Seabed Geoacoustic Structure at the Meso-Scale

Abstract

The long term science goals are to understand the nature of the seabed at geoacoustic meso-scales O(10(exp 0) 10(exp 3)) m and determine how these structures impact acoustic propagation, diffuse reverberation, and clutter. The objectives are to develop new observational methods to quantify meso-scale seabed variability/ uncertainty and also develop modeling techniques to understand the impact of spatial variability on propagation and reverberation.
