Abstract
An apparently complete 150m Oligocene sequence of pelagic sediment at equatorial Pacific DSDP Site 77B has been analyzed for stable-isotope and quantitative planktonic foraminiferal studies. Lower abundance of inferred warm-water species and enrichment of 18 O and 12 C in foraminiferal tests during the interval 29 to 32 my ago suggest cooler climate, lowered sea level, and significant volume of continental ice compared to earlier and later times in the Oligocene.-Authors
