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."
Ocean depth is typically measured in meters, with the average depth of the world's oceans being about 3,800 meters (12,467 feet). Depth measurements are crucial for various purposes, including navigation, marine research, and environmental monitoring. The deepest part of the ocean, the Mariana Trench, reaches approximately 10,994 meters (36,070 feet). Measurements are often taken using sonar technology and other specialized equipment.
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),
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.
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.
Ocean currents can be measured using instruments such as current meters, Acoustic Doppler Current Profilers (ADCPs), and drifting buoys. These devices can provide information on the direction, speed, and depth of ocean currents. Remote sensing technologies, such as satellites, can also be used to measure surface currents over broader areas.
The average depth of the ocean is about 2.5 miles.
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
