Abstract	Shallow water acoustic experiments were conducted by SACLANTCEN at two sites having very different oceanographic and sea-bed properties. The EnVerse '97 experiments took place near Sicily, Italy where the bottom is mostly sand and rock. The PROSIM '97 experiments were south of Elba Island, Italy where the sea-bed contains a clay layer with sound speed less than the water column overlying silt. In both experiments, the acoustic signals were transmitted from a towed source and received on a vertical array of hydrophones. These data were inverted for the geo-acoustic properties of the sea-bed, and the results are compared with standard geophysical measurements. Using identical inversion procedures, favorable results were obtained for 13 unknown geometrical and geo-acoustic parameters for both sets of experimental data.
