Abstract:
Microfossil and benthic Foraminifera isotopic data from DSDP Site 451 record paleoceanographic evolution and its major events since the late Miocene. Ostracod turnover from the Cytheropteron assemblage of the late Miocene-early Pliocene to a continuing increase in Krithe abundance probably indicates a deepening of some 1000 m water depth and a change in water properties from Intermediate Water to Deep Water, which may have been a result of the continuing subsidence of the West Mariana Ridge since the late Miocene. An abrupt 0.9% decrease in the delta (super 13) C of benthic foraminifera Cibicidoides wuellerstorfi during the period of late NN11 to NN12 represents the latest Miocene carbon shift in the West Pacific that has been documented globally.
