Mass change of Arctic ice caps and glaciers: implications of regionalizing elevation changes [PDF]
The Cryosphere, 2013 Abstract. Recent studies have determined mass changes of Arctic ice caps and glaciers from satellite altimetry. Determining regional mass balance of ice caps and glaciers using this technique is inherently difficult due to their size and geometry. Furthermore these studies have mostly relied on one method or the same types of methods to determine the ...

Ice elevations and surface change on the Malaspina Glacier, Alaska [PDF]
Geophysical Research Letters, 2005 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 ...

Changes in elevation and mass of Arctic glaciers and ice caps, 2010–2017
Remote Sensing of Environment, 2021 Arctic glaciers and ice caps (GIC) are losing mass rapidly, and this process is expected to continue during the 21st century owing to polar amplification of climate warming. Here, we use seven years of CryoSat-2 swath interferometric altimetry to track changes in the volume of Arctic GIC.

Recent changes in glacial area and volume on Tuanjiefeng peak region of Qilian Mountains, China. [PDF]
PLoS ONE, 2013 Glaciers' runoff in the Qilian Mountains serves as a critical water resource in the northern sections of the Gansu province, the northeastern sections of the Qinghai province, and the northeastern fringe of the Tibetan Plateau.

Glacier-specific elevation changes in parts of western Alaska [PDF]
Annals of Glaciology, 2015 AbstractThe 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).

Terrestrial, Atmospheric and Oceanic Sciences, 2021 We detect long-term elevation changes near a glacier terminus and an icefield in Tanggula Mountains from altimeter data from the TOPEX/Poseidon (T/P), Jason-1 (J1), Jason-2 (J2), and Jason-3 (J3) altimeters. An altimeter processing technique is developed

Sustained retreat of the Pine Island Glacier [PDF]
, 2013 We use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and shoaling of the glacier surface and bedrock slopes, respectively, which ...
