Abram, N. J., Dixon, B. C., Rosevear, M. G., Plunkett, B., Gagan, M. K., Hantoro, W. S. and Phipps, S. J.: Optimized coral reconstructions of the Indian Ocean Dipole: An assessment of location and length considerations, Paleoceanography, 30(10), 1391–1405, doi:10.1002/2015pa002810, 2015.

The paper does not assess correlation between d18O and SST due to lack of instrumental SST and upwelling. My assessment of the data shows a 0.36 correlation between coral D18O and coral Sr/Ca suggesting temp rependcany is low. This suggest the coral d18O is primary a salinity signal. note the authors also provide a coral d18Osw data set.
