Abstract:

NORDA has established an environmental acoustics program that focuses on the relationships between ocean bottom physical properties and acoustic scattering. The program is designed to make environmentally supported acoustic scattering measurements in areas that range from simple and uniform to those that are more complex. With careful site selection it should be possible to correlate changes in ocean bottom physical properties with changes in acoustic scattering strength, correlation and coherence estimates. Keywords Acoustics Reverberation Frequency, Shallow water.
