Abstract : Measured values of sound velocity in sea water are compared to sound velocity calculated by several empirical relations. Among the empirical relations examined are Wilson's October, 1960 equation and Frye and Pugh's 1971 equation. Results indicate that all empirical relations have their maximum differences in the first 20 feet of sea water. The difference measured is dependent on wind induced turbulence. Of the empirical relations examined, the Frye and Pugh equation provides the most accurate results. (Author)
