"We obtained excellent replication of...regions of overlap between cores and in slabs where two transects were sampled"

Ages were determined independently for the two cores on the basis of seasonal d13C variability, which is supported by radiometric and density-banding observations of young Tarawa corals.  We normalized the records, spliced them together using diagnostic density and isotopic patterns, and interpolated them to monthly resolution for statistical analysis

At Tarawa, results from an ongoing monitoring program confirm that intenst rainfall alters the d18O and salinity of the surface mixed layer.  Shallow-growing corals incorporate this isotopic shift in the d18O of their aragonite skeletons.

Correlation of Tarawa d18O record with local SST on monthly (0.62), seasonal (0.67) and annual (0.78) timescales compared to local rainfall on monthly (0.39 or 0.59), seasonal (0.47 or 0.66), and annual (0.59 or 0.80) timescales.
