Figure F17. Contoured benthic delta13C vs. time and water depth based on analysis of Sites 1088 (2082 m), 1090 (3702 m), and 1089 (4621 m). Note the sharp vertical delta13C gradients between middepth Site 1088 and the deeper sites during glacial periods and subtle gradients during interglacial stages. The SPECMAP delta18O record is shown for reference to oxygen isotope stages (modified after Hodell et al., 2002).
