The depth of the ocean can be measured using a device called SONAR (Sound Navigation And Ranging). Sonar works by sending out sound waves and measuring how long it takes for the echo to return. If the water is shallow, sound waves that reflect off the bottom of the ocean will return faster than in deep sea.
