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 Ni�a 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.","author":{"name":"Pfeiffer, M.; Timm, O.; Dullo, W.C.; Podlech, S"},"citation":"Pfeiffer, M.; Timm, O.; Dullo, W.C.; Podlech, S. 2004.
