Abstract
A physical sediment model based on Biot Theory as modified by Stoll is used to predict the geoacoustic properties of the sea floor. The sediment properties are predicted as functions of depth and frequency for use as inputs to acoustic simulation models. The geoacoustic predictions are compared with geoacoustic descriptions derived from inversion of acoustic bottom loss data. The acoustic significance of observed differences is assessed using acoustic simulations such as bottom loss and propagation loss. The sensitivity of geoacoustic predictions to the variability of sea floor geophysical properties is discussed. [Work supported by ONR and NORDA.]
