Figure F5. Compilation of benthic oxygen isotope data for the Cenozoic (Zachos et al., 2001a). Also shown is the time window investigated during ODP Leg 199 and the position of three major events targeted by the leg. P/E = Paleocene/Eocene boundary and its associated thermal event. Oi-1 is approximately at the E/O boundary and marks the first major Antarctic glaciation. Mi-1 is near the O/M boundary and marks the beginning of the development of the Neogene cryosphere.
