Abstract
During a recent shallow water experiment, acoustic propagation of a continuous 400 Hz signal was measured over a 18.5-km range, from a fixed source to a broadside array of hydrophones. Transmission loss varied significantly over a wide range of time scales during certain periods, and was relatively uniform during other periods. During intermittent intervals, acoustic features appeared to propagate across the array of hydrophones, at a speed of about 0.75–1.0 m/sec. This speed is similar to the propagation speed of internal soliton waves, as predicted by internal wave theory.
