We conclude that Cenozoic benthic δ18O primarily reflect considerable deep-ocean temperature variation and that tropical planktonic δ18O afford the best record of Cenozoic ice volume. The planktonic composite indicates the presence of a significant ice budget for the past 40 m.y. The difference between the benthic and planktonic δ18O composites suggests that low-latitude production of warm saline bottom water dominated Tertiary thermohaline circulation.
