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 average depth of the world's oceans is about 12,080 feet (3,682 meters).
The depth and the vastness of the oceans.
2930 meters
The average depth of the Southern Ocean is around 13,100 feet (3,990 meters). This makes it one of the deepest oceans in the world, with significant variations in depth across its vast expanse.
One modern technique used to measure the depth of oceans is bathymetry, which utilizes sonar technology to send sound waves to the ocean floor and measures the time it takes for the signals to bounce back. This data is used to create detailed maps of the ocean floor topography.
in ten years the average depth of the ocean will be 2 feet. Right now it is 10 hundred feet
2. Pacific By far. The Pacific is the deepest (and largest ocean) on Earth - average depth: 4,280 metres (14,000 feet). By contrast, the Arctic's average depth is 1,038 metres (3,410 feet), less than 1/4 of the Pacific Ocean's average depth.
Oceanic crust is roughly 4 miles in average depth. Continental crust is on average 25-30 miles in depth.
The maximum depth of oceans is 10,923 meters/6,787 mi.

im not sure
The depth of water at the apex of the ridge is less than 2,700 metres.
