(2025) Mid Holocene Rapid Thinning and Rethickening of the East Antarctic Ice Sheet Suggested by Glacial Isostatic Adjustment, Scientific Reports., https://doi.org/10.1038/s41598-025-24176-4This dataset contains computed present-day crustal uplift rates from Glacial Isostatic Adjustment (GIA) modeling for three GNSS sites around the Lutzow-Holmbukta Coast in East Antarctica: SYOG (Syowa Station), SKRV (Skarvsnes), and RUND (Rundvagshetta).
The dataset includes predictions from five ice sheet deglaciation history models (ICE-6G, RM1, RM2, RA1, RA2) calculated across a comprehensive range of Earth model parameters: lithosphere thickness (50-120 km), upper mantle viscosity (5x10^20 - 1x10^21 Pa s), and lower mantle viscosity (1x10^21 - 1x10^23 Pa s). Details of the ice sheet deglaciation history models are described in Okuno et al. (2025, Scientific Reports, in press). Each NetCDF file contains 1,008 model configurations (3 sites x 8 lithosphere thicknesses x 6 upper mantle viscosities x 7 lower mantle viscosities) with uplift rates in mm/year.
This dataset supports research on Antarctic ice sheet history, mantle viscosity structure, and present-day crustal deformation in the region.GET DATAGET DATAhttps://ads.nipr.ac.jp/dataset/A20251017-001Access to data filesCEOS IDN DIF9.72025/10/17
