Here we provide the updated age-depth model of sediment cores for Lake Lama (core PG1341) from arctic Siberia. The model provides the temporal information for a project on sedimentary ancient DNA shotgun sequencing (von Hippel et al., submitted). This dataset comprises the updated age-depth model for Lake Lama (Taymyr peninsula), based on the Accelerator Mass Spectrometry radiocarbon dating of 19 samples from the sediment core PG1341 (von Hippel et al., 2022) 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. An additional overlap of 145 cm was calculated between the core segments 5 and 6. This recalculation is based on the TOC data and magnetic susceptibility measured by Andreev et al. (2004). 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 ...
