Abstract

The distribution of radiolarian assemblages identified by Q-mode factor analysis of radiolarian microfossils in surface sediments from low latitudes in the Pacific Ocean reflects their associations with surface water masses. Downcore fluctuations of these radiolarian assemblages at two sites, RC10-65 and V19-29, indicate changes in circulation in the eastern equatorial Pacific during the past 500,000 yr. Fluctuations in the importance of upwelling along the coast of Preu and in the Equatorial undercurrent have not been consistent with glacial/interglacial changes in ice volume throughout the late Quaternary.
