Underwater Sound Transmission Through the Ocean Floor

摘要: Predictions of sound transmission in the deep ocean ordinarily rely on ray diagrams and trace calculations, wherein floor is assumed to be an impenetrable boundary that does nothing more than reflect back up into sea. Yet, there a growing body experimental evidence indicate refracted traveling through makes significant contribution This includes recent work with geophone as sensor underwater sound, measurement continental slope, some findings low-frequency, low-angle bottom loss.
