Probabilistic Geoacoustic Inversion in Complex Environments
Abstract
This proposal aims to develop new inversion methods for complex ocean environments for a range of geoacoustic data types. The focus is on (1) improving automated param- eterizations to capture seabed variability and uncertainties consistent with data reso- lution, and (2) improved numerical methods for parameter and uncertainty estimation for greater reliability and e ciency (computational cost is currently a limiting factor in uncertainty estimation). These improvements will expand our ability to apply inver- sion to problems of increasing complexity while reducing the subjective assumptions made in the quantitative inversion. Fundamental advancements in inversion/inference methods are required since science goals of the ocean acoustics community are increas- ingly focused on more complex environments and/or more complex wave propagation theories. The methods will be developed with simulated data and measured data (ex- isting and new). In particular, data from the Ocean Acoustics Seabed Characterization Experiment will be considered once available.
