Abstract:

These datasets describe a 31.5 m long sediment core taken from beneath thermokarst lake Goltsovoye Lake (71.74515 N, 129.30217 E) on the Bykovsky Peninsula, northeastern Siberia. The thermokarst lake was 510 cm deep. Here, we report the depths from the ice surface as well as from the sediment surface.

This dataset presents the radiocarbon ages from samples from sediment core PG2412. Calibrated and rounded calibrated ages are presented. Calibrations were performed according to Stuiver et al. (2017) using CALIB 7.1 software and the IntCal13 calibration curve.
