Explanation:

SO und N avigation A nd R anging. It is an echo-sounding instrument used to measure the depth of ocean at various places. First a sound wave is sent from a ship toward the ocean floor. the sound wave is reflected off the ocean floor back to the ship. Scientists know how fast sound travels in water. So they can determine the depth of the ocean floor from the amount of time it takes for a sound wave to leave the ship in return. Computers then translate the sonar information into a map of the ocean floor.
