Spatial Statistics of Deep-Water Ambient Noise; Dispersion Relations for Sound Waves and Shear Waves

Abstract

Long-term goals include: 1) Deep-water ambient noise Profile the spectral, temporal and spatial properties of broadband (3 Hz 30 kHz) ambient noise from the sea surface to the seabed in the deep ocean trenches. Develop theoretical models of the second-order spatial statistics of the noise. New focus is on the deepest part of the ocean, the Challenger Deep in the Mariana Trench. 2) Marine sediment acoustics Develop a unified, physics-based model of sound wave and shear wave propagation in saturated, unconsolidated marine sediments. New focus is on very finegrained sediments (silt and clay).
