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.
