Abstract :
The author reports a study of the functional variations between acoustic bottom loss from 50-1500 Hz and the sediment geoacoustic parameters of density, sound speed, thickness and attenuation. She shows simple relationships between certain of these parameters and specific angular regions of the loss curves. These relationships permit bottom losses to be estimated directly from the geoacoustic parameters without the need to exercise complex layer modeling
