Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !

How the depth of the sea determined by sound waves?
sonar
What are the applications for sonar?
A)to find the depth of the sea b)the sonar device measures the time taken by the ultrasonic sound to travel from the ship to the bottom of the sea .
How is sea beam used?
It maps ocean-floor features, sea beam relies on sonar which is the use of sound waves to detect & measure objects underwater.
What is an application of sonar?
it s used in sea ...... by giving sound from d ship it travel to deepth of d sea and reflect back so it s used to give signals...
How does the density of water change with depth?
the density of sea increases with depth

Sonar measures underwater distances by using what?
Using the speed of sound in water (about 1500m/s in the sea, depending on the specific sea-water density). So if there is a delay of 2 seconds between a depth-sounding sonar emitting a pulse and detecting its echo from the sea-bed, the water is 1500 X 2 = 3000m deep.
What do Scientsts use sonar for?
Scientsts use sonar to map the depth of water in sea and river etc..,they also use sonar to locate and identify object underwater
What types of technology are used to study ocean floor?
Its FathometerUsing SONAR (Sound Navigation And Ranging) we can measure the depth of the sea.FathometerSONARSONAR: An acronym for SOund Navigation And Ranging.Sonar is used.usually "sonar" is used for its measurementbuutttSonogram
How does the information gathered by ships using sea beam sonar differ from the collected with standard methods that use one sonar device?
A sonar uses one device and a sea beam uses a dozen sonar devices.
How does the information gathered by ships using Sea Beam sonar differ from that collected with standard methods that use one sonar device?
A sonar uses one device and a sea beam uses a dozen sonar devices.
What is the instrument used to measure the depth of sea called?
The simplest and older - shot-line. For faster and more accurate work, especially in deep water, sonar is used now; its simplest form being the echo-sounder.
What have people specifically found with sonar?
Sonar is a way of finding things underwater, using the echo of sounds you emit. We have used it to find the shape of the lake/sea/ocean bottoms, to determine the depth of waters, to find fish, to locate ship wrecks, and to detect the presence of ships and especially submarines.
Do they measure river depth by sea level on some rivers?

What cartographers use to measure the height and depth of earths other features?
Sea level
