The geochemical age model was shifted within error of the 230Th dates (Table DR1) to match the timing of the 1578 CE El Nii¿½o event known from historical records (Ortlieb, 2000). The U-th dates have errors of 2-4 year for the fossil corals and the 20th century corals had U-Th erros of 3-5 years.

~1-2 months in any given year, no errors given for annual chronology

Thermo-Finnigan MAT253 Isotope Ratio Mass Spectrometer (IRMS), with a  Kiel IV Carbonate Device, and on a Thermo-Finnigan Delta V Plus IRMS  with Gasbench II (GB II) connected to a Conflo IV, both at the Analytical Laboratory for Paleoclimate Studies (ALPS) at the Jackson  School of Geosciences, University of Texas at Austin. Longterm precision for this instrument of 0.06? for d18O and 0.03? for d13C. The precision of the  GB II/Delta V Plus IRMS is  long-term precision for this instrument of  0.07? for d18O and 0.03? for d13C. Internal standards testing confirms that isotopic values are consistent between the two instruments.
