Geoacoustic Inversion and the Evaluation of Model and Parameter Uncertainties

Abstract

LONG-TERM GOALS: The development of new geoacoustic inversion methods, their use in the analysis of shallow water experimental data, and evaluation of geoacoustic model and parameter uncertainties including the mapping of these uncertainties through to system performance uncertainties. OBJECTIVES: The development of new geoacoustic inversion procedures for use into the kHz frequency regime, the development of methods for estimating the entire posteriori probability densities of the geoacoustic parameters being investigated along with the mapping of these parameter uncertainties through to characterizations of applied interest (e.g. transmission loss), and the demonstration of their use in the analysis of data collected during the Shallow Water 2006 (SW06) experiment.
