We explore this potential using a monthly resolved, 65-year record of  skeletal d18O and Sr/Ca variations in a Porites coral from Espiritu Santo,  Vanuatu. We demonstrate that El Nino-Southern Oscillation-related climate  variability strongly influences coral d18O at Santo through local salinity  changes associated with the position of the South Pacific Convergence Zone  and the movement of its associated salinity front. Such a demonstration  provides the \"ground truth\" data that can be used to place paleoclimate  variability estimated using existing fossil coral records from this region  into a modern conceptual framework. We also evaluate different methods of  combining coral d18O and Sr/Ca to reconstruct SSS and conclude that the  coral d18O anomaly time series provides the best fit to recent in situ  SSS data at Santo.","author":{"name":"Kilbourne, K.H.; Quinn, T.M.; Taylor, F.W.; Delcroix, T.; Gouriou, Y"},"citation":"Kilbourne, K.H.; Quinn, T.M.; Taylor, F.W.; Delcroix, T.; Gouriou, Y. 2004.
