Comment:
Radiocarbon dating of micro-inclusions of organic material extracted directly from massive ice samples was carried out at the Laboratory of Radiocarbon Dating and Electron Microscopy of the Geography Institute of the Russian Academy of Sciences and the Center for Applied Isotope Studies, University of Georgia (USA) on the 500 kV NEC 1.5SDH-1 Pelletron (CAMS).14C ages are reported in 14C years before present (BP) following international conventions (Stuiver and Polach 1977; Millard 2014). Calibrated ages in calendar years were obtained using OxCal v 4.4.4 (Bronk Ramsey 2021) and the IntCal20 calibration curve (Reimer et al. 2020, doi: 10.1017/RDC.2020.41).
