Effective Geo-Acoustic Model for Sand-Silt Bottoms in Shallow Water

Abstract

The long-term goals of this work are: to develop a practical seabed geo-acoustic model for predicting transmission loss (TL), reverberation level (RL) and signal-reverberation ratio (S/R) in shallow water with sand and silt bottoms; to characterize sea bottom geo-acoustic parameters (sound speed and attenuation) and bottom scattering strength from both sound propagation and reverberation measured in a low frequency (LF) range of 100-3000Hz, and to reveal the physics of LF sediment acoustics and bottom scattering through data analyses. The scientific objectives of this year s research include: (1) To analyze and review both sound propagation and reverberation data collected from different locations in shallow water with sand and silt bottoms. (2) To find an effective seabed geo-acoustic model to predict low-frequency sound propagation and reverberation in shallow water.
