Progress in Mesozoic-Cenozoic paleomagnetism and plate reconstruction of West Antarctica
Dizhi lixue xuebao, 2021 In this study, we summarized paleomagnetic data from West Antarctica and reconstructed the paleoposition of different crustal blocks of West Antarctica. Plate reconstructions identified two widely influenced tectonic events in West Antarctica due to the ...

EXTRACTION OF ICE FLOW VELOCITY BY COMBINATION OF DINSAR AND OFFSET TRACKING METHODS FOR PINE GLACIER, WEST ANTARCTICA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 West Antarctica is the main contributor to global sea level rise at present and in the coming decades, since it occupies 80% of mass loss in Antarctica.

The Antarctic Amplification Based on MODIS Land Surface Temperature and ERA5
Remote Sensing, 2023 With global warming accelerating, polar amplification is one of the hot issues in climate research. However, most studies focus on Arctic amplification, and little attention has been paid to Antarctic amplification (AnA), and there is no relevant ...

The life and death of a subglacial lake in West Antarctica
Geology, 2023 Over the past 50 years, the discovery and initial investigation of subglacial lakes in Antarctica have highlighted the paleoglaciological information that may be recorded in sediments at their beds.

Constraints on the Timing and Extent of Deglacial Grounding Line Retreat in West Antarctica
AGU Advances, 2023 Projections of Antarctica's contribution to future sea level rise are associated with significant uncertainty, in part because the observational record is too short to capture long‐term processes necessary to estimate ice mass changes over societally ...

Rapid glacier retreat rates observed in West Antarctica
Nature Geoscience, 2022 The Pope, Smith and Kohler glaciers, in the Amundsen Sea Embayment of West Antarctica, have experienced enhanced ocean-induced ice-shelf melt, glacier acceleration, ice thinning and grounding-line retreat in the past 30 years.

Simulated Twentieth‐Century Ocean Warming in the Amundsen Sea, West Antarctica
Geophysical Research Letters, 2022 Rapid ice loss is occurring in the Amundsen Sea sector of the West Antarctic Ice Sheet. This ice loss is assumed to be a long‐term response to oceanographic forcing, but ocean conditions in the Amundsen Sea are unknown prior to 1994.

Geophysical Research Letters, 2022 Ice motion and boundaries are critical information for ice sheet models that project ice evolution in a warming climate. We present four historical, continent‐wide, maps of Antarctic‐wide ice motion and boundaries for the time period 1995–2022.

An Assessment of ERA5 Reanalysis for Antarctic Near-Surface Air Temperature
Atmosphere, 2021 The European Center for Medium-Range Weather Forecasts (ECMWF) released its latest reanalysis dataset named ERA5 in 2017. To assess the performance of ERA5 in Antarctica, we compare the near-surface temperature data from ERA5 and ERA-Interim with the ...

Bedforms of Thwaites Glacier, West Antarctica: Character and Origin
Journal of Geophysical Research - Earth Surface, 2021 Bedforms of Thwaites Glacier, West Antarctica both record and affect ice flow, as shown by geophysical data and simple models. Thwaites Glacier flows across the tectonic fabric of the West Antarctic rift system with its bedrock highs and sedimentary ...
