"Haima" is China's first operating system for a 4,500-meter-class remotely controlled deep-sea unmanned submersible. In this series of Haiyang 6 scientific expeditions, based on the "Haima" operation platform, China has achieved a number of technological breakthroughs in deep ocean scientific research.

"Haima" unmanned remote-controlled submersible in the seabed to grab coral

Now you see the picture is "Haima" unmanned remote-controlled submersible in the depth of about 2000 meters to grab coral. And this one is in an area of massive cobalt-rich crust on the seafloor based on observations made by the Seahorse camera. In this expedition, based on the "Haima" operation platform, a detailed in-situ detection technology and method system for cobalt-rich crust has been formed, integrating high-definition video, high-frequency acoustic detection and a variety of sampling tools.

Yang Yong, Chief scientist of "Haiyang 6" voyage: Completed China's first cobalt-rich crust scale sampler sea test. The high frequency acoustic thickness profile of the cobalt-rich crust has been continuously detected for the first time. Using the three-point laser system, the real-time intelligent processing and analysis of the online video data of the submarine camera is realized.

In addition, the "Ocean 6" series of scientific surveys also successfully obtained Marine microplastic samples along the Western Pacific Shipping route, providing basic information for China's deep participation in the international control of Marine plastic waste.
