The Menlo Park Radiocarbon Laboratory utilizes gas proportional counting of carbon dioxide in counters installed 9.5m below the ground surface for background reduction (Robinson, 1977, 1979; Robinson & Trimble, 1981, 1983). The reported results of geologic samples closely follow the guidelines of Stuiver and Polach (1977). The standard errors for analyses earlier than USGS-500 are based solely upon counting statistics, while later analyses include estimates of uncertainty in voltage, pressure, temperature, and δ13C. Unless otherwise noted, organic samples are pretreated in NaOH and HCl, and carbonate samples in HCl.
