May 13, China's self-developed 4500-meter manned deep submarine "Deep Sea Warrior" in the South China Sea region again made important discoveries, diving for more than 8 hours.
It is worth noting that the "Deep Sea Warrior" deep dive, ushered in the oldest "passenger" - China's famous marine geologist, academician of the Chinese Academy of Sciences, "South China Sea deep program" steering expert group leader, Tongji University School of Ocean and Earth Sciences Professor, 82 years old Wang Pinxian.

After diving 1,410 meters and eight hours of deep-sea work, Wang walked out of the manned module with a big smile on his face and announced happily, "Today's dive in the Xisha Sea area has yielded important discoveries. Just after the deep submerger reached the seafloor, it discovered a cold spring biota dominated by tubular worms and mussels. Thereafter, in the basalt area, a special biota of cold-water corals and sponges was found, which can be called the cold-water coral forest of the Xisha deep sea. This is well worth further in-depth study in the future." ?
In fact, deep-sea scientific research is already familiar to Wang Lao. It was found that Wang Pinxian had participated in the South China Sea scientific research four times after he was 60 years old, but it was the first time he took China's own ship and self-developed manned deep-submersible to observe the seabed of the South China Sea with his own eyes.
But although Wang was elected academician of the Chinese Academy of Sciences in 1991, it wasn't until China's participation in the International Ocean Drilling Program (ODP) in the 1990s that he formally started his deep-sea scientific research in a practical sense. Wang even jokingly said that others are post-doctoral, he is "academician after".
The 10,000-meter manned deep submarine "Jiaolong" screening test for divers includes six major aspects and 119 criteria. The harsh standards stem from the deep sea is not friendly to the scientific research team members: sea conditions are bad, to overcome the violent bumps driving the submersible dive, and even have to lie on the bed with a quilt to "squeeze" themselves, to prevent the roll; submersible diving, in order to save energy, the cabin does not open the lights, the cabin outside the darkness, especially the test of the psychological quality of the people; in addition, the dive once, manpower, financial and human resources, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, the dive, and the dive. In addition, the submarine dives once, manpower and financial resources are consumed greatly. Therefore, the scientific research team members work underwater operation, basically no time to rest, either in an operation point operation, or on the way to find the next operation point operation.
It can be said that not only China, but also all over the world, deep-sea exploration is lagging behind relative to other areas of exploration, and it symbolizes economic and technological rivalry.
In fact, Wang's first expedition to the South China Sea took place in 1999, when he was 63 years old and led the team as chief scientist. Before leaving on that mission, Mr. Wang left a message for his wife, "If you can come back alive, you win."
In those days, in addition to the enormous pressure of work, deep-sea scientific research also had to face multiple problems such as pirate attacks and technical equipment failures, which can be said to be a hair pulling the whole body. In the two months of scientific research, he only dared to rest for a short while every day, and his biological clock was completely disrupted. However, Wang Pinxian successfully completed the first ocean drilling voyage designed and hosted by Chinese people, realizing the zero breakthrough in deep-sea scientific drilling in China's oceans and achieving a series of gratifying results.
Ocean drilling is an international cooperative project, the drilling ship is American, and most of the captains and crews are Americans. What Wang still can't forget is the scene when the captain ordered to raise the Chinese flag when the first well was drilled. The significance of this has far exceeded the scope of science, so that the inspiration "through their own efforts in scientific research, for the country to regain confidence in the sea," Mr. Wang passionate.
