dc.description.abstractA large set of experimental acoustic broadband data in the 50-3200 Hz band is analyzed with the objective of deriving average geoacoustic models for three sites in the Strait of Sicily. The experimental data were obtained by using explosive charges as sound sources and a vertical array of hydrophones as the receiver. CW data at 3.5 kHz is also analyzed. The acoustic data is complemented by a set of oceanographic data and bathymetry measurements. The modelldata comparison results from each site, obtained after selecting appropriate average geoacoustic models, are presented as propagation losses over range for fixed source and receiver depths. We also indicate the propagation loss models chosen for the prediction and their limits. The results demonstrate the strong effect of bottom properties on acoustic propagation in this area, the limited amount of the existing information available for model prediction, and the difficulty in automating model selection and validating model results.
