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 start of your premise, in which you are at the bottom of the ocean in an air pocket, is already a flawed premise. How would you get down there, by floating down with the wreckage? As the wreckage sinks, with you inside that bubble, the air pressure would increase inside, eventually causing you to implode. So forget about jumping in the water at that depth; there’s no way I can think of that you could even get in that bubble in the first place.

Someone correct me if I am wrong here.
