    Echo Sounder - Principle, Working Errors

    PrincipleWorkingErrors of The Echo SounderWhat Are An Echo Graph and Echometer?It s on the principle of transmitting sound waves from ship’s bottom and then measuring the time taken for the echo to be returned from sea. If the velocity of sound in water is known the time will be proportional to the distance travelled.The time taken by the waves to travel to and from the seabed is measured and depth can be determined, by the formula Distance=Velocity x Time/2在cultofsea上查看更多信息

    Fisheries acoustics - Wikipedia

    Basic Theory. Biomass estimation is a method of detecting and quantifying fish and other marine organisms using sonar technology. An acoustic transducer emits a brief, focused pulse of sound into the water. If the sound encounters objects that are of different density than the surrounding medium, such as fish, they reflect some sound back toward the source.
