This dataset comprises the age-depth model for Lake Lama (Taymyr peninsula), based on the Accelerator Mass Spectrometry radiocarbon dating of 19 samples from the sediment core PG1341 with the additional use of two dated woody remains from Andreev et al. (2004). The age-depth model was established using the R package 'Bacon', based on the IntCal13 calibration curve and dates back 23.000 years. The dataset is the output of the bacon run and contains information about the depth of the sediment core and the corresponding minimum, maximum, median, and mean ages in calibrated years ka BP.
