Calcium carbonate contents and oxygen and carbon isotopic compositions of planktic and benthic foraminifera in sediments at DSDP Site 85-575
Data on the composition of benthic foraminiferal faunas at Deep Sea Drilling Project Site 575 in the eastern equatorial Pacific Ocean were combined with benthic and planktonic carbon- and oxygen-isotope records and CaCO3 data. Changes in the composition of the benthic foraminiferal faunas at Site 57...
