inter-annual temperature variations are related to the SO activity, and, although relatively small, these will tend to magnify the SO signal in 
the coral d18O.

Recent changes in climate in the far western equatorial Pacific and their relationship to the Southern Oscillation; oxygen isotope records from massive corals, Papua New Guinea

The study was 4 samples per year but data is given as annual average values on NOAA web site. 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).

Sampling resolution is four samples per year, one sample in the middle of each density band. The 0.5 mm diameter, discrete point sampling strategy used in this study creates samples that are a homogeneous mixture of-26 (7 mm/year) to -20 (9 mm/year) days of skeletal growth, assuming a linear extension rate. (Quinn et al, 1993). Isotope sampling methods were also identical to Quinn et al. [1993], with new samples being midway between the original samples reported in that study.
