SOFAR channel

SOFAR channel(sound channel) An acronym for the SOund Fixing And Ranging channel, a zone in the oceanic water column at a depth of about 1500 m, where the velocity of sound is at a minimum value. Sound passing through the zone is refracted upwards or downwards back into the zone, with little loss of energy, causing sound energy to be trapped in a zone of well-defined depth. The SOFAR channel may be used for the transmission of sound over long distances, exceeding 28 000 km, and can be used to track free-drifting, subsurface, neutrally buoyant floats.
