Cores are located in the sub-Arctic Pacific (ODP Site 882) and the sub-Antarctic Atlantic (ODP Site 1090). The percentage of the C37:4 alkenone relative to the total abundance of C37 alkenones (%C37:4) in these records is an additional tracer that can be used to infer variations in the meridional extent of polar and subpolar conditions through time. ABSTRACT SUPPLIED BY ORIGINATOR: The cold upwelling "tongue" of the eastern equatorial Pacific is a central energetic feature of the ocean, dominating both the mean state and temporal variability of climate in the tropics and beyond. Recent evidence for the development of the modern cold tongue during the Pliocene-Pleistocene transition has been explained as the result of extratropical cooling that drove a shoaling of the thermocline. We have found that the sub-Antarctic and sub-Arctic regions underwent substantial cooling nearly synchronous to the cold tongue development, thereby providing support for this hypothesis. In addition, we show that sub-Antarctic climate changed in its response to Earth's orbital variations, from a subtropical to a subpolar pattern, as expected if cooling shrank the warm-water sphere of the ocean and thus contracted the subtropical gyres.
