Abstract : Sound velocity and temperature measurements taken from the sea-surface to 350 m depth, close to one spot over a 24-hour period revealed the passage of an internal wave of approximately 60 m amplitude. The effect of this wave in breaking up a previously well-developed thermocline is demonstrated. The results of computer calculations on the effect of such a wave on the ray paths from a hypothetical sound source are presented. (Author)
