Figure 25. Benthic oxygen isotope profiles from ODP drill sites along the California margin. Site 893 data from Kennett et al., 1995; Site 1017 data from Kennett et al., Chap. 21, this volume; Site 1014 data from Hendy and Kennett, Chap. 7, this volume; Sites 1011, 1012, and 1018 data from Andreasen et al., Chap. 8, this volume; Sites 1019 and 1020 data from Lyle et al., Chap. 11, this volume. Offsets in the isotope curves are primarily because of the temperature profile through the thermocline.
