AMS 14C age determination for 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 to compare the common sedimentary system surrounding the mounds (off-mound) with cores taken from the cold-water coral mounds themselves. The age determination of core MD13-3457 is based on eight AMS 14C ages of obtained from mixed planktonic foraminifera, and the stratigraphy was extended through tie points relating stable oxygen isotope (d18O) composition data of epi-benthic foraminifera from this core to the LR04 benthic stack by Lisiecki and Raymo (2005). Raw ages are given, as well as a calibration using the IntCal20 calibration curve (Reimer et al., 2020) and modelled reservoir ages of Butzin et al. (2017) extracted with Palaeo Data View (PDV) software (Langner and Mulitza, 2019). Age error of the tie points was conservatively set to 4 kyr following discussions in Lisiecki and Raymo (2005).
