Geography. Where is the Bermuda Triangle?

Bermuda Triangle is located between Bermuda Island on the west side of the Atlantic Ocean, straits of florida and Puerto Rico Island at the eastern end of the Greater Antilles. Most of them are located between 20 and 30 north latitude and belong to the north tropics. It is mainly controlled by tropical air mass throughout the year, and the northeast trade wind prevails.

There are many tropical hurricanes in summer and autumn, and the wind roars, often forming a water wall with a height of more than 10 meters, and you can often encounter tornadoes at sea, which can suck seawater to a height of several thousand meters and cast a terrible shadow on the beacon cover.

Moreover, the Bermuda Triangle is located on the northern edge of the crustal fault zone between North and South America, where volcanic and seismic activities are very strong and the seabed topography is very complicated. Below the Bermuda Triangle, most of them are North Asian-American basins with a depth of less than 6000 meters;

In the north, it is the Bermuda Plateau protruding from the Sichali Basin; in the west and southwest, it is a vast continental shelf close to the mainland and islands; in the south, it is the Puerto Rico Trench with a depth of 9215m.

In addition, there are obviously prominent peninsulas such as Florida Peninsula and Yucatan Peninsula near the Bermuda Triangle, and the relatively closed Gulf of Mexico surrounded by peninsulas. There are many islands and straits: Bahamas, Greater Antilles and Lesser Antilles, 1200 islands.

These islands face the vast Atlantic Ocean, shielding the Caribbean Sea and greatly increasing the complexity of ocean currents. The Atlantic North Equatorial Warm Current turns northwest near the Antilles and crosses the Bermuda Triangle.

In addition, the Florida current flowing from the Gulf of Mexico through the straits of florida is very strong, with a width of 150km, a depth of 800m and a daily velocity of 130 ~ 150km. Such a "mighty army" also crossed the Bermuda Triangle.

The ocean currents in Bermuda Triangle are complex, strong and fast, and the wrecked planes and ships will be swept away by the powerful ocean currents even if they don't sink to the bottom of the sea. Bermuda Triangle is a part of the sargasso sea, and the sea surface is covered with brown algae, mainly Sargassum, which is not conducive to navigation.

Different writers have different views on the specific location of Bermuda Triangle, and the area of Bermuda Triangle also changes with different works.

Extended data:

Research and exploration:

Species survey:

According to the Daily Telegraph, in April 2006, 28 oceanographers from 14 countries made a 20-day expedition in the Bermuda Triangle, and captured all plankton living at a depth of 4.8km from the sea surface to the seabed.

Among thousands of captured organisms, scientists have classified 500 species and analyzed the gene sequences of more than 220 species. The results showed that at least 20 species of plankton were discovered for the first time. In addition, scientists have discovered 120 kinds of fish, several of which are also "specialties" of Bermuda.

This expedition is part of the global "Census of Marine Life" project. "We are mapping the distribution of marine plankton, just like astronomers map stars in space," said Dr. Peter Webb of the Woods Hole Institute of Marine Geography, who is in charge of the survey.

At present, there are 7,000 known species of plankton in the world, and the number may double by 20 10. Scientists hope to record all plankton and reveal their role in the earth's climate and marine food chain.

According to a rough estimate, every 1000 pound of phytoplankton can feed 1000 pound of small zooplankton, while small zooplankton can provide food for 100 pound of large zooplankton, and they can feed 10 pound of small fish. Finally, this small fish of 10 kg will become the dish of 1 kg big fish.

Plankton is not only the most basic food source for marine fish, but also helps to purify the atmosphere. The ocean can absorb carbon in the air, largely because of the activities of plankton.

Abnormal tape:

The Bermuda Triangle is unique in its ocean and atmosphere. The wave band emitted by the ocean and atmosphere here is different from other ocean areas. As a result, many ships and planes disappeared here. The data recorded by satellite shows that there is a geomagnetic anomaly zone in the South Atlantic, where only the internal radiation of the Earth exists. This radiation belt is named Van Allen Belt.

