used the d18O cycle to count annual layers; assigned the high d18O extremes to Aug 1 of every year and interpolated linearly between these tie points. The largest d18O anomaly (late 1877) matches the most catastrophic monsoon failure on record

Authors suggest that ENSO dominates d18O variations on interannual timescales, while the Asian monsoon system drives decadal variability in d18O at this site
At the Seychelles, however, one would expect the seasonal temperature variability (of more than 2i¿½C) to dominate the nearly constant d18O of seawater
Furthermore, correspondence with an independent index of monsoon strength demonstrates that the coral successfully captures the large-scale aspects of Asian monsoon behavior
