The Systems Engineering Staff of the NRL Acoustic Division has the requirement to build a long-term, unattended, bottom-anchored buoy for collecting acoustic ambient noise in the deep ocean. With a nucleus of surplus equipment from two buoy projects of the 1960s plus additional equipment designed and built at NRL, seven Ambient Noise Buoys were fabricated. One was designed for investigation in the frequency range of 1 to 10 Hz with four hydrophones, three were designed for the band from 20 to 400 Hz with two hydrophones, and three were designed for the band from 20 to 400 Hz with one hydrophone.
