Geoacoustic Parameters of Marine Sediments: Theory and Experiment

Abstract

There are two long term goals, as follows. 1) Sediment Acoustics Develop a physics-based model to characterize the inter-relationships that exist between the geo-acoustic properties (i.e., compressional-wave speed and attenuation, shear-wave speed and attenuation, frequency, density, porosity, grain size, grain shape and overburden pressure) of saturated, unconsolidated granular media such as marine sediments. 2) Deep Water Ambient Noise Profiling Depth-profile the spatial and temporal properties of ambient noise from the sea surface to the greatest depths of the ocean over a broad frequency band (10 Hz - 100 kHz).
