Abstract:
The dataset presents the radiocarbon ages (with standard deviation ±) from thermokarst lake sediment cores from the Yukechi Alas, Siberia. The sediment cores were taken from an alas lake (YUK15-YU-L7) and a yedoma lake (YUK15-YU-L15). Raw, calibrated and rounded calibrated ages are presented. Measurements were carried out in the AWI MICADAS Laboratory in Bremerhaven. Calibrations were performed according to Stuiver et al. (2017) using CALIB 7.1 software and the IntCal13 calibration curve.
