Deep Water Acoustic Arrays

Abstract

Proposed is the fabrication of two, 1000 m~aperture, 32-element, deep water acoustic array systems capable of receiving in the 20 H"z to 40 kHz frequency band (although their predominant use likely will be for low/mid-frequency data collection). These arrays will complement two deep water acoustic arrays previously fabricated under prior DURIP support and will take advantage of existing data acquisition systems that have been used successfully in a number of shallow water array experiments. Added here will be the 1000 m~aperture, 32-element array harnesses, deep-water pressure cases for the dataacquisition electronics and battery packs along with protective cages placed mid-array for mounting the data acquisition systems and related hardware, and mooring hardware including deep water acoustic releases and buoyancy. The deep water arrays will add an important new capability for the collection of low/mid-freq"uency ambient noise, propagation, and acoustic communications data.
