Discovery of new underwater microscopic species

In his thirst for knowledge, man has long led expeditions in various places on the surface of the planet. However, when it comes to the oceans, little has been discoveries until now. Thus, recently, scientists carried out a long deep sea underwater exploration in order to lift the veil on certain questions that hover in their minds.

To achieve this, they used a very sophisticated submarine that can reach a dizzying depth of 8,000 meters which had never been explored before. The expedition took place in the Atacama Cavityresulting from the collision of two tectonic plates in the eastern Pacific aquifer, where interesting discoveries have been made.

Victor Vescovo as well as the deputy director of Millennium Ruben Escribano took part in the expedition. In addition, the voyage lasted 12 weeks throughout the north coast of chile in a vacuum of 5,900 kilometers.

New species buried in underwater sinkholes

At some depth in the dark waters of the Atacama pitresearchers were flabbergasted by the discovery of new genera of bacteria and living organisms. Curiously, some of these species have traits of similarity with well-known living beings on the surface. However, those that have been seen in the abyss bear additional characteristics that arouse the curiosity of researchers.

“We discovered geological structures that housed transparent sea cucumbers, like compote, which is still unknown and which is most likely a new species. We also unearthed bacteria that had filaments never encountered in the Atacama pit. These living beings live on organic substances found in water. »

Atacama Hadal, a very first descent into the underwater abyss

Throughout their expedition, these researchers came close to unexplored depths until this day. Indeed, the submarine that served as the vehicle for this boat trip troubled waters was able to reach a depth of more than 8,000 meters under water. Therefore, it was only possible to see within range of the powerful LEDs of the submersible.

“This underwater expedition was an opportunity to reach depths still unexplored to date by men. »
