Dataset provided as supplement to Richardset al. (2023).Geodynamically corrected Pliocene shoreline elevations in Australia consistent with mid-range projections of Antarctic ice loss, Science Advances , in review. bayesian_modelling_output --- directory containing posterior samples from Bayesian GMSL inversion and derived quantities, e.g., mean, median, and standard deviationof dynamic topography, GIA, and GMSL. deconto_etal_2021_refit --- De Conto et al., (2021; Nature)model runsfiltered on the basis of their original Mid-Piiocene Warm Period (MPWP) GMSL constraint and this study's revised estimate. pliocene_to_recent_dynamic_topography_outputs --- gridded output of predicted Pliocene-to-Recent changes in dynamic topography, which take into account plate rotation and geoid and dynamic topography impacts on the sea-level equation and shoreline migration (Austermann & Mitrovica, 2015, GJI). pliocene_to_recent_GIA_outputs ---gridded output of predicted Pliocene-to-Recent changes in glacial isostatic adjustment. Grids show predicted relative elevation change ofanMPWP sea-levelmarker, with net GMSL changesubtracted. present_day_dynamic_topography_outputs --- gridded output of predicted present-day dynamic topography for independently constrainedthermochemical density models (see Richards et al., 2023, EPSL for further details). sea_level_constraints --- input MPWP sea-level marker dataset. thermal_expansivity_profile --- fitted pyrolite-based thermal expansivity profile.
