Sr/Ca data to monthly SST from the 2i¿½ i¿½ 2i¿½ grid square centered on 4i¿½N, 172i¿½E from the extended reconstructed SST version 3b (ERSSTv3b) data product [Smith et al., 2008; ttp://www.esrl.noaa.gov/psd] [?] Annual Sr/Ca maxima were tied to the coolest points in the SST record using Analyseries [Paillard et al., 1996]. The resulting spacing of Sr/Ca data remained relatively constant throughout the record, and the chronology was verified against growth band counts from the X-radiograph. After converting depth to time in Analyseries, Sr/Ca were interpolated to six equally spaced samples per year using ARAND time series analysis software [Howell, 2001], corresponding to bimonthly resolution for the length of the record.

ENSO dominates d18O on interannual timescales. On decadal and longer timescales, larger scale processes such as PDO likely influence d18O.
The full Butaritari coral Sr/Ca and d18O (Figures 3b and 3c) are well correlated with SST from the 2° x 2° grid cell centered on 4°N, 172°E in ERSSTv3b (R = 0.58 for Sr/Ca and 0.39 for d18O, p < 0.05 on detrended bimonthly data).
