What is the scientific mission and significance of Xiaolong?

Scientific mission: China is the fifth country in the world to master the technology of deep manned submersible after the United States, France, Russia and Japan. In the global manned submersible, Jiaolong belongs to the first echelon. Jiaolong is a project supported by the National 863 Program, which has achieved breakthroughs in key technologies such as pressure-resistant structure, life support, long-distance underwater acoustic communication and system control.

Significance: It can be used in the vast sea area accounting for 99.8% of the world's ocean area, which is of great significance to the development and utilization of deep-sea resources in China.

Expand the application fields of data:

1. Take scientists and engineers into the deep sea, maneuver, hover, correctly position and sit on slopes in seamounts, ridges, basins, hydrothermal vents and other complex seabed, and effectively carry out scientific investigations on marine geology, marine geophysics, marine geochemistry, marine geological environment and marine life.

2. The "Jiaolong" has the functions of deep-sea prospecting, seabed high-precision topographic survey, suspicious object detection and capture, and deep-sea biological survey. It can explore polymetallic nodule resources, finely measure community topography, obtain nodule samples, water samples, sediment samples and biological samples at fixed points, and evaluate the coverage and abundance of polymetallic nodules through video and photography.

Measure the temperature of polymetallic sulfide hydrothermal vents, collect water samples around the hydrothermal vents, and keep the hydrothermal water samples truthfully. Explore cobalt crust resources, use DTH to conduct core sampling operation, and measure the coverage and thickness of cobalt crust deposits; It can carry out fixed-point deployment of underwater equipment, submarine cable and pipeline detection, and complete other complex operations such as deep-sea inquiry and salvage.
