Theorists have long suspected that methane coming from the bottom of the ocean in the Bermuda Triangle might have something to do with the disappearance of many a ship and plane over the years. Now new research in the Barents Sea off Norway provides even more insight into why methane may really be related to the many mysteries in the Bermuda Triangle.

“Multiple giant craters exist on the sea floor in an area in the west-central Barents sea and are probably a cause of enormous blowouts of gas,” researchers from the Arctic University of Norway told The Sunday Times. “The crater area is likely to represent one of the largest hotspots for shallow marine methane release in the Arctic.”

The massive craters reportedly measure 150 feet deep and span up to a half a mile wide, according to The Sunday Times, and harbor massive supplies of collected methane gas that eventually bubble their way to the surface. These might cause issues for ships traveling by, which are suddenly trapped in a bubbling ocean or, worse, explosions of methane that suddenly hit the surface.

A Russian scientist quoted by The Daily Mail suggested the large collections of methane could cause the “ocean to heat up and ships [to] sink in its waters mixed with a huge proportion of gas.”

The report doesn’t explain why planes would go missing in the same area… so maybe there’s still some mystery to the Bermuda Triangle after all.
