a, Modern topography. b,c, Reconstructed palaeotopography at 8500 BP after removing Holocene sediment thickness, with sediment coring locations shown as white dots, which is obtained from ref. 29. d,e, GRD signals at 8500 BP using modern and palaeotopography, respectively. f, Difference between modern and palaeotopography GRD signals. g, RSL predictions at Taizhou (location shown in d) using both topographies. h, GRD signals for Taizhou predictions. i, GRD signal difference at Taizhou. j, Linear rate of GRD overestimation at each sea-level data location. k,l, Linear term estimates before and after correcting for GRD overestimation.
