Deep sound channel

• The deep sound channel is born from an experiment carried out by Maurice Ewing and J.L. Worzel in 1943

The deep sound channel is born from an experiment carried out by Maurice Ewing and J.L. Worzel in 1943 (Wertenbaker, 2000) with the premise that low frequency waves, being less vulnerable to dispersion than high ones, should be able to travel long distances without too much trouble. The experiment consisted in exploiting TNT underwater on the coast of the Bahamas, this explosion could be detected at 3,200 kilometers away and at a depth of one kilometer they found the so-called "deep sound channel" or "Sound Fixing and Ranging channel, SOFAR" (The National Academies, s.f.), on the other hand and independently, this phenomenon was discovered by Leonid Brekhovskikh (Jiménez, 2018) when studying explosions in the Sea of Japan.
