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

Neither of your options is correct.

Remember that the water isn’t flowing into the air pocket because the air is pushing back just as hard as the water. All the water at that depth is under the same pressure, as otherwise there would be a flow from the higher pressure area to the lower.

So the air the person is in must be the same pressure as the water at that depth. Stepping into the water would have zero change in pressure on their body.
