How do we measure the depth of the ocean?

Depth finder. Depth finder, also called echo sounder, device used on ships to determine the depth of water by measuring the time it takes a sound (sonic pulse) produced just below the water surface to return, or echo, from the bottom of the body of water.Click to see full answer. Likewise, people ask, how do you measure the depth of the ocean?The depth of the ocean is calculated by knowing how fast sound travels in the water (approximately 1,500 meters per second). This method of seafloor mapping is called echosounding. Echosounders can use different frequencies of sound to find out different things about the ocean.Beside above, how do you measure depth? The length of a side from bottom to top is height. The length of a side from left to right is breadth, or width. The length from front to back is depth, but depth can also be the length from top to bottom. The length from one corner to the opposite corner is just the length of the diagonal, no special words for that. Then, which device is used to measure sea depth? SOnar What is Fathometer used to measure?Fathometer is used to measure Ocean depth. Fathometer is A depth finder that uses sound waves to determine the depth of water. The Richter Scale is used to measure the intensity of Earthquakes.
