The depth in the ocean is measured by sounding using echo-sounders. Nowadays satellites are also used for this purpose.
Scientist use the device "Sonar."
They use an Echo Sounder. Many pulses of sound per second are sent to the ocean floor & the time it takes to rebound is measured and therefore the depth is calculated.

There are so many different depth levels of the ocean, it is pretty much impossible to calculate the average depth unless every part of the ocean is measured. Update: The average is 3,700 meters. Wikipedia gives the average depth of the World Ocean (that's taking all the Oceans as one continuous body of water) as 3,790 metres (12,430 ft),
The focal depth of an earthquake is how far beneath the earth's surface the hypo-center of the earthquake.Because of its location in the Indian Ocean, however, its focal depth is measured as 30 kilometers below mean sea level, rather than being measured at the seabed.
To convert measured depth to true vertical depth, first write down the measured depth. You will have to map an X, Y, Z point from that calculation, as well as using the azimuth and inclination.
Usually deals with hypersonic wavelengths, kinda like how bats see, and they see how long it takes to hear the signal back. Then they divide the time by 2, since the time given was the time down and back up, then they find out the speed of the hypersonic wavelength, and plug it in to the sound.
Floods are measured by a known level of depth. If the water level is over that depth, it may be considered a flood.
The average depth of the Indian ocean is I dont know honestly
Depth is a measure of distance between the surface and the ocean floor.
