Twenty short cores were recovered from the northern Scott Plateau (water depths ca 3200 m) and the southern slope of the Java Trench (water depths 4950-5790 m) by R.V. Valdivia in 1977; selected cores have been studied in detail. About 55 species of benthonic foraminifera were identified on the plateau, but only half as many in the trench. Only deep-water forms occur in the trench, suggesting an absence of transport from shallower depths. Fragile agglutinating forms are confined to the surface sediments, or are totally absent. The planktonic foraminifera from the plateau generally belong to tropical associations. The assemblages show that the Holocene-Pleistocene boundary lies at about 60 cm in the cores, and that carbonate solution is more marked above than below the boundary.
