Summary: Carbon and oxygen isotope values and planktonic/benthic ratios are presented for Middle Miocene (11-17.5 Ma) foraminifers deposited at Hole 744B of the Kerguelen Plateau. Major features of the isotope records are similar to those of other Middle Miocene open-ocean records. The portion of the sequence containing the major Middle Miocene delta18O increase (between 60 and 52 m below seafloor) is a relatively condensed zone characterized by low planktonic/benthic ratios and several hiatuses. The isotopic record is of sufficiently high resolution to date the delta18O minima and the delta13C maxima to within 200,000 yr. Ages determined by oxygen and carbon isotope stratigraphy are similar to those obtained using diatom, radiolarian, and paleomagnetic stratigraphy, but are approximately 1 m.y. younger than those determined by strontium isotope stratigraphy. The average middle Miocene sediment-accumulation rate for Hole 744B is approximately 4 m/m.y. (Auth. mod.)
