# Radiocarbon concentrations are given as fractions of the  Modern standard, D14C, and conventional radiocarbon age, following the conventions of 										
# Stuiver and Polach (Radiocarbon, v. 19, p.355, 1977).										
# Sample preparation backgrounds have been subtracted, based on measurements of 14C-free calcite.										
# All results have been corrected for isotopic fractionation according to the conventions of Stuiver and Polach (1977), with d13C values measured on										
# prepared graphite using the AMS spectrometer. These can differ from d13C of the original material, if fractionation ocurred during sample graphitization										
# or the AMS measurement, and are not shown.										
# All radiocarbon dates were calculated using the MARINE13 calibration curve (Reimer et al, 2013) with standard 400-year reservoir correction using OxCal 4.2 (Bronk Ramsey, 2009).										
# Radio carbon dates were measured at the University of California-Irvine under the supervision of John Southon.
