Relative sea level in the Bahamas and western Australia. (a) Relative sea level in the Bahamas (solid pink; Abaco Island) and western Australia (solid grey; Houtman Abrolhos Islands) for a single global mean sea level (GMSL; dashed black line) history during the Holocene (8 ka to present). (b) Same as a, but for the LIG, in the case of a stable sea level highstand of +5 m from 125 to 120 ka. GMSL history is identical to that shown in Fig. 1(d).
