Oxygen and carbon isotope stratigraphies are presented for planktonic and benthic foraminifera from Miocene sediments of the tropical Indian Ocean (DSDP Sites 214, 216, 237, 238) and placed into a biostratigraphic framework. Approximately 1000 foraminiferal analyses were performed to determine both oxygen and carbon isotopic ratios. The species analyzed were Globigerinoides sacculifer and Dentoglobigerina altispira (shallow-dwelling planktonic), Globoquadrina venezuelana (deep-dwelling planktonic), and Oridorsalis umbonatus (benthic). We identified a number of isotopic signals which appear to be synchronous with previously recognized signals in the Pacific Ocean, and thus provide useful tools for chronostratigraphic correlations.
The oxygen isotope record is dominated by...
