AN APPRATUS calld sonar is used to locate underwater objects and to find the depth of water.it sends out high freqncy sound viberations called ultasonic viberations,into the water.the time taken by the viberations to return is then used to calculatethe distance of the reflecting surface.
Sonar determines ocean depth by measuring the time it takes for sound waves to travel from the surface to the ocean floor and back. It also relies on the speed of sound in water, which is approximately 1,500 meters per second. By calculating the time delay and knowing the speed of sound, sonar can accurately calculate the depth of the water.

SONAR
Scientist use the device "Sonar."
To find out the ocean`s depth
A device called a echo sounder or sonar is used to measure the depth of the ocean using sound waves. Sound waves are emitted from the instrument and the time taken for the sound waves to bounce back from the ocean floor is used to calculate the depth.
Sonar.
sound waves can penetrate the ocean floor.
Scientists use echo sounders or sonar technology to measure ocean depth. These tools work by sending sound waves down into the water and measuring how long it takes for the sound to bounce back, allowing scientists to calculate the depth of the ocean floor.

Unfortunately the ship sank
To map ocean depth using sonar, two key pieces of information needed are the time it takes for the sound waves to travel from the sonar device to the seafloor and back (ping time), and the speed of sound in water at different depths. By calculating the distance based on ping time and speed of sound, the ocean depth can be accurately mapped.
