ANTARCTIC ICE SHEET SLOPE AND ASPECT BASED ON ICESAT’S REPEAT ORBIT MEASUREMENT [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Accurate information of ice sheet surface slope is essential for estimating elevation change by satellite altimetry measurement. A study is carried out to recover surface slope of Antarctic ice sheet from Ice, Cloud and land Elevation Satellite (ICESat)

Monitoring changes of the Antarctic Ice sheet by GRACE, ICESat and GNSS
Contributions to Geophysics and Geodesy, 2019 In this study, we estimate the ice mass changes, the ice elevation changes and the vertical displacements in Antarctica based on analysis of multi-geodetic datasets that involve the satellite gravimetry (GRACE), the satellite altimetry (ICESat) and the ...

The Dynamics of the Antarctic Ice Sheet [PDF]
Annals of Glaciology, 1989 A three-dimensional dynamic, thermodynamic ice-sheet model has been developed to simulate the past, present, and future behaviour of the Antarctic ice sheet. The present ice velocities depend on the deep ice temperatures which in turn depend on the past changes of the ice sheet, including surface temperature, accumulation rate, and ice thickness.

Modelling the evolution of the Antarctic ice sheet since the last interglacial [PDF]
The Cryosphere, 2014 We present the effects of changing two sliding parameters, a deformational velocity parameter and two bedrock deflection parameters on the evolution of the Antarctic ice sheet over the period from the last interglacial until the present.

Remote Sensing, 2023 In polar regions, positive feedback of snow and ice albedo can intensify global warming. While recent significant decreases in Arctic surface ice albedo have drawn considerable attention, Antarctic surface albedo variability remains underexplored.

Remote Sensing of Antarctic Glacier and Ice-Shelf Front Dynamics—A Review
Remote Sensing, 2018 The contribution of Antarctica’s ice sheet to global sea-level rise depends on the very dynamic behavior of glaciers and ice shelves. One important parameter of ice-sheet dynamics is the location of glacier and ice-shelf fronts.

Did the West Antarctic Ice Sheet Create the East Antarctic Ice Sheet? [PDF]
Annals of Glaciology, 1982 The mostly terrestrial East Antarctic ice sheet is ten times larger and probably more stable than the mostly marine West Antarctic ice sheet. It is natural to suppose that the former appeared first, and that perhaps the latter was partially formed from an outflow of East Antarctic ice onto the West Antarctic continental shelf.

Physical processes and feedbacks obscuring the future of the Antarctic Ice Sheet
Geosystems and Geoenvironment, 2022 The Antarctic Ice Sheet holds a vital role in Earth's climate system and its changes have global implications for the climate, sea level, coastal ecosystems and population.

Modeling the Antarctic ice sheet [PDF]
Annals of Glaciology, 1997 A three-dimensional (3-D), high-resolution, non-linearly viscous, non-isothermal ice-sheet model is employed to calculate the “present-day” equilibrium regime of the Antarctic ice sheet and its evolution during the last glacial cycle.

Frontiers in Earth Science, 2022 Observations of rapid ongoing grounding line retreat, ice shelf thinning and accelerated ice flow from the West Antarctic Ice Sheet (WAIS) may forebode a possible collapse if global temperatures continue to increase. Understanding and reconstructing West
