The ages are initially presented in conventional radiocarbon years (5730 a half-life), corrected for isotopic fractionation, and without reservoir correction. Samples with d13C values shown as 0 per mil produced insufficient CO2 to prepare an aliquot for 13C determination. The d13C value of 0 is assumed for these samples. An error in d13C of 1 per mil corresponds to an error of 8 radiocarbon years. The calibrated 14C ages (an approximate calendar timescale, pre-1950 AD) were calculated using the relationships provided by Stuiver and Reimer (1993), for samples with conventional ages less than 10 ka; and using Bard et al. (1998), for samples older than 10ka. For marine samples a reservoir correction of 400 years has been applied. No reservoir correction is applied for lacustrine samples (OZE 254, 259, 250, 251, 252, 253) because of the current absence of information concerninglacustrine 14C reservoir values for Lake Carpentaria.
