Sources and characteristics of ambient noise in deep water have been the subject of extensive investigations [e.g., R. J. Urick, Principles of Underwater Sound (McGraw-Hill, New York, 1983), Chap. 7, and references therein]. More recently, fluctuations of ambient noise in shallow water has been studied by several authors [e.g., Clay et al., J. Acoust. Soc. Am. 77, 424 (1985), and references therein]. In the present work, ambient noise data from a shallow water experiment in the Pacific (water depth 600 ft; range of frequencies 50--500 Hz) are analyzed. Cumulative distribution functions and other features are examined and are contrasted with findings from the results of previous research. [Work supported by ONT.]
