ANA2003: G. bulloides, based on coretop data from Elderfield and Ganssen, 2000, Nature

Seawater ?18O (?18Ow in ? vs. V-SMOW) was estimated from Mg/Ca-derived calcification temperatures and ?18O of foraminiferal calcite (?18Oc in ? vs. PDB) by rearranging the isotopic paleotemperature equation of Shackleton (1974) (T = 16.9 ? 4 i¿½ (?18Oc ? ?18Ow)) and solving for ?18Ow. A V-SMOW vs. V-PDB correction of ?0.20? was applied, consistent with the correction factor common at time of publication of the Shackleton equation (see Bemis et al., 1998). Based on an analytical error of i¿½0.06? for ?18Oc and a combined analytical and calibration error of i¿½1 i¿½C for T (Mg/Ca), the uncertainty for reconstructed ?18Ow is estimated as i¿½0.26?.
