Summary
Abstract: This data set consists of Globigerina bulloides Mg/Ca as a paleotemperature
proxy. Indicated glacial-interglacial changes in sea surface temperature (SST)
are about 4°C cooler in the Subantarctic Indian Ocean and 2.5°C cooler in the
Subantarctic Pacific.

Mg/Ca-based SST estimates and d18O determinations are then used to generate
site-specific seawater d18O records.

Data precision: Mg/Ca, ... View entire text
