age model was established on the basis of the pronounced seasonal cycle in the Sr/Ca record. The maximum (minimum) Sr/Ca was tied to March (September), which is on average the coolest (warmest) month in the study area. The coral d18O and Sr/Ca time series were linearly interpolated between these anchor points using the Analyseries software [Paillard et al., 1996] to obtain monthly proxy time series.

Hetzinger 2006 is  the calibration paper and Hetzinger 2010 is the full reconstruction with interpretation. Confirmed the data reported for both studies on NOAA web site is the identical.

0.06% (1s) (n = 367) 2 standards after every 10 samples

overlapping parts of sampling transects along different thecal walls were compared for proxy validation. The reproducibility is excellent (RSD is 1.88% for d18O; n = 24)

Both geochemical proxies show a significant correlation with instrumental SST over a 41-year time period on both monthly and mean annual scales. We obtained proxy-SST calibrations that are consistent with previously published studies using other coral species from different regions. Hetzinger 2006 10.1029/2006GC001347

Correlation and regression assesed with SODA SST, ERSST V2.0, and local air temperature for 1958-1999 for monthly values, extreme values only (max-min mehtod), and annual mean. ERSST extreme values had the correlation, this could be due to subannual dating uncertaincies and linear interpolation to monthly values. Calibration detailed in Hetzinger 2006, 10.1029/2006GC001347
