Geoacoustic Inversion Using Vertical Line Array Data

Abstract

The long-term goal of this work is to develop a method to extract depth-dependent normal modes and to invert for the acoustic parameters of the ocean and ocean bottom using acoustic data measured on a vertical line array. Funding from this grant was also used to improve, maintain, and distribute a state-of-the-art acoustic normal mode model. The objectives of the FY00 work were to apply the mode extraction and geoacoustic inversion techniques developed in previous years under ONR funding to measured data and evaluate the strengths and limitations of the methods.
