At 01:00 a.m. local time on April 9, the "Ocean One" ship that was performing the 52nd voyage mission of the Chinese Ocean, the 6000-meter survey sampling unmanned remote control submersible (ROV) "Sea Dragon III" independently developed by China successfully completed the diving task of this station in the middle ridge of the Indian Ocean, with a total of 3 dives in 4 days, and the longest continuous near-bottom observation operation was 6 hours, collecting samples of large benthic animals, clean seawater, benthic fish, deep-sea sediments and other samples. A variety of in situ parameter measurements were performed.

It is reported that the "Sea Dragon III" ROV is supported by the Ocean Association and developed by the team of Professor Ge Tong of Shanghai Jiao Tong University, a new generation of domestic, high-power, operational underwater unmanned remote control submersible, especially suitable for deep-sea scientific expeditions. "Sea Dragon III" has two major advantages: one is that it can achieve large-span, long-distance near-bottom observation and sampling; second, it has the ability to fix and refine operations. In this section, with the cooperation of the mother ship "Dayang I", the "Hailong III" carried a variety of independently developed monitoring probes and sampling equipment to complete the multi-parameter test in the hydrothermal area, fixed-point sampling, marker release, linkage between the mother ship and ROV, long-distance observation near the bottom, photography and video and other functional target tasks underwater.
