MARGO LGM planktonic oxygen isotopic data

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.
