Diving bells have no buoyancy=- they are captive and hung from a crane or hoist structure , captive amusement-park ones have something resembling an elevator structure. Therefore if the cable(s) snap, the Bell and its complement will be lost- the air supply is piped in from the surface, they have no buoyancy- so if the lines were snapped- down you go- permanently. Contrast a submarine with ballast tanks.
It is called the surface, but the outer layer of rock beneath the land and the oceans is called the Earth's crust.

No. While there is evidence of liquid water beneath the surface there are no oceans on Mars.
The surface.
it is the rocks that found beneath the oceans
Sonar beneath the oceans.
Oceanic Crust
The oceans surface is 100% water.
The Earth's crust is made of plates which float on the Earth's mantle. They are located on the entire planetary surface. Even oceans lie on top of plates.
Under-GROUND oceans? Probably not; the current estimates for Europa indicate that the surface is probably ice, with perhaps oceans beneath the ice. If the oceans are made of water rather than some more exotic liquid, then there's at least a possibility that life might exist in that ocean.
