DESCRIPTION: 
Seychelles coral oxygen-18 time series, data are monthly values 
of d18O from July 1846 to February 1995 from a 
3-m Porites lutea coral colony collected from Beau Vallon Bay 
(4 degrees 36.97 S, 55 degrees E, 7m water depth), Mahe Island, 
Republic of the Seychelles, in July 1995.

Stable isotopes were measured on untreated coral samples at the Scripps
Institution of Oceanography by D. Hunter and C. Charles on a Finnigan
MAT-252 gas source mass spectrometer with an automatic carbonate
preparation device. Values are in standard per mil notation relative to
PDB. Measurement precision is better than 0.08. Ages were derived from
annual variations in d18O in conjunction with annual density banding.
