(Table 3) Late Miocene silicoflagellates drom DSDP Hole 90-594

Miocene silicoflagellates, dominated by Mesocena, are identified and correlated from Site 594 to other Deep Sea Drilling Project sites. Relative paleotemperature values from silicoflagellates at Site 594 are very low, supporting the evidence of the associated cold-water, low-diversity Coccolith assemblages. The greatest abundances of Mesocena diodon nodosa yet recorded occur at Site 594, which is near the present Subtropical Convergence. Similarities in the ecostratigraphic records between Chatham Rise (Site 594) and the Falkland Plateau (Site 329) in the late Miocene indicate widespread events within the circum-Antarctic water mass.
