Evolution of the southwestern Pacific surface waters during the early Pleistocene
We present alkenone-derived sea surface temperature (SST) records from the New Zealand/Tasmania sector of the Southern Ocean (ODP Sites 1171 and 1125) during the Early Pleistocene (c. 1.7 to 0.7 Ma). Our data show that the subantarctic surface waters (ODP Site 1171) cooled by c. 4 °C and reached nea...
