Deformation in Rutford Ice Stream, West Antarctica: measuring shear-wave anisotropy from icequakes [PDF]
, 2013 Ice streams provide major drainage pathways for the Antarctic ice sheet. The stress distribution and style of flow in such ice streams produce elastic and rheological anisotropy, which informs ice-flow modelling as to how ice masses respond to external

Elevation and elevation change of Greenland and Antarctica derived from CryoSat-2 [PDF]
The Cryosphere, 2014 This study focuses on the present-day surface elevation of the Greenland and Antarctic ice sheets. Based on 3 years of CryoSat-2 data acquisition we derived new elevation models (DEMs) as well as elevation change maps and volume change estimates for both

Genesis of the Antarctic Slope Current in West Antarctica
Geophysical Research Letters, 2020 The stability of the West Antarctic Ice Sheet (WAIS) depends on ocean heat transport toward its base and remains a source of uncertainty in sea level rise prediction.

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]
, 2005 The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Environmental Research Letters, 2023 Antarctic climate changes prior to 2000 were characterized by a strong zonally asymmetric pattern. Over 90% of the land ice mass loss occurred around a limited area in West Antarctica, accompanied by a rapid surface warming rate about three times the ...

Long-Term Variability of Surface Albedo and Its Correlation with Climatic Variables over Antarctica
Remote Sensing, 2016 The cryosphere is an essential part of the earth system for understanding climate change. Components of the cryosphere, such as ice sheets and sea ice, are generally decreasing over time.

A continuum model (PSUMEL1) of ice mélange and its role during retreat of the Antarctic Ice Sheet [PDF]
Geoscientific Model Development, 2018 Rapidly retreating thick ice fronts can generate large amounts of mélange (floating ice debris), which may affect episodes of rapid retreat of Antarctic marine ice.

Accelerated ice-sheet mass loss in Antarctica from 18-year satellite laser ranging measurements
Annals of Geophysics, 2016 Accurate estimate of the ice-sheet mass balance in Antarctic is very difficult due to complex ice sheet condition and sparse in situ measurements. In this paper, the low-degree gravity field coefficients of up to degree and order 5 derived from Satellite

West Antarctic sites for subglacial drilling to test for past ice-sheet collapse [PDF]
The Cryosphere, 2018 Mass loss from the West Antarctic Ice Sheet (WAIS) is increasing, and there is concern that an incipient large-scale deglaciation of the marine basins may already be underway. Measurements of cosmogenic nuclides in subglacial bedrock surfaces have the

Geophysical characteristics of the Terror Rift, West Antarctica
Dizhi lixue xuebao, 2021 In this paper, we investigated the Terror Rift where the last stage of Cenozoic rifting in the West Antarctic Rift System (WARS) took place. The International published and domestic sampled during CHARE seismic reflection profiles are utilized. Combining
