High precision measurements of the solubility of carbon tetrachloride (CCl4) in pure water and seawater were made over the temperature range of ~0-40°C. For comparison with previously reported results, the solubilities of CFC-11 and CFC-12 were also measured during these experiments. The experimental data were fit to equations in temperature and salinity, in the form used in previous gas solubility studies. The CFC-11 and CFC-12 results were generally in good agreement with earlier work, although some differences were noted. For CCl4, the standard error of the measurements from the fitted curves was ±2.5%. The concentrations of dissolved CCl4 measured in near-surface waters on a recent long meridional section in the South Pacific Ocean (where the temperature ranged from -1 to 29°C) are compared to calculated saturation levels based on these solubility data and atmospheric levels of CCl4 measured along the section.
