14C dates of organic remains in ice wedges and enclosing sediments of Seyakha yedoma in the north of Western Siberia

14C dates of organic remains in ice wedges and enclosing sediments (central part of Seyakha yedoma exposure). Calibrated using OxCal 4.4 equipped with IntCal 20 (Reimer et al. 2020, doi:10.1017/RDC.2020.41). The isotope dates of water and ice samples were obtained at the isotope laboratory of the Department of Geography, Moscow State University, using a Delta-V mass spectrometer with a standard gas-bench option. For measurements we used the V-SMOW, GISP, and SLAP international standards, and the standards of the laboratory.
