Acoustical Properties of Mud Sediments
Abstract
Funding will be used to carry out an investigation with a goal to develop analytical models that explain observed acoustic properties and predict such properties for mud sediments in shallow oceanic waters. Specifically, with work seeks to (1) Develop a theoretical and quantitative model for the interaction of mineral platelets in mud sediments; (2) Develop analytical models that explain the observed attenuation of acoustic waves in mud sediments; (3) Develop analytical models that explain the depth-dependence of material and acoustic properties, including the material density and the frequency-dependence of wave speeds and attenuation; (4) Use the developed theory to provide a basis and methodologies for inverse methods for determination of specific parameters and profiles associated with mud sediments at the bottom of the ocean; (5) Develop a quantitative theory for predicting the circumstances under which bubbles will be present in mud samples; (6) Develop a quantitative theory for the shapes, orientation, and size distributions of bubbles in mud; (7) Develop a quantitative assessment of the effects of bubbles in mud on the acoustic detection and classification of objects buried in mud.
