In a shipwreck at the bottom of the ocean containing air pockets, would you die from jumping in the water due to water pressure?

I’ve attached an image here, to further illustrate the scenario. Imagine that the wreck is at the bottom of the Marianas trench, 10km underwater.

Would jumping into the water kill you from the pressure? Or would it only kill you if you swam to where there is no cover on the right side of the wreckage?

Answer 1

The air itself in the pocket would be pressurized. If the pocket had a lower pressure than the surrounding water, the water would rush in from the bottom and compress the air pocket until an equilibrium was reached.

So no, jumping into the water wouldn’t change the pressure you feel in any way, nor would swimming outside of the wreck. The water is all around you, so just a rigid “lid” somewhere above you wouldn’t change the pressure you feel at all.
