The ranges of Delta C-14 measurements for each cruise (11-30 parts per thousand) were larger than the total uncertainty (7.8 parts per thousand, 2-sigma) of the measurements. The variability is attributed to changes in the upper water mass that took place at each site over a two to four week period. These results indicate that variability of surface Delta C-14 values is larger than the analytical precision, because of patchiness that exists in the DIC Delta C-14 signature of the surface ocean. This additional variability can affect estimates of geochemical parameters such as the air-sea CO2 exchange rate using radiocarbon. (C) 2008 Elsevier B.V.
