DOWNLOAD EBOOKReceived time series from explosive sources in an abyssal plains ocean environment are compared to simulated time series calculated by a ray theory model. The comparisons yield information concerning the geoacoustic profile with a single sediment layer. The comparisons are made in various frequency bands to aid in identifying sediment penetrating arrivals by taking advantage of the frequency dependence of the absorption of the sediment. For shorter ranges, the sediment penetrating rays reflect off the basement. Also, as the range decreases, the fraction of received energy due to reflections at the water-sediment interface increases. Discrepancies between the experimental and simulated time series are interpreted in terms of reflections from thin layers within the sediment and scattered basement reflections
