Ambient Noise Measurements and Inversions in Coastal and Continental Shelf Waters

Abstract

The objective is to characterize the spatial properties of the ambient noise field in shallow water, and in particular to identify the effects that the seabed has on the spatial coherence of the noise. A full theory of the geoacoustic properties of porous materials is also being constructed, particularly in connection with marine sediments. By combining the theory of the bottom with measurements of the noise field, new inversion techniques for remotely determining the bottom geoacoustic parameters can be developed.
