basis: 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.
direction: positive
inferredMaterial: seawater
integrationTime: 1
integrationTimeBasis: 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
