The 44 cm peat sequence spans approximately 5.6 to 1.0 ka BP and was sampled at 1 cm intervals. The chronology is constrained by six AMS radiocarbon dates obtained from bulk peat organic carbon and calibrated using the IntCal20 calibration curve; an age-depth model was constructed using the Bayesian Bacon approach.
