Inversion for Geoacoustic Model Parameters in Range-Dependent Shallow Water Environments

Abstract

Our ability to predict acoustic fields in shallow water is limited by knowledge of the parameters of geoacoustic models that are used to describe the interaction with the ocean bottom. The need for information about geoacoustic profiles is critical for shallow water and littoral environments where the interaction with the ocean bottom plays a dominant role in sound propagation. The long-term goal of this research is to investigate broadband matched field inversion methods for estimating geoacoustic model parameters and their uncertainties in shallow water environments that may be range dependent.
