Abstract
    The relative proportions of the main microfossil groups (diatoms, nannofossils, foraminifera, silicoflagellates and radiolaria) in the uppermost undisturbed Pleistocene sediments at selected sites drilled by the Glomar Challenger in the southeast Indian Ocean (Leg 28) and southwest Pacific Ocean (Legs 21 and 29) are demonstrated. By relating these to the present-day water mass overlying each site, the faunal microfossil expression of the sediments forming beneath different types of water is recognised. The relative proportions of the same microfossil groups are plotted for the complete section drilled at these same sites. By comparing these diagnostic sedimented faunas with older faunas at each site, oceanographic reconstructions for the major features in the developments of the southeast Indian Ocean and southwest Pacific circulations are presented for the period from the Paleocene to the Pleistocene.