The radiation of the earth has two kinds: external radiation and internal radiation. They reach the magnetosphere and accumulate high-energy particles, thus preventing them from invading the earth. The inner band is mainly composed of protons, while the outer band is full of electrons.

The inner and outer rings are doughnut-shaped. James Fan, an American scientist, discovered this inner band after analyzing the data returned by the Explorer 1 satellite. Therefore, the Bermuda Triangle Radiation Belt is named Van Allen Belt.

This also proves the research of former Soviet physicists Sergei Vilanov and Alexander. Scientists say that it is because there are tapes in the Bermuda Triangle that this rare geographical situation has arisen. They collected data through the Russian spacecraft 3.

Data show that when there are long-term solar activities, such as flares and sunspots, the earth sometimes changes and a third band appears. When the sun is stable, this band will naturally disappear.

In 20 12, NASA launched two measuring satellites. Through their measurements, the data obtained show that particles in this area can accelerate from zero to near the speed of light in an instant, and in addition, they will emit ultra-low-speed electromagnetic waves.

Italians use some unclaimed satellites to collect data. They launched a satellite called BeppoSAX. The satellite operated from 1996 to 2003. When the satellite passed over the Bermuda Triangle, it obviously felt the radiation increase, and when it flew away from Bermuda, the radiation gradually disappeared.

Submarine pyramid:

1967, American pilot Roibert Briuis and his assistant Dimitri le Pikov flew at low altitude in Bahaba Islands of Bermuda. Suddenly, they found a huge rectangular object under the surface of Bimini Island.

In August of the following year, the investigation team came to the waters of Bimini Island to carry out underwater archaeological work, and found that there were huge stone buildings lying on the ocean floor under Bimini Island, with compact structure, large scale and diverse shapes.

The large stone wall with a length of 1.600 meters is made of large stones with a length of 4.5 meters, a width of 6 meters and a height of 3 meters, and each stone weighs at least 25 tons. Stone streets are also arranged with rectangular or polygonal stones of various patterns. A flat-topped pyramid with a height of 42 meters and a length of 54 meters on each side sleeps under water nearly 400 meters from the sea surface. In addition, there are docks, port equipment relics and marble statues.

During 1978, Luo Shiwei, director of the International Diving Center, led a group of team members to visit Bermuda's "Magic Triangle". Suddenly, there was a heavy rain on a sunny day, and the sea was foggy in an instant, and the white light shone directly into the sky. The ship got out of control and they had to give their lives and jump into the sea.

When they dived into the depth of 100 meters, they saw a huge pyramid with two big holes. The sea water passes through the hole at an extremely fast speed, causing turbulent waves and water mist to soar into the sky. It didn't take much time. When this phenomenon disappeared, the sea was calm again.

After careful measurement, they found that the pyramid at the bottom of the ocean is 200 meters high, the spire is 100 meters away from the sea surface, and each side of the tower is 300 meters long. It was built about 7000 years earlier than the Egyptian Golden Pagoda. Because the sea water is too deep and the environment is complex, scientists of underwater survey can't be sure whether the pyramids are contemporary products with other ancient buildings on the bottom of the Atlantic Ocean.

Two years before the discovery of this giant underwater pyramid, scientists found a pyramid in the depths of Bermuda sea just east of it, with its top 700 meters above the water.

Bermuda's latest discovery of submarine civilization sites in the Atlantic Ocean was in 1989, when two Norwegian divers saw an ancient city on an underwater plain in the Magic Triangle.

The two of them took photos with underwater cameras, from which we could see many criss-crossing roads, with buildings with circular roofs on both sides, as well as arenas and rectangular buildings. They are all well preserved. The two Norwegians confidently discovered what Plato called "ancient Atlantis".

In 20 12, American and French scientists, together with other countries, investigated the seabed in the Bermuda Triangle, claiming that a pyramid had never been discovered by human beings. The pyramid is 300 meters long and 200 meters high. The exposed part of the seabed is 100 m from bottom to top. It is preliminarily concluded that this structure is made of glass or glass-like material, because it is completely smooth and partially translucent. ?
