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.
