Extended Data Fig. 10: Changes in land surface as a function of changes in global mean sea level.

(a) Pixels occurring within the orange polygon were used to calculate the land/sea ratio in each time-slice map created by the ANICE-SELEN model. (b) Change in land to sea surface ratio in the Indonesian archipelago as modelled by the coupled ice sheet-topography model ANICE-SELEN for a subset of 9 glacial-interglacial cycles in respect to GMSL. Changes occurring from falling and rising sea level are plotted in blue and orange respectively – the hysteresis between falling and rising sea levels likely results from the delayed response of the solid Earth to changes in ocean water surface loading. (c) Slope of the land/sea surface ratio as a function of GMSL to highlight specific sea levels at which the rate of land exposure during sea level fall, or land flooding during sea level rise, is particularly fast with respect to the change in GMSL. Vertical blue shaded bars highlight the GMSL interval within which the change in ratios at GMSL fall is particularly fast. The map in (a) was plotted using the library Cartopy67 in Python. Outlines for countries are taken from ref. 68.
