Abstract:
Stable oxygen and carbon isotope ratios measured on benthic foraminifera (Cibicidoides mundulus, Cibicidoides wuellerstorfi and Oridorsalis umbonatus) from the Miocene time interval from 15589 to 15964 ka at Leg 154 Site 927, Ceara Rise, tropical Atlantic. The sediment samples were washed and sieved at 63 µm and dry-sieved at 150 µm for benthic foraminifera picking. We performed stable isotope analyses (ẟ18O and ẟ13C) at Bremen university, using a ThermoFisher Scientific MAT 253plus gas isotope ratio mass spectrometer with a Kiel IV automated carbonate preparation device. This gives ẟ18O values with a standard deviation of house standard (Solnhofen limestone) over measurement period of 0.07 ‰ and ẟ13C values with standard deviation of house standard (Solnhofen limestone) over measurement period of 0.03 ‰. The number of specimens used for each measurement is specified. For the species-specific ẟ18O and ẟ13C values correction, we used the calibration given in the supplement table S3 from Westerhold et al. (2020, DOI: 10.1126/science.aba6853), and the average is calculated from the corrected values. The composite depths and age model presented are from this study.
