    Abstract

    Stable oxygen and carbon isotope measurements (δ18O and δ13C) of planktonic and benthic foraminifers were conducted to assess the temperature history and circulation patterns over Shatsky Rise during the Paleocene and Eocene. A record of Mg/Ca for benthic foraminifers was also constructed in order to better determine the relative influence of temperature, salinity, and/or ice volume upon the benthic δ18O record. Isotopic analyses were carried out on several planktonic taxa (Acarinina, Morozovella, Globigerinatheka, Praermurica, and Subbotina) as well as several benthic taxa (Nuttalides, Oridorsalis, Cibicidoides, Gavelinella, and Lenticulina). Elemental analyses were restricted to three benthic taxa: Nuttalides, Oridorsalis, and Gavelinella. All specimens were derived from the composite sediment section recovered from Ocean Drilling Program Site 1209 on the Southern High of Shatsky Rise.
