Abstract
Spatial variability of seabed geoacoustic properties generates uncertainty in the prediction of sonar system performance in littoral regions. In order to investigate geoacoustic variability within a region and variability between two regions, extensive geoacoustic and acoustic measurements were conducted in two areas in the Italian littoral. While it is not surprising that significant geoacoustic and acoustic variability is observed in each region, the surprising result is the marked similarity between the two regions. Geoacoustic properties were quite consistent when compared at commensurate water depths even with inter-region separation in excess of 800 km. Not only was the variability comparable between the two regions, but the geoacoustic regimes themselves were similar. The similarities have important implications for extrapolation of sparse geoacoustic data.
