locate survivors at sea

Sofar was developed to locate survivors at sea.

Explanation:

SOFAR (SOund Fixing And Ranging transmission) is a technique that allows sound to travel great distances. It was developed during World War II to find survivors at sea.

The ocean can be considered as a particular region having different layers due to the differences in the salt content and temperature variations. When a low-frequency sound is emitted from a certain depth in the ocean, it bounces between these layers. This causes the bending of sound waves and allows the sound to travel great distances without significant loss in the signal energy. The other applications of SOFAR include the measurement of ocean temperatures and currents, detection of the movement of submarines, etc.

Explanation:

"Sofar" (sound fixing and ranging) was developed in World War II to aid in the location of survivors at sea.
