Carbon and oxygen isotopic determinations have been made of 29 species of Recent Indian Ocean planktonic foraminifera. Fourteen core-top samples were used and as many as 18 species were chosen from a single core-top sample. The δ13C of the foraminifera was compared with that of total dissolved CO2 (ΣCO2) and of calcite precipitated in isotopic equilibrium with ΣCO2. The foraminiferal calcite is always at least 1.2‰ less than the value estimated for equilibrium calcite. This carbon isotopic disequilibrium suggests the partial utilization of 13C-depleted metabolic CO2. The calcite tests of several species, however, have δ13C values which are similar to the δ13C of ΣCO2 in seawater. This relationship suggests that important paleohydrographic information may be obtained from carbon isotope records based on analyses of several foraminiferal species from single deep-sea sediment samples.
