Alibert and McCulloch (1997) report "A least squares fit was then calculated between measured Sr/Ca ratios and the instrumental SSTs using a Williamson regression, with a reproducibility of 0.00002 (2sigma) on Sr/Ca ratios (equivalent to approximately 0.3 deg C) and an error of 0.1 deg C (1sigma) on measured temperature" and in their conclusions "Analytical precision and reproducibility between different Porites corals are better than +/- 0.3 degC (2sigma)." Hendy et al. (2002) data are archived as a calibrated Sr/Ca SST composite, with the 95% confidence interval of the seven individual pentannual Sr/Ca coral records that went into the composite. From Hendy et al. (2002): "average Sr/Ca sd between replicated coral samples is equivalent to 0.15 deg C (sd = 4.6 Greek Letter Mumol/mol, total n = 550; internal laboratory standard, sd = 3 Greek Letter Mumol/mol, n = 21)." For the Hendy et al. (2002) composite "Sr/Ca were normalised to 1985-1860 by subtracting the mean Sr/Ca value for this interval" (verified with lead author Erica Hendy). In McGregor et al. (2015) the Hendy et al. (2002) "SrCaSST_anomaly data were converted to a pseudo SST, whereby to estimate absolute SST the mean ERSSTv3b value (26deg C) for 148E, 18S (the nearest grid square to the corals location) was added to the SrCaSST_anomaly". ; paleoData_units changed - was originally deg C; climateInterpretation_seasonality changed - was originally Annual| | ||
