Stable oxygen isotopes of Cibicidoides mundulus from sediment core MD13-3457, Alborán Sea, Marion Dufresne Cruise MD194

MD13-3457 is a calypso core taken from the East Melilla Mound Province, an area with multiple cold-water coral mounds. Taken from the nearby seafloor, and 20.31m long, it provides a perfect record of the common sedimentary deposits surrounding the mounds (off-mound). The age determination of core MD13-3457 is based on eight AMS 14C ages obtained from mixed planktonic foraminifera, and the stable oxygen isotopes here were used to set tie points in accordance with the global benthic stack LR04 of Lisiecki and Raymo (2005), in order to extend the age model of MD13-3457 to MIS5. Measurements were performed using a Finnigan MAT 252 gas isotope ratio mass spectrometer connected to a Kiel II automated carbonate preparation device, following Vienna Pee Dee Belemnite and NBS 19 standards (±0.09‰ d18O standard deviation).
