"Jiaolong" discovered 27 new dark ecosystems in the Indian Ocean

Xinhua News Agency, Sanya, April 6th (Reporter Liu Shiping) The "Xiangyanghong 09" ship carrying the "Jiaolong" manned submersible and all the scientific expedition team arrived at Sanya's Phoenix Island Wharf on the evening of the 5th, announcing the 59-day China Ocean 38 The mission of the first leg of the voyage ended successfully

Successfully discovered the first manned deep dive in 27 submarine "black chimneys" and dark ecosystems in the Northwest Indian Ocean

"It is the first time in the world to conduct a scientific survey of manned dives in the Karsberg Ridge hydrothermal area of ​​the Northwest Indian Ocean

"Black Chimney" is a hydrothermal vent.

At the same time, scientists collected a full set of samples of rocks, sulfides, metal-bearing sediments, bottom water, hydrothermal fluids, etc.

Han Xiqiu said that the results obtained from the investigation are the in-depth development of magmatism and its evolution, sedimentation, tectonism, hydrothermal plume structure, hydrothermal action and evolution, sulfide mineralization, sulfide resources and microorganisms.

The construction of the deep-diving professional talent team is in full swing, and the "Jiaolong" has taken a solid step towards commercial operation

As the trainee submarine Zhao Shengya completed the 131st sub-primary piloting task of the "Jiaolong" on March 19, China's second batch of 6 trainee submarines completed the first round of independent piloting of the "Jiaolong" deep-sea operations

At the same time, the deputy commander-in-chief of the practice submersible and the deputy commander-in-chief of the practice surface support system independently completed all command tasks for the deployment and recovery and underwater operations of the submersible for the first time

"Breakthroughs have been achieved in the capabilities of submarines and technical support personnel, and the pilot application of the'Jiaolong' has taken a solid step towards commercial operation

According to reports, this segment has completed 9 person-times of surface support system practice deputy commander training, 3 person-times of submersible body practice deputy commander training, 6 person-times of diving operation department head training, and 3 person-times of submersible preparation department head training.

"Jiaolong" scientific application advantage highlights the need to speed up technological upgrading

The "Jiaolong" was the first to dive into the hydrothermal area of ​​the complex terrain environment in the Northwest Indian Ocean.

"The overall technical status of the Jiaolong is stable, the performance of various systems and equipment is reliable, and the successful completion of the operational objectives and tasks, once again verifying the unique technical advantages of the manned submersible in the complex deep-sea environment

However, he also said that the "Jiaolong" has been successfully developed for more than 10 years to the current experimental application.

The Oceanic 38 voyage, which started from Qingdao on February 6 this year, was divided into three segments, and carried out scientific investigations of ocean resources and deep-sea frontiers in the Northwest Indian Ocean, South China Sea, Yapu Trench and Mariana Trench
