Divers reached the bottom of the Great Blue Hole for the first time

Divers reached the bottom of the Great Blue Hole for the first time and were amazed by what they saw in this sinkhole.

A group of fans dove into the depths of this mysterious crater in the Caribbean and discovered what this wonder of Mexico and Belize is made of.

The world is full of mysterious natural places that have spent hundreds of years without knowing how they were created or what function they served there.

And what is a blue hole? 

His name is eloquent. The blue-hole, in English, are underwater caverns or sinkholes, natural geological formations that usually occur in karst systems such as the Yucatan, formed from the dissolution of limestone. One of their great peculiarities and that differentiates them from the enormous marine trenches and abysses formed by the movement of tectonic plates, depressions that can reach up to 11.000 meters deep, as is the case in the Marianas, is that the blue holes are They create with the flow of seawater in limestone soils over centuries. 

The Great Blue Hole, the biggest mystery in Central America

Great Blue Hole

One of the biggest unknowns in Central America is the "Great Blue Hole", a volcanic crater at the bottom of the Caribbean Sea, which only in 2018 was it possible to decipher what was hidden in its depths.

This hole is not the only one that exists in the world, there are others scattered in different oceans, but here it is the second deepest: 274 meters. It is located very close to the border of Mexico and Belize, on the southeast coast of the Yucatan Peninsula.

Swimming in its waters is impressive and easy to spot from the air as it is surrounded by small land masses and coral reefs.

In the Mayan language, it is known as Taam ja', which means "deep water" and it was Jacques Cousteau who made it famous throughout the Earth in 1960.

Although he never dared to dive inside, his grandson, Fabien, and the billionaire owner of Virgin Group, Richard Branson, had the idea of ​​traveling to the bottom by submarine.

Six years ago the first survey was carried out in the crater and what they found inside left them stunned. As the submarine moved, the water became darker and darker until they encountered a layer of hydrogen sulfide. After this layer, no more bacteria, fish or algae were found.

The device advanced and discovered several caves with stalactites, which caught the attention of scientists because until now it was always thought that they only formed on the surface of the Earth.

Continuing their journey through the Great Blue Hole, they were already a few meters from the ground but they did not touch it. There they saw a 2-liter glass bottle and a GoPro camera. This shows the extent of the Marine contamination and the distance that garbage can travel. Regrettable.

However, this was not the only thing they found during the expedition. To his surprise, two corpses appeared. It is believed that there were two divers who did not manage to surface. Both Richard and Fabien informed the Belize government of their existence, but decided to keep them there.

What is the inside of the Great Blue Hole like?

According to the magazine Frontiers Marine Sciences, which published on February 23, 2023 a study on what is inside the Great Blue Hole, in addition to its size and other interesting data, in the sinkhole there are important variations in conditions such as oxygen concentration, chemistry, temperature and biological formations .

Taam ja' has an area of ​​about 13.690 m2, the sides are almost vertical and form a "large conical structure". The door or entrance is located 4,5 and 5 meters below sea level.

Unlike ocean trenches, which are created by the movement of tectonic plates and can be up to 11.000 meters deep, blue holes form slowly from salt water moving in and out of the ground, which is made of limestone rock.

The world's largest blue hole is located at Sansha Yongle in China. It is 300 meters deep and is called Dragon Hole.
