Least squares linear regression of monthly Sr/Ca to SST shows a strong, significant correlation (r2 = 0.77, p < .0001), with root mean square residuals of 0.9 °C. 3-year averaged (binned) Sr/Ca for wet (Sep-Nov) and dry (Jan-Mar) seasons separately captures SST variability at interannual time scales (Sr/Ca RMSR = 0.42 °C and 0.70 °C for wet and dry seasons, respectively). Coral d18O correlates weakly to SST at seasonal and interannual time scales for wet and dry seasons, with significant anomalies (d18O RMSR = 2.4 °C and 1.65 °C, respectively). Correcting the SST influence on coral d18O using paired Sr/Ca values provides estimates of d18O of seawater (d18Osw). 3-year averaged d18Osw during the wet season shows a significant correlation to local precipitation (r2 = 0.54, p = 0.01). These results show that coral Sr/Ca in this location accurately reflects SST at a number of timescales, and that seawater d18O composition in the wet season is controlled by local precipitation, largely unmodified by ocean circulation during the winter monsoon. This study highlights the sensitivity and utility of coral geochemistry in this region for reliably reconstructing SST and monsoonal precipitation. #------------------ # Funding_Agency #
