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 will be at the same pressure as the surrounding water, as everyone has pointed out. To make the problem worse, the air is compressible. The bubble will shrink proportionally with the pressure. At the bottom of the Trench, the pressure is about 1000x that of sea level. If you started with a decent sized room full of air, you’re down to about a cubic foot of air at depth.
