AMS 14C ages of sediment core LV63-41-2 ...

AMS 14C ages were measured in monospecific samples of the planktic foraminifera Neogloboquadrina pachyderma sinistral (N. pachyderma sin.) from the 125–250µm fraction, and benthic foraminifera Epistominella pacifica, and Uvigerina akitaensis from the 250–350µm fraction of the core. Five radiocarbon...

Description
Summary:AMS 14C ages were measured in monospecific samples of the planktic foraminifera Neogloboquadrina pachyderma sinistral (N. pachyderma sin.) from the 125–250µm fraction, and benthic foraminifera Epistominella pacifica, and Uvigerina akitaensis from the 250–350µm fraction of the core. Five radiocarbon measurements were performed at the Keck Carbon Cycle AMS Facility (UCIAMS) in the Earth System Science Department of the University of California, USA. Two AMS 14C datasets measured in an AMS laboratory at the Atmosphere and Ocean Research Institute, University of Tokyo (Japan). Conventional AMS 14C ages were calibrated to calendar ages using Calib 8.20 with the Marine20 calibration curve (Heaton et al., 2020) and the ΔR of 350 ± 40 years according to the reservoir age of the far NW Pacific equal to 900 years (Max et al., 2012). ...
