The recent successful deployment of the ROV explorer Haiqin in the South China Sea marks a significant technical step forward for underwater underwater research in Asia. Designed by Shanghai Jiao Tong University, this unmanned submersible reached a depth of 4,140 meters during its first mission, validating its operational capability for missions up to 6,000 meters.
Haiqin Explorer in the service of ocean science
The Haiqin is a remotely operated vehicle (ROV) (ROV) that features high-definition cameras, robotic arms, sonar systems and precision sensors. These tools enabled the researchers to to collect biological samples and sediments from the seafloor, which were transferred to thewhich were transferred to the research vessel Zhong Shan Da Xue, operated by Sun Yat-sen University.

Haidou-1, a complete autonomous deep-ocean vehicle, was also deployed during this expedition. This is the first time that two submersibles of different technology have operated simultaneously from a single support vessel on a Chinese mission. This coordination made it possible to extend the scope of marine surveys and optimize data collection.
Implications for the study of biodiversity and marine geology.
The double deployment made it possible to make precise observations of the seafloorThe dual deployment enabled precise observations of the seafloor, the capture of organisms from abyssal zones and the collection of data on underwater geological processes. Preliminary results suggest that such combined operations could accelerate discoveries of extreme biodiversity and provide unique data for genetic and climate studies.
This achievement strengthens China’s technological capabilities in deep-sea exploration, adding to a series of developments aimed at positioning the country as a leader in ocean science. Both Haiqin and Haidou-1 will remain active on future missions, aligned with a national strategy that boosts knowledge of the marine ecosystem and deep-sea resources. resources of the deep sea..
With this operation, China demonstrates that its commitment to technological autonomy also reaches the most unexplored areas of the planet.
