Abstract:
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, biomarkers concentrations (lignin phenols; n-alkanoic acids and GDGTs), bulk organic carbon and compound-specific radiocarbon concentrations of long-chain n-alkanoic acids with 26 and 28 carbon atoms have been measured and expressed as F14C with a 1-sigma uncertainty. Furthermore, δ13C, TN, TOC and C/N values are also provided.
