A Large-Aperture Acoustic Array to Observe Oceanic Density Structure

Abstract

A large aperture, planar hydrophone array, with sound source, has been constructed and operated by the Marine Physical Laboratory. The Scattering Array (SCAR) is being used as a remote sensing device to observe the density distribution in the oceanic water column. The array of 128 elements is towed to sea, submerged and suspended from a surface vessel. Real-time digital array phasing will allow discrimination between specular reflection (density layering) and point scatterers (biota).
