Coral Sr/Ca (d18O) records are well correlated to each other and to the instrumental SST record (1967-1992), especially in terms of differences in the mean values of 25-year SST records (~0.2C, Sr/Ca-SST; 0.6C, d18O-SST).  The average error associated with the coral Sr/Ca-SST (d18O-SST) of any particular month, season or year is ~0.8C (1.1C), 0.6C (0.8C) and 0.5C (0.6C), respectively.  \"\"Stacking\"\" or averaging the individual proxy records reduces the error between observed and predicted SST, although the reduction is small for coral Sr/Ca.  Excellent reproducibility among the coral proxies implies that reliable climate records can be generated from a single coral core and that coral Sr/Ca-SST records are not compromised, beyond the errors stated herein, by non-temperature-related biological effects.","author":null,"citation":"Stephans, C., T.M.
