The Effects of Sediment Properties on Low Frequency Acoustic Propagation
Department of Ocean Engineering, University of Rhode Island Narragansett United States
Pagination or Media Count:
Our work focuses on understanding the frequency and depth dependence of compressional wave attenuation and developing new inversion schemes for shear wave properties. Our initial investigations have indicated that water-borne acoustic arrival properties such as their Airy Phase are sensitive to sediment shear properties. Our major emphasis this year has been to develop and test inversion schemes for simultaneous estimation of compressional and shear properties.
