Chinese scientific research vessel Exploration-2, or Tansuo-2, set out from the coastal city of Sanya in south China's Hainan Province on Sunday to undertake its second-segment sea trail of 2022 deep-sea in-situ scientific experiment station.
Carrying the deep-sea manned submersible "Deep Sea Warrior," Exploration-2 returned home on May 11 after completing a trial mission of a deep-sea in-situ laboratory in the South China Sea.
Aiming to verify the underwater performance and long-term operation reliability of the system, the laboratory is equipped with a number of high-end sensing and detection equipment, including a deep-sea MEMS gas chromatograph, a deep-sea spectrometer and a deep-sea mass spectrometer.
During the expedition, a number of important fluid, sediment and biological samples were obtained in the "Haima" cold spring area and two active cold spring areas to its northeast. Meanwhile, the in-situ laboratory also carried out a 72-hour observation of the fluid composition and microbial community at one hole of cold spring fluid leakage. (CGTN)
China's new manned submersible has passed a state safety test and is preparing for commissioning. The manned submersible, named Shenhai Yongshi, or "deep sea warrior," is able to reach a depth of 4,500 meters. Currently in service is China's manned submersible Jiaolong, which set a record by diving 7,062 meters deep in the Mariana Trench in June 2012.
China's new manned submersible finished the first ocean expedition of its operation stage. The manned submersible, Shenhai Yongshi (Deep Sea Warrior), can reach a depth of 4,500 meters. It conducted 17 dives in 17 days during the expedition, with more than an average eight hours in water per dive.
