Figure F2. Cross-plot of carbon and oxygen values, Hole U1318B. For comparison, the isotopic range of potential sources (A–C) and bulk mound sediments from Hole U1317E (D) (Takashima et al., 2006) are also shown. A = benthic foraminifer Cibicidoides sp. from ODP Site 982, B = planktonic foraminifer Globigerina bulloides from Hole U1317E (Sakai et al., 2009), C = Cretaceous chalk from southeast England (Jenkyns et al., 1994).
