An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater. How deep is the water directly below the vessel if the time delay of the echo to the ocean floor and back is 6 s?

(sound speed)* (echo time) = 2 * depth

depth = (sound speed)*(echo time)/2
= 1530 m/s * 6 s * (1/2)= 4590 m
