Radiocarbon dating was undertaken at the UMS-ARTEMIS Facility (CNRS-CEA Saclay, France) using a Pelletron 3MV AMS on 8 mg of well-preserved calcareous test samples of planktonic foraminifera (monospecific samples of Globigerinoides ruber, Globigerina bulloides and Globigerina inflata and a mix of planktonic foraminifera for one sample) in the size fraction >150 µm (Table 1). The age models for the cores were derived from the calibrated planktonic ages by applying a variable sea-surface reservoir ¹⁴C correction (Siani et al., 2000, 2001) and using INTCAL20 (Reimer et al., 2020) calibration curve in the Oxcal 4.4 software (Bronk Ramsey, 2009).
