The channeling efficiency of the Deep Sound Channel (often referred as the Sofar channel) allows long range propagation of hydroacoustic waves over a few thousands of kilometers. Strong T-waves, referring to a third arrival on seismic waves, are commonly observed on underwater receivers (hydrophones...
