Geoacoustic Inversion for Spatially and Temporally Varying Shallow Water Environments

Abstract

The long-term objective of this work is to develop methods for rapid assessment of seabed variability combined with detailed localized geoacoustic inversions to characterize the bottom for shallow-water environments. Consideration is given to spatial and temporal variability of water column properties common to shallow-water environments and their impact on inversion results. Methods will be developed in recognition of Navy needs for Rapid Environmental Assessment (REA) in littoral regions and corresponding interests in Intelligence, Surveillance, and Reconnaissance (ISR), Anti-Submarine Warfare (ASW), and Mine Warfare (MIW).
