Abstract:

A broad geoacoustic assessment of three regional shallow-water areas has been made. The geoacoustic properties within each region are mapped into three geoacoustic models representing low sand-sift-clay, moderate clayey- sift and high silty-clay bottom loss. Representative extreme sound speed profiles are used to generate a cone of launch angles where the loss is less than a specified amount per bounce. In general, only regions of low loss have good propagation characteristics for each extreme of sound speed.
