  1. Minimum and maximum range on a 95% confidence interval of calibrated ages of all replicates per site and depth increment. Calibration was performed using OxCal v4.4.284 by using the IntCal20 international calibration curve85 (methods). The number of replicates is reported in brackets. All calibrations and age probabilities for individual samples are presented in Supplementary Fig. 1. Average F14C values (as range when n = 2 and with analytical error when n = 1) with one standard deviation corresponding to the calibration ages. All values of the bulk SOC are presented in Supplementary Table 2.
