Multibeam and Sonar
Sonar- Sonar stands for Sound Navigation and Ranging. It is used to determine water depths as well as locating and identifying underwater objects.
Transducer- An acoustic signal or pulse is transmitted into the water by underwater speakers. It may be towed in a container called a towfish or it could be mounted on the hull of a ship.
The sonar is also capable of calculating the distance of an object by having the sound bounce off the object and returns an echo to the sonar transducer. The time elapsed between the emission of the sound pulse and the reception of the echo. The multibeam data can be used to create three-dimensional models and even fly-by videos that simulate a trip across the area being mapped.
