This sample was collected alive at < 1 m water depth (Quinn 1993). Comparison of the d180 with SST and rainfall records indicates a correlation of 0.71 and 0.54, respectively, over the 13-year interval where data overlaps (Fig. 2). Just as in the precipitation and SST comparison, the correlation is much higher at the annual cycle (coherence of 0.95). There is also a slight suggestion of coherence at the El Nino time scale, but the calibration time series is too short to draw any definitive conclusions. Since the 0.71 correlation between SST and d180 explains only half the variance in the SST record, other factors are obviously responsible for the d180 variations. (Quinn 1996)

Quinn et al., 1996, SST/d180 calibration for Platygyra has been estimated at 0.266 per mil d18 per degree C [Weber and Woodhead 1972]

The original meta data on NOAA states there are four files, vanuatu.xls (Microsoft Excel Workbook), vanuatu.2yr.txt, vanuatu.4yr.txt, vanuatu.annual.txt (Tab-delimited text), but these appear to be missing from NOAA web site now. I have a copy archived of these files (kdelong@lsu.edu).
