Summary

Abstract

Appendix I - Radiocarbon data reported as D14C from the sample series extracted from the Guam coral core with the validated date of formation. The reported Fraction modern values were corrected online (during AMS measurement) and F14C is used to unambiguously symbolize fractionation corrected values [Reimer et al., 2004]. A partitioned sample provided a robust and sample-specific d13C value.
