Extended Data Table 2 GIA model details

From: Mass balance of the Antarctic Ice Sheet from 1992 to 2017

  1. Regional changes in mass associated with the GIA signal were determined from the model data.
  2. Regional changes in mass associated with the GIA signal were calculated as an indicative rate using spherical-harmonic degrees 3 to 90.
  3. aMain publication5,8,9,10,11,12,13,14,15,16 listed; supporting publications are provided in Supplementary Table 1.
  4. bModel from main publication unless otherwise stated. Comma-separated values refer to properties of a radially varying (1D, one-dimensional) Earth model: the first value is lithosphere thickness (km); other values reflect mantle viscosity (×1021 Pa s) for specific layers; see relevant publications for details.
  5. cIce model covers at least the Last Glacial Maximum to present, unless otherwise indicated.
  6. dGIA model details: SH, spherical harmonic (maximum degree indicated in parentheses); FE, finite element; C, compressible; IC, incompressible; RF, rotational feedback; SG, self-gravitation; OL, ocean loading; x, feature not included; UQ, uncertainty quantified.
  7. eRSL, relative sea-level data; GPS rates were all corrected for the elastic response to contemporary ice mass change.
  8. fDifferent to ICE-6G_C in Antarctica, owing to the use of BEDMAP21 topography in that region.
  9. gModel relates to GIA in the northern Antarctic Peninsula (nAPIS) only.
  10. hModel relates to GIA in the Amundsen Sea (AS) embayment only.
  11. iEarth model from ref. 24.
  12. jIce model from ref. 88.
  13. kGIA model from ref. 89.
