Deep-Water Ambient Noise Profiling; Marine Sediment Acoustics; and Doppler Geo-Acoustic Spectroscopy

Abstract

Long-term goals: 1) Deep-water ambient noise profiling: Profile the spectral, temporal and spatial properties of ambient noise from the surface to the bottom of the deepest ocean trenches over a broad frequency range (3 Hz-40 kHz). 2) Marine sediment acoustics: Develop a unified, physics-based model of sound wave and shear wave propagation in saturated, unconsolidated marine sediments. 3) Doppler geo-spectroscopy: Develop the use of a light aircraft as a sound source in an inversion technique for returning the geo-acoustic parameters of the seabed in shallow water.
