Abstract:
Here we present same sample measurements of C. wuellerstorfi and U. proboscidea stable carbon isotopes from ODP sites 883 and 887. Samples were freeze dried, weighed, soaked in water for 24 hours to disaggregate, and wet sieved using a 150 μm mesh sieve. Samples were then dried at 40°C. Select genera and species were picked and comprehensively counted from the 150–355 μm fraction. Cibicidoides wuellerstorfi and Uvigerina probuscidea were both measured in 84 samples. Specimens selected for isotopic analysis were cleaned with 70 μL ethanol and sonicated for 30 seconds. Ethanol was drawn off with a pipette, and specimens were dried overnight at room temperature. Isotope ratios were quantified at the Brown University stable isotope facility with a Finnigan Mat 252 with Carbonate Kiel III autosampler, in which individual samples were reacted with 70°C H3PO4.
