Abstract
Measurements of the shallow-water propagation of acoustic waves on the New Jersey continental shelf were conducted by the Naval Underwater Systems Center, September 1988. On the same site, accurate measurements of geoacoustic properties were obtained by Yamamoto et al. (1988) using the bottom shear modulus profiler (BSMP) method invented by T. Yamamoto. The bottom properties extracted by the BSMP inversion method were introduced to SAFARI computer code for modeling of normal-mode acoustic propagation by the author. Favorable agreement has been found between model calculations and results of the acoustic propagation experiment conducted by NUSC. Comparison has revealed findings about the contributions of the compressional and shear wave characteristics of the seabed to the acoustic waveguide. The compressional wave profile has been found to contribute to the characteristics of the acoustic waveguide modal structure, while the shear wave profile has been found to contribute only to the attenuation of the acoustic wave propagation.
