The “striver” completed 21 10000 meter dives! China ranks first in the number and number of 10000 meter deep dives in the world

CCTV news: the reporter learned from the Deep Sea Institute of the Chinese Academy of Sciences that the “exploration No. 1” scientific research ship returned to Sanya yesterday (5th) after completing the routine scientific research application task of the second leg of 2021

it is reported that this voyage lasted 53 days, carried out the routine scientific research and application of the second segment of the “striver” manned submersible in 2021, and conducted the 10000 meter sea test of deep-sea instruments and equipment, including the “Wukong” all sea autonomous underwater unmanned submersible, all sea glass ball and acoustic releaser

Cao Jian, associate professor of Harbin Engineering University: during the sea trial, the “Wukong” AUV (Autonomous Underwater Unmanned Vehicle) dived four times, and the depth of the four times exceeded 10000 meters, of which the depth of the last three times exceeded 10800 meters, and the maximum depth reached 10896 meters, which can reach this depth, There are only five submersibles in the world

based on the large depth and high-precision operation advantages of the “striver”, a batch of precious abyss water, sediment, rock and biological samples were collected on this voyage, which provided valuable data and samples for the comparison of different abyss special environment, geology, life and other multidisciplinary research

during the voyage, the “striver” manned submersible dived 23 times, of which 6 times exceeded 10000 meters, and conducted scientific research in the deepest area of the “Challenger abyss” in the Mariana Trench

Chen Chuanxu, chief scientist of the segment: this year, the “striver” has completed 51 dives, established an efficient diving mode of five days and three dives, expanded the scope of deployment and recovery to adapt to sea conditions, and trained more divers. These advances enable the “striver” to bring more scientists from all over the world to the deepest place in the world in the future

the number and number of 10000 meter deep dives in China rank first in the world

according to the introduction, 60 scientific research team members from 10 units participated in the mission, and many scientific research team members entered the 10000 meter depth on the “striver” for the first time. The number and number of 10000 meter deep dives in China have ranked first in the world

during this voyage, 17 scientific and technological personnel from 7 units across the country participated in the diving of the “striver” for the first time, including 5 female scientists. In this voyage, eight people dived to a depth of 10000 meters for the first time. Among them, Wang Jian, a 67 year old scientist, became the first scientist in China to complete the investigation of the earth’s south and Arctic regions, climb Mount Everest, the world’s highest peak, and dive to the deepest sea area in the world to carry out 10000 meter scientific research. He is also the oldest person in the world to achieve this record

participating scientist Wang Jian: the wind on the road is too strong and the waves are too high. I haven’t eaten or drunk for a few days. I don’t eat or drink, but I only vomit. However, it’s quite interesting to see a new magical world after I dive (dive) ten thousand meters. (I) I’m glad that as a scientific and technological worker, I can take samples from Mount Everest and make good scientific and technological achievements. I hope I can make good scientific and technological achievements in the deep sea

it is understood that to complete so many diving operations at sea, I often have to face the impact of bad sea conditions. Liu Zhu, captain of “exploration No. 1”, told reporters that to ensure the frequency of three dives in five days, they chose to “fight guerrillas” at sea

captain Liu Zhu of “exploration 1”: We “fight guerrillas” at sea. There are strong winds and waves at this point and we can’t dive. We analyze in detail the diving points that can dive, try to meet the needs of scientists, and let scientists go down as much as possible and make more scientific research on the seabed

from the first 10000 meter sea trial of the “striver” in November last year to the end of this voyage, the “striver” has completed a total of 21 10000 meter dives. 27 scientists from 9 universities, scientific research institutes and enterprises in China have reached the deepest ocean in the world through the “striver” manned submersible. The number and number of 10000 meter deep diving in China ranks first in the world

participating scientists launched the Mariana consensus initiative

during this voyage, the participating scientists team jointly launched the Mariana consensus initiative to establish a standardized platform system for abyssal scientific research, so as to realize the long-term preservation and sharing of abyssal scientific research samples and data, and support international major scientific cooperation around the abyss

it is reported that the Mariana consensus initiative jointly launched by the team of scientists puts forward the requirements of voluntary cooperation and sample collection and sharing

Professor Xiao Xiang of Shanghai Jiaotong University: because the abyss, especially the abyss over 10000 meters, is on the high seas or in some exclusive economic zones, it is also the focus of international peers. I also hope that international peers will work with us in this regard. I believe it is through According to the Mariana consensus, we will certainly do memorable or meaningful work in the field of abyss science.

in addition, “Mariana Trench ecological environment research program” At the same time, domestic and foreign researchers are invited to focus on the scientific research of the 10000 meter abyss in Mariana, and work together to tackle major scientific issues such as the formation and evolution of the deep-sea geoscience system, the origin of life and environmental adaptation, biodiversity and climate change.

participating scientist Xu Xun: Based on such a plan, we will be able to integrate this biodiversity resource in the global abyss One step digitization will further explain the scientific problems of the origin of life and extreme environmental adaptation technology. At the same time, these genetic resources will also contribute to our industrial application
