What does SONAR mean?

SONAR is a sound propagation-based technique. It uses sound propagation to navigate, communicate or detect objects beneath or on the surface of the water. Because sound waves travel farther in water than radar and light waves, this technology is useful for exploring and mapping oceans. SONAR assists NOAA scientists in the development of nautical charts for the detection of underwater hazards to navigation, and mapping of objects on seafood such as shipwrecks.
