Measurements of surface reverberation made in the North East Pacific are presented. Sounds produced by 1‐lb explosive charges detonated at depths between 175 and 1000 ft yielded scattering strength results in the frequency range 320–10 240 cps, and between grazing angles of 2° and 75°. The scattering‐strength values are generally lower than those reported in the literature. Although the range of wind speeds over which the data were gathered was not great, a wind‐speed dependence is indicated, as is a frequency dependence. A program of surface‐wave measurement in conjunction with surface‐reverberation measurement has been initiated in an effort to resolve the variation in the results obtained by different investigators.
