Abstract:
The dataset contains an age-depth model, dry bulk density measurements and sedimentation rates for the Kasten Core M144 KC5-6, collected in the central western Aegean Sea (Eastern Mediterranean). Dry bulk density (DBD) was estimated for every 1cm sample slice, by dividing dry bulk sediment mass by sample volume. Sedimentation rates were calculated for each sample depth through the age-depth model, which is based on radiocarbon dating and Bayesian modelling. Eleven radiocarbon dates (14C) were taken along the 272 cm core, obtained from different depths. Planktic foraminifera (Globigerinoides ruber white) tests, isolated from the 250 to 315 µm fraction, were analysed, by using the accelerator mass spectrometry (AMS) at the NOSAMS facility at Woods Hole Oceanographic Institution. Considering the globally averaged mixed-layer reservoir age of ~400 yr., we calculated the age depth model through Bayesian statistics applying the R-code package rbacon (version 3.1.1) using the calibration curve Marine20 to transform 14C dates to calendar ages.
