Exploration one ship to get three international scientific research breakthroughs, the ten major scientific research achievements

According to Xinhua News Agency Chinese academy held a press conference on the 23 day, announced significant achievements in the field of scientific research. In June this year, Chinese Academy of Sciences "exploring a ship TS01-01 voyage in Mariana Trench the Challenger deep out of my country first comprehensive million meters deep in the international field of deep-sea expedition, carried out a series of pioneering work, made a breakthrough, marking China's deep-sea expedition into the era of 10000 meters.

In June 22nd this year to August 12th, China Academy of Sciences "exploring a ship TS01-01 voyage, using self-developed" sea Doo "unmanned submersibles," the horizon ", and" the Cape "abyss lander," in situ experiment "abyss lifter and a host of other deep-sea equipment, to carry out the Challenger deep in the Mariana Trench China's first comprehensive million meters deep expedition voyage, which lasted 52 days, 37 days work, performing 84 equipment test and research tasks. Among them, three meters level equipment 5 times more than ten thousand meters depth, to obtain a large number of precious samples and data. This is China's first in the history of marine science and technology Ciwanmi class deep-sea expedition, is to achieve the "13th Five-Year" national key research plans to deploy manned / unmanned meters deep technology target early efforts, marking China's deep-sea expedition into the era of 10000 meters.

The 10000 meter abyss expedition, won three major international scientific breakthroughs:

In the 10000 meters depth, in situ experiment, experimental device equipped with lifting device abyss at the bottom of the sea successfully carried out at the bottom of the abyss of the nitrogen cycle in situ cultivation experiment, "the horizon", abyss lander single access to a large number of submarine water samples (>100 L), which in the same or similar equipment are without precedent.

The use of domestic submarine seismic instrument (OBS) for the first time in the Challenger deep in the west to carry out active artificial seismic exploration, the success of a complete seismic profile.

Using the marine winch system and sediment sampling equipment, 9150 meters water depth of the box type sediment samples, creating a new record of the same type of deep-sea equipment operating depth.

At the same time, the sea voyage in the domestic field is also a pioneering work and achieve a breakthrough:

China has independently developed the "sea Doo" unmanned submersibles carried out a successful 8000 meters, two meters and 9000 level two level Ciwanmi dive application, maximum dive depth of 10767 meters. So that China has become the following day, the United States and the United States after the third have developed ten thousand meters unmanned submersible capacity of the country.

China has independently developed the underwater glider dive depth of 5751 meters, close to the current international underwater glider maximum dive depth (6000 m), a record of China's underwater glider maximum diving depth record.

Domestic submarine earthquake (OBS) depth of work for the first time exceeded 7000 meters. The voyage spent a total of 9 sets of OBS equipment, the recovery rate is 100%, the maximum operating depth of 7731 meters, set a new record of domestic seismic instrument work depth.

China has independently developed the "Cape" and "Horizon", "the abyss of the lander in situ experiment" pit lifter were 17 times greater depth, the "end of the world" and "in situ experiment" No. three breakthrough million meters depth, maximum depth of 10935 meters.

The high precision positioning performance to explore the dynamic positioning system, DP2 ship, and 10000 meters sounding detection system, CTD water sampler, sediment sampling device, seismic experiment system of shipborne equipment to run successfully, that the "explore" the boat as China's 4500 meters and meters of manned / unmanned submersibles mother ship and comprehensive deep sea Doo expedition work platform, with 6500 meters in the conventional deep ocean exploration work and the ability to support the operation of meters deep dive expedition.

The use of the "sea bucket" unmanned submersible was successfully obtained 9000 2 meters (9827 and 9740 meters) and 2 meters level (10310 and 10767 meters) of water column temperature and salinity data. This is our country to get the first ten thousand meters deep salt profile data, the spatial variation and deep bottom water structure as the research characteristics of the water bucket sea depths, to provide valuable basic data and design M manned submersible.

Through the depths of the lander and lifting device were carried out in 13 times the potential biological trapping experiments, obtaining two large biological samples in the 5000 meters, 6000 meters, 7000 meters, 8000 meters, 9000 meters and 10000 meters depth. These deep and large organisms provide valuable samples for the exploration of the origin and evolution of the species, population genetic characteristics and the adaptation mechanism of symbiotic microorganisms to the extreme high pressure environment.

Use of marine sediment collection equipment and the abyss of the lander, the success of the depth of the complete sequence of the seabed sediment samples, from 7000 meters, 8000 meters, 9000 meters to the maximum depth of 10822 meters. Large depth sediment samples were obtained for the study of the global climate change, the response of the global climate change, the early diagenetic activities, and the intrinsic relationship between chemical and geological activities.

Using the ship water sampler, the abyss of the lander, the elevator, the success of the depth of the complete sequence of the Mariana Trench water samples, including 7000, 8000, 9000 and ten thousand meters of water samples, the maximum sampling depth of 10900 meters. The acquisition of large depth water samples provides a valuable research sample for the study of the ecological environment evolution of the deep water body, the circulation of the abyss and the research of the extreme high pressure microbiology.
