U.S. Geological Survey (USGS) scientists combined coral-based estimates of \u0394R, using statistical modeling, to reconstruct millennial-scale variability in \u0394R at locations on the FKRT with (\u201cnearshore\u201d) and without (\u201copen ocean\u201d) terrestrial influence. USGS scientists also used the models to provide temporally-explicit estimates of \u0394R that can be used in radiocarbon calibrations of marine samples from the region.
