Natural explanations (Bemuda)

An explanation for some of the disappearances has focused on the presence of vast fields of methane hydrates on the continental shelves. Laboratory experiments carried out in Australia have proven that bubbles can, indeed, sink a scale model ship by decreasing the density of the water[13]; any wreckage consequently rising to the surface would be rapidly dispersed by the Gulf Stream. It has been hypothesized that periodic methane eruptions (sometimes called "mud volcanoes") may produce regions of frothy water that are no longer capable of providing adequate buoyancy for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without warning. Furthermore, clouds above the triangle have high methane concentrations due to the eruptions,[citation needed] which as experiment has shown[citation needed] can stall an airplane engine (more notably older, open engined models) in high enough concentration, caused by prolonged flight through the clouds.
A white paper was published in 1981 by the United States Geological Survey about the appearance of hydrates in the Blake Ridge area, off the southeastern United States coast.[14] However, according to a USGS web page, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.[15]
Compass variations
Compass problems are one of the cited phrases in many Triangle incidents. Some have theorized the possibility of unusual local magnetic anomalies in the area, however these have not been shown to exist. It should also be remembered that compasses have natural magnetic variations in relation to the Magnetic poles. For example, in the United States the only places where magnetic (compass) north and geographic (true) north are exactly the same are on a line running from Wisconsin to the Gulf of Mexico. Navigators have known this for centuries. But the public may not be as informed and think there is something mysterious about the compass "changing" across an area as large as the Triangle, which it naturally will.
Hurricanes
Hurricanes are extremely powerful storms which are spawned in the Atlantic near the equator, and have historically been responsible for thousands of lives lost and billions of dollars in damage. The sinking of Francisco de Bobadilla's Spanish fleet in 1502 was the first recorded instance of a destructive hurricane. In 1988, Hurricane Gilbert, one of the most powerful hurricanes in history, set back Jamaica's economy by three years.[citation needed] These storms have in the past caused a number of incidents related to the Triangle.
Gulf Stream
The Gulf Stream is an ocean current that originates in the Gulf of Mexico, and then through the Straits of Florida, into the North Atlantic. In essence, it is a river within an ocean, and like a river, it can and does carry floating objects. A small plane making a water landing or a boat having engine trouble will be carried away from its reported position by the current, as happened to the cabin cruiser Witchcraft on December 22, 1967, when it reported engine trouble near the Miami buoy marker one mile (1.6 km) from shore, but was not there when a Coast Guard cutter arrived.
Freak waves
Main article: Rogue wave (oceanography)
Extremely large waves can appear seemingly at random, even in calm seas. One such rogue wave caused the Ocean Ranger, then the world's largest offshore platform, to capsize in 1982. There is, however, no particular reason to believe rogue waves are more common in the Bermuda region, and this explanation cannot account for the loss of airplanes.
