Saraswat, R., R. Nigam, S. Weldeab, A. Mackensen, and P.D. Naidu. 2005. A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera. Geophys. Res. Lett., 32, L24605.
Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last ~137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record the equatorial Indian Ocean SST was ~2.1°C colder during the last glacial maximum as compared to present times. The data further shows that the surface equatorial Indian Ocean was comparatively warmer during isotopic stage 5e than at present (~29.9 vs ~28.5°C). Comparison of the equatorial Indian Ocean SST with the Antarctic dD and Greenland d18O records, shows that the major high-latitude cooling/warming events are also present in the equatorial Indian Ocean SST variation record. Similarity between the equatorial Indian Ocean SST and the equatorial Pacific SST suggests the possibility of a common mechanism controlling the SSTs in both the equatorial Indian Ocean and the Pacific Ocean.
