Theory 1:
Air mixes with water makes the water less dense, hence
sucking you down.

I have seen a video where a boat was in a lab sinked by this way,

in document about the Bermuda triangle,
following the hypothesis
about sudden huge gas release
from the sea bad or underwater vulcanos.

Sinking a swimmer with density close to water
is much easier than sinking a boat.
