Bayesian age-depth model for profile B4 according to Blaauw and Christen (2011). Top left: The log-likelihood of the model fit for the saved iterations of the model, top middle: prior and posterior distribution of accumulation rate, and top right: prior and posterior distribution of the autocorrelation in accumulation rates (memory) and the time gap (hiatus size) at the end. Bottom panel shows the calibrated 14C dates (transparent blue) and the age-depth model (darker greys) indicate more likely calendar ages; grey stippled lines show 95% confidence intervals; red curve shows single ‘best’ model based on the mean age for each depth
