What is Echo Sounding: Depth Measurement Techniques about?

1) Echo sounding uses sound waves to measure ocean depth by timing the reflection of sound pulses off the seafloor. 2) Early methods measured the time between a sound pulse emission and its echo return, with time converted to depth using sound speed in water. 3) The British Admiralty system uses a rotating transmitter that pulses sound three times per revolution while a receiver measures the time delay between pulses, determining depth from calibrated scale readings.
