Spatial Statistics of Deep-Water Ambient Noise; Dispersion Relations for Sound Waves and Shear Waves
Abstract
LONG-TERM GOALS: 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 trench in the ocean at 11,000 m, the Challenger Deep in the Mariana Trench. 2) Dispersion relations for sound waves and shear waves Develop a unified, physics-based model of sound wave and shear wave propagation in saturated, unconsolidated marine sediments. New focus is on: 1) the dispersion associated with a frequency power law attenuation; 2) wave propagation in very fine-grained sediments (silt and clay).
