Sonar.
By using sound waves, _______ signals allow oceanographers to determine ocean depth. Sonar is a device that uses long, medium or short sound waves for navigation, communication, detection, positioning, tracking, and classification of mobile and immobile objects submerged, located on the surface of the liquid or in the air.
Sonar, which stands for Sound Navigation and Ranging, allows oceanographers to determine ocean depth by sending and receiving sound waves. The depth is calculated by measuring the time it takes for sound waves to travel to the ocean floor and back. This technique is essential for mapping the ocean floor and studying underwater environments.
