Matched Field Tomographic Inversion for Geoacoustic Properties

Abstract

The geoacoustic properties of the ocean bottom, including sound speed profiles, densities, attenuations and sediment layer depths, have a significant effect on sound propagation in shallow water. The long term goal of this work is to investigate tomographic inversion methods based on matched field processing of broadband data for estimating geoacoustic properties over an extended region of the ocean bottom.
