Estimates of the change in surface seawater d18O (d18Osw) between the Last Glacial Maximum (LGM) and Late Holocene (LH) are derived from homogenous data sets with rigorous age control, namely MARGO sea surface temperature (SST) estimates and oxygen isotopic ratios (d18O) of planktonic foraminifers.
Propagation of uncertainties associated with each proxy allows the identification of robust patterns of change in d18Osw. Examination of these patterns on a regional scale highlights which changes in surface currents and hydrological cycle are consistent with both planktonic isotopic data and reconstructed SST.
