The core was collected vertically down the axis of maximum growth of the colony. The core was subsampled to obtain a bimonthly resolved time series of d18O. In this region, seasonal variations in d18O are due to temperature, interannual and multidecadal variations reflect the changes in salinity associated with the transport of the south equatorial current. Stable isotope analysis: Carbonate powders were reacted with 100% phosphoric acid at 75°C in an online carbonate preparation line (Carbo-Kiel-single sample acid bath) connected to a Finnigan Mat 252 masspectrometer. All values are reported in per mil relative to PDB by assigning a d18O value of -2.20 to NBS-19. Reproducibility was checked by replicate analysis of laboratory standards and is better than ±0.05 for d18O. Sampling resolution: The core top (1995-1900) was sampled at 2 mm increments. The base (1900-1832) was sampled at 1 mm increments. Age model: The heaviest isotopic value in any given year was assigned to August 31. All other age assignements are obtained through linear interpolation between these anchor points. St. Gilles reef, 21 02' S, 55 15'E. Porites sp., water depth 12.3m., core length 1.95m. ABSTRACT SUPPLIED BY ORIGINATOR: We have developed a new 163-year bimonthly coral d18O record from La Réunion (55°E, 21°S). Interannual variations in coral d18O are coherent with the Southern Oscillation Index but not with regional sea surface temperature (SST). Correlations with the global SST field suggest more negative seawater d18O (d18Osw) during La Niña years. We propose that the signal results from changes in the strength of the South Equatorial Current and the Indonesian throughflow, which carry low salinity water. Multidecadal variations in coral d18O are coherent with regional SST, but the sign is of opposite sense as expected from the coral d18O-temperature relationship. This requires multidecadal changes in salinity large enough to overprint the SST contribution in the coral d18O record. Our results suggest that multidecadal salinity variations result from modulations in the transport of the South Equatorial Current, which varies in response to the surface wind field and/or the Indonesian throughflow.
