The Bermuda Triangle is a mythical section/loosely-defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. Most reputable sources dismiss the idea that there is any mystery. The vicinity of the Bermuda Triangle is one of the most heavily traveled shipping lanes in the world, with ships frequently crossing through it for ports in the Americas, Europe, and the Caribbean islands. Cruise ships and pleasure craft regularly sail through the region, and commercial and private aircraft routinely fly over it.
The area referred to as the Bermuda Triangle, or Devilâ€™s Triangle, covers about 500,000 square miles of ocean off the southeastern tip of Florida. When Christopher Columbus sailed through the area on his first voyage to the New World, he reported that a great flame of fire (probably a meteor) crashed into the sea one night and that a strange light appeared in the distance a few weeks later. He also wrote about erratic compass readings, perhaps because at that time a sliver of the Bermuda Triangle was one of the few places on Earth where true north and magnetic north lined up.
Nonetheless, reports of unexplained disappearances did not really capture the publicâ€™s attention until the 20th century. An especially infamous tragedy occurred in March 1918 when the USS Cyclops, a 542-foot-long Navy cargo ship with over 300 men and 10,000 tons of manganese ore onboard, sank somewhere between Barbados and the Chesapeake Bay. The Cyclops never sent out an SOS distress call despite being equipped to do so, and an extensive search found no wreckage. â€œOnly God and the sea know what happened to the great ship,â€ U.S. President Woodrow Wilson later said. In 1941 two of the Cyclopsâ€™ sister ships similarly vanished without a trace along nearly the same route.
A pattern allegedly began forming in which vessels traversing the Bermuda Triangle would either disappear or be found abandoned. Then, in December 1945, five Navy bombers carrying 14 men took off from a Fort Lauderdale, Florida, airfield in order to conduct practice bombing runs over some nearby shoals. But with his compasses apparently malfunctioning, the leader of the mission, known as Flight 19, got severely lost. All five planes flew aimlessly until they ran low on fuel and were forced to ditch at sea. That same day, a rescue plane and its 13-man crew also disappeared. After a massive weeks-long search failed to turn up any evidence, the official Navy report declared that it was â€œas if they had flown to Mars.â€ In a 2013 study, the World Wide Fund for Nature identified the world's 10 most dangerous waters for shipping, but the Bermuda Triangle was not among them. An explanation for some of the disappearances has focused on the presence of large fields of methane hydrates (a form of natural gas) 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; 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.
Publications by the USGS describe large stores of undersea hydrates worldwide, including the Blake Ridge area, off the coast of the southeastern United States. However, according to the USGS, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.
