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.
