| contents | Oxygen and carbon isotope records are presented for the planktonic foraminifers Dentoglobigerina altispira and Globigerinoides sacculifer (shallow-dwelling species) and Globoquadrina venezuelana (deep-dwelling species) from Miocene sediments at two Ocean Drilling Program sites, located at depths of near 3000 m, in the western (Site 709) and eastern (Site 758) tropical Indian Ocean. The planktonic isotope record at Site 709 is compared with the benthic isotope record obtained at this site by Woodruff et al. (1990, doi:10.2973/odp.proc.sr.115.147.1990). The isotope stratigraphy is related to the biostratigraphy and the available magnetostratigraphy at the sites. Despite varying sampling density, incompleteness of isotopic records, and the condensed (or even disturbed) nature of parts of the sequences, a number of chronostratigraphic isotopic signals previously recognized in the equatorial Pacific and at other tropical Indian Ocean sites are identified. |
