhota-Shigri glacier.

Surface elevation changes of glaciers derived from SRTM and TanDEM-X DEM differences
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013We compare ice elevation from TanDEM-X DEMs of 2011/2012 and SRTM DEM of 2000 over the Southern Patagonia Icefield (SPI) in order to quantify the volume loss of the icefield over the last decade. The map of elevation change rate is discussed. Detailed results are shown for two glaciers: Jorge Montt and Pio XI, exhibiting opposite trends in elevation ...

Changes in surface elevation and extent of the Kaskawulsh Glacier, Yukon Territory
2013Between 1977 and 2007, the Kaskawulsh Glacier underwent an overall decrease in volume of between 2.76 km3 water equivalent (we) and 4.60 km3 we, and a decrease in area of 2.27%. Volume losses are consistent with changes observed at most glaciers in the Yukon/Alaska region which are thinning and/or retreating (Arendt et al. 2006; Chen et al.
