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.Jun'ichi OkunoNational Institute of Polar ResearchNone10-3, Midori-choTachikawaTokyo190-8518Japanokuno@nipr.ac.jpresourceProviderAkihisa HattoriNational Institute of Polar ResearchNone10-3, Midori-choTachikawaTokyo190-8518JapanNoneresourceProviderSOLID EARTH > GEOMORPHIC LANDFORMS/PROCESSES > TECTONIC PROCESSES > ISOSTATIC UPLIFTCRYOSPHERE > GLACIERS/ICE SHEETS > ICE SHEETS > SURFACE MORPHOLOGYNASA / GCMD Keywords Version 10.52008-02-05revisionJP/MEXT/NIPRNASA / GCMD Keywords Version 10.52008-02-05revisionJARENASA / GCMD Keywords Version 10.52008-02-05revisionGpsComputersNASA / GCMD Keywords Version 10.52008-02-05revisionCONTINENT > ANTARCTICANASA / GCMD Keywords Version 10.52008-02-05revisionWorld > Antarctica > Antarctica > AntarcticaISO3166-1 Country codesClimate ChangeGEOSS themes V2Glacial Isostatic AdjustmentCrustal deformation rateGNSSHolocene ice melting historymantle viscosityEast Antarctic Ice SheetFree KeywordCC BY-SA(http://creativecommons.org/licenses/by-sa/4.0/)engutf8geoscientificinformation39.60710039.039900-69.907600-69.0070002024-09-30T03:00:00Z2024-10-30T03:00:00ZOkuno, J., Hattori, A., Doi, K., Aoyama, Y., and Fukuda, Y.
