Central equatorial Pacific sea surface temperature (SST) anomaly is a critical predictor of basin-wide oceanographic and atmospheric effects of the El Niño-Southern Oscillation (ENSO) phenomenon. We employ two geochemical thermometers measured on coralline aragonite to reconstruct an independent proxy-based measure of central equatorial Pacific sea surface temperature anomaly. In addition, we assess the observational error associated with extraction of large-scale SST anomalies from δ18O and Sr/Ca measurements. On the basis of paired data for the 1981–1987 period, RMS error for the estimation of SST from Kiritimati coral δ18O is about 0.4°C, assuming no seawater δ18O influence; for Sr/Ca, the observational error is about 0.5°C. Singular spectrum analysis of the δ18O time series suggests that 1/3 of the variance is explained by SST anomaly and that this variance may be separated from other signals in the frequency domain. The interannual component of the δ18O record shares 70% variance with the interannual component of local SST anomaly estimates (ρ=−0.84) and correlates as highly with NINO3 region (150°W–90°W, 5°N–5°S) SST anomaly estimates; comparison of annual averages of the δ18O data with analyzed SST for 55 years suggests that the error in deriving annually averaged SST anomalies at Kiritimati is about 0.4°C. A global SST correlation analysis suggests significant correlation with the rest of the Pacific Basin and the tropical Indian and Atlantic sectors. The ocean-wide level of correlation achieved using the coral data is indistinguishable from that achieved using the NINO3 SST anomaly index and suggests that a few well-located coral reconstructions with low observational error may be sufficient to reconstruct the global SST anomaly field associated with ENSO activity.
