Figure F23. Glacial-interglacial cycles in the late Pliocene, Site 532. A. Heavy line = deepwater oxygen isotopes (Uvigerina). Other lines are obliquity band- and precession band-filtered sequence (based on peak width in spectrum). B. Spectrum of oxygen isotope record, carbonate content, and opal at Site 532, late Pliocene. Data are from Sancetta et al. (1992). (Ages adjusted by matching to scale of Bickert et al., 1997).
