A COMPARISON OF BROADBAND AND NARROW-BAND MODAL INVERSIONS FOR BOTTOM GEOACOUSTIC PROPERTIES AT A SITE NEAR CORPUS CHRISTI, TEXAS

Detailed comparison between narrow-band and broadband techniques used in a series of acoustic experiments are presented with emphasis on (a) comparisons of the pressure field versus range predicted, (b) comparisons of the bottom compressional-wave-speed model generated, (c) the variance of the bottom model estimated, and (d) the resolution of the bottom model generated. The range dependence of the bottom medium and the seasonal dependence of the near-surface sediment sound-speed profile are observed and discussed
