Shallow-Water Mud Acoustics
Abstract
The first goal of this proposal is to develop methods that explain observed geoacoustic properties of shallow water mud sediments and to apply the methods to different types of muds. Properties include porosity and compressional and shear sound speed and attenuation, particularly depth and frequency dependence. Bubbles are important constituents of mud, so an additional goal is the characterization and prediction of bubble properties. Evaluation of the required accuracy of mud parameters for forward and inverse acoustic problems is a third goal. This work represents continuation of research in Area C (“Upper Sediment Layer Effects”) of ONR Grant N000141310095 (“Shallow-Water Acoustics”) to Rensselaer, which expires 31 Dec 2014. The research will be carried out in coordination with Dr. Allan D. Pierce, who is supported by another ONR grant (“Acoustical Properties of Mud Sediments”).
