Abstract
An extended series of measurements of oxygen solubility in pure water and dilutions of seawater over the temperature range 0.5 to 35C was made. Nonlinear dependence of oxygen solubility on chlorinity was found. Interpolation tables of the data have been prepared. The accuracy of the techniques was approximately 0.1%, so the tables appear to be more reliable than those in current use. Because many of the existing field data have been collected using techniques for the Winkler method that introduce significant systematic errors due to volatilization and air oxidation errors, the use of the reported solubility values with these field data will produce misleading results.
