Remote Sensing of Acoustic Properties of Shallow Water Sediments: A review
Abstract
A review is presented of remote sensing methods and associated inverse procedures for obtaining the acoustic properties of sediments in shallow water. The properties of interest are the vertical profiles of density, compressional wave velocity and attenuation, and shear wave velocity and attenuation. For compressional waves, the remotely sensed information required is the modal reflection coefficient of the seabed, usually expressed in terms of the depth-dependent Green's function at specific locations in the water column. For shear waves, information about the Scholte and Rayleigh interface waves on the seabed is necessary. Also reviewed are methods for remote sensing of the Biot geophysical parameters, shear modulus, permeability, and porosity, from which geoacoustic properties can be derived.
