Overview

Undersea acoustic applications in shallow water, to detect, communicate, navigate, monitor and measure, are dependent upon a good physical understanding of sound propagation and scattering in this highly dynamic and inhomogeneous waveguide. Achieving such an understanding requires an interdisciplinary approach encompassing acoustics, physical oceanography, marine geophysics, marine biology, ocean engineering, and signal processing, as well as the underlying physics and mathematics of the integrated theory.
