Occurrence and isotopic composition (δ¹⁸O, δ¹³C) of benthic foraminifera in sediments from DSDP Leg 72, supplement to: Hodell, David A; Williams, Douglas F; Kennett, James P (1985): Late Pliocene reorganization of deep vertical water-mass structure in the western South Atlantic: Faunal and isotopic evidence. Geological Society of America Bulletin, 96(4), 495-503

Changes in the vertical water mass structure of the Vema Channel during the Pliocene have been inferred from benthic foraminiferal assemblages and stable isotopic analyses from three sites of DSDP Leg 72 (South Atlantic). Faunal and isotopic results from Sites 516A and 518 suggest that a major change occurred in deep-water circulation patterns in the late Pliocene near 3.2 Ma. Benthic oxygen isotopic records from Sites 516A and 518 show a characteristic increase in d18O...
