Moored Acoustic Buoy System (MABS): Specifications and Deployments
Abstract
The Moored Acoustic Buoy System (MABS) is a self-recording, 1700-ft long, vertical array of five hydrophones designed to measure underwater acoustic signals. The submerged, self-contained, programmable system records calibrated acoustic data that are stored on magnetic tape for analysis after recovery. MABS is capable of recording either continuously for 30 h or intermittently for up to 30 days. The calibrated acoustic signals are recorded as a function of depth in the frequency band from 3 to 5000 Hz, with a system self-noise threshold 10 dB below Knudsen Sea State 0. Analytical models and at-sea experience have demonstrated the advantages of using the anchor-last technique for MABS deployment: it provides accurate anchor placement, is a fast, uncomplicated procedure, and requires a minimum of personnel. After two trial deployments, MABS was operationally deployed in the Mediterranean Sea during the Ionian-Mediterranean Exercise (IOMEDEX) and recorded high quality calibrated ambient-noise and continuous wave (CW) signals in the band from 3 to 5000 Hz.
