Summary: The planktonic foraminiferal zonation of 1986, which was defined for the southwestern sector of the temperate South Pacific Ocean, was successfully extended to the temperate sequences at Site 704. The zonation is based on first and last appearances of globorotalids, principally Globoconella species, which are indigenous to temperate surface-water masses. Most of the first and last appearances at ODP Site 704 are diachronous with those in the warmer temperate to subtropical South Atlantic, North Atlantic, and South Pacific oceans. The upper Miocene, upper Pliocene, and Quaternary sequences are punctuated by frequent incursions of subantarctic and polar assemblages of planktonic foraminifers. It is assumed that the appearance of an assemblage dominated by sinistral Neogloboquadrina pachyderma means that the Polar Front has migrated northward, but to an unknown position. The upper Miocene sequence contains five incursions between 6.5 and 5 Ma and the upper Pliocene and Quaternary sequence contains 16 events since 2.47 Ma. These are minimum estimates because the number of observed events will probably increase with higher sample density and use of quantitative methods to reveal more subtle events. (Auth. mod.)
