Abstract:
Accelerator mass spectrometry (AMS) radiocarbon dates were obtained for eight bulk sediment samples (pre-treated with HCl) at the NERC Radiocarbon Facility in East Kilbride. An age-depth model was constructed through Bayesian modelling using a _P_sequence_ deposition model in OxCal v.4.2.4, which included an “event free depth scale” (Staff et al., 2011) to account for the instantaneous deposition of a 4 cm thick tephra layer and interpolated ages every 1 cm.
