Surface and sub-surface seawater temperature reconstruction using Mg / Ca microanalysis of planktonic foraminifera Globigerinoides ruber, Globigerinoides sacculifer and Pulleniatina obliquiloculata.

Using Mg / Ca paleothermometry from the planktonic foraminifera Globigerinoides ruber from the past 500 k.y. at Ocean Drilling Program (ODP) Site 871 in the western Pacific warm pool, we estimate the tropical Pacific climate sensitivity parameter (λ) to be 0.94 — 1.06 °C (W m − 2) − 1, higher than that predicted by model simulations of the Last Glacial Maximum or by models of doubled greenhouse gas concentration forcing.

The annual average SST proxy used δ18O in planktonic foraminifera in a radiocarbon - dated 1990 Bermuda Rise box core.

Given the inconsistent SST reconstructions obtained using existing paleotemperature equations and the recently identified parameters controlling shell d18O values, there is a clear need to reexamine the temperature: d18O relationships for planktonic foraminifera.»
