There is no mystery to Bermuda, on the ocean floor sometimes(keyword) gas hydrates release gas, and when too much gas is released it causes a low density in the water, thus causing ships to sink.
The phenomenon you are describing in fact happens quite often especially during seismic exploration when the shot from the ship hits a gas pocket under the surface of the sea and gas is released up. When the gas reaches the ship above it, the ship falls through it as the water density is lowered.
However, this doesn’t explain the other mysteries around the triangle, such as planes disappearing, ships disappearing and then reappearing and other weird stuff like that.
If I had to make an assumption I would say the triangle had some sort of magnetic effect that knocked out navigational equipment. But I have no idea, as I haven’t really ever looked into it all that much, but the gas pocket explanation, while valid, just doesn’t explain away the mysteries of the Bermuda triangle.
