Recent measurements were made in 25-f (fathom) water with 15-min CW tones of 350-, 700-, and 1300-cps sound transmitted from an anchored ship. The sound was received on an anchored vertical string of 14 hydrophones spaced 10 ft apart. The measurements were made to a range of 80 kyd over selected paths for which the thickness of the subbottom had been previously surveyed acoustically. The mean signal level at each hydrophone can be determined with an estimated accuracy of 1 dB. These mean levels define the CW sound field accurately for the first time. They exhibit a definite significant dependence on hydrophone depth as could be expected from the normal-mode theory. The signal-level fluctuations and frequency spreading agreed with earlier measurements [J. Acoust. Soc. Am. 34, 67 (1962)]. The sound levels averaged from the surface to the bottom agree with the ray theory [J. Acoust. Soc. Am. 33, 1505 (1961)].
