I found a series of translucent boxy outlines that appear to be an unfinished building on the ocean floor of a Minecraft Map Seed.
I went to checkout the structures and fell right through them. Then was unable to swim back through them to reach the surface again. I wound-up digging a trench underneath, sealing it with dirt blocks to recover my character's oxygen. Then getting back to the surface by digging a tunnel a short distance away from the boxy structures.
The screen grabs included show the structures I'm referring to and the "chunk base" picture shows the Minecraft Bedrock Seed Number along with the coordinates to locate the structures.

On looking closer, based on the grassy patches and elemental properties. The boxy structures are most likely air pockets in a section of the map that was supposed to generate above water.
That would also explain why my character couldn’t swim back through them to reach the surface.

I cannot reproduce this. The seed generates a normal ocean (or maybe deep ocean) and ocean floor at the given coordinates.
The air pockets and grass generation can occur after pruning a world with a 3rd-party app, but that would not be a valid issue for the bug tracker.
No 3rd party app was used or any other app modification. These air pocket and grass structures under water were discovered in the official Minecraft PE iOS edition on survival mode.
