We developed age models by visually comparing coral banding with seasonal d18O and d13C cycles. Dark regions of the coral X-ray positives corresponded with minima in d18O and d13C. We then associated local d18O and d13C minima with March, based on the mean Palau SSS and SST climatology. We converted samples to monthly resolution by performing linear interpolations between chronological anchor points.

Although empirically determined regression slopes are similar to published SST?d18OCRL fractionation values for P. lutea, in both instances, the per cents of explained variance in the regressions are small. This suggests that factors such as SSS are contributing to Palau d18OCRL variability in the pre-instrumental period.
