Concept explainers
To explain: The method of measurement of the depth of seawater to be taken by crew members in a ship.
Explanation of Solution
Introduction:
To measure the depth of the sea, a device called echo sounder is used. The depth is determined by measuring the time taken by a sonic pulse to reach the bottom of the water body and return to the surface.
An echo sounder is a form of sonar used by transmitting sound waves into the water to determine the depth of the sea. The time interval between sound release and return is determined, and the distance is determined with respect to sound velocity in water. Echo sounders can use different sound frequencies to find out various things about the ocean.
Conclusion:
Hence, the crew members can measure the depth of water in the sea using an echo sounder.
