(Supplementary Table 1) Results of U-Th analysis

* Sample ID Dating can be slightly different to the corresponding Sample ID Palaeo (Supplementary Table 2), as the dating sample in some cases is a subsample of a larger coral section that was sampled for palaeoclimate.** Woods Hole Oceanographic Institution (WHOI), Australian National University (ANU), University of Oxford (OX).*** U-Th ages are reported as kyr before the present relative to AD 1950.A, B: U-Th analyses were performed on different parts of the same coral specimen.detr. corr.: Detritial corrected.Results of powder X-ray diffraction (XRD) analysis are shown in Supplementary Table 2.The corals are massive and robust/branching Isopora palifera/cuneata colonies.
