| contents | These data have been obtained from core PS2458-4 (78°10.0'N, 133°23.9'E; 983 m). The core was retrieved in 1993 from the eastern Laptev Sea continental margin. The datasets contain foraminifera radiocarbon ages. Modelled ages were calculated using OxCal4.4 (Ramsey, 2009) with a DR value of 345±60 14C years, as calculated in Nicolas et al. (2024). Marine 14C dates were calibrated with the Marine20 curve (Heaton et al., 2020). Libby half-life (5568 years) was used to calculate 14C age of foraminifera samples. |
