VERTICAL DIRECTIONALITY OF DEEP-OCEAN NOISE,

Abstract

An experimental program utilizing a 300-foot vertical array of receivers mounted near the ocean floor in 2400 fathoms has been completed and provides information from which the vertical directionality of deep-ocean noise as a function of frequency and sea-surface condition can be inferred. Data are presented for the frequency range 112-1120 cps, based on logit band measurements, as a function of surface-wind speed and waveheight corresponding to sea-state numbers from one through six. The ability to electrically steer the array through a variety of angles of elevation provides a reasonably well-defined distribution. (Author)
