Abstract: We consider the propagation into shallow water of low-frequency and low-order acoustic modes trapped in the sound channel. The phase velocity slightly decreases and then increases with decreasing depth. This leads to an ...

Abstract: Explosions of 300 lbs of TNT at 1 km depth off Perth, Australia were recorded on Bermuda hydrophones, demonstrating 30 years age the feasibility of global acoustic transmissions. Climate-induced changes in ocean temperature ...

Abstract: Detonations at the depth of the sound channel axis off Perth, Australia were recorded on Bermuda hydrophones at a 178°.2 range (180° is antipodal). The analysis by Shockley et al. of this 1960 transmission experiment allows ...
