Influence of Semiconsolidated Sediments on Sound Propagation in a Coastal Region

摘要: In 1976, acoustic measurements were performed in shallow water off the coast of Jacksonville, Florida. Seismic refraction and Stonely wave experiments, as part measurement program, revealed that seabed at site consisted a semiconsolidated sediment overlain by thin layer sand. Compressional shear velocities determined for 2400 m/sec 670 m/sec, respectively. Using normal-mode model includes effects rigidity, attenuation first normal mode was computed compared with experimental results frequencies 40 Hz to 800 Hz.
