ocean depth

How far down

Ocean depth is the vertical distance from the sea surface to the ocean floor.

The term appears in scientific and navigational contexts: The ocean depth here exceeds three miles.

It also serves as a measure of mystery or unknowability—the deep ocean remains less explored than the moon's surface.
