Remote Seabed Sediment Classification and Sediment Property Estimation Using High Resolution Reflection Profiles

Abstract

The long-term goal of this program is to develop normal incidence FM acoustic reflection techniques for remotely measuring the physical and acoustic properties of ocean sediments and to improve our understanding of seabed acoustics. (1) Develop signal processing techniques for inverting normal incidence acoustic data to calculate vertical profiles of acoustic and physical properties such as acoustic impedance, compressional wave attenuation, bulk density, mean grain size, etc. (2) Determine interrelationships between directly measured acoustic properties and other acoustic and physical properties such as sound velocity, shear strength, grain size, porosity, gas concentration. (3) Develop acoustic models of sound interacting with the seafloor to provide a theoretical basis for signal processing techniques and property interrelationships.
