Last interglacial and penultimate glacial sea surface temperature anomalies: summary statistics for the region south of 40°S, resampled to 2000 year resolution ...
Southern Ocean marine sediments provide an important archive of Quaternary glacial-interglacial climate changes. Sea surface temperature (SST) reconstructions in the Southern Ocean depend exclusively on the fossils or geochemical signatures of planktic organisms, but the strengths of these SST proxi...
