During this mission, the Unmanned Surface Vehicle collected over 700 consecutive days of air–sea interface observation data, covering key parameters such as air temperature, atmospheric pressure, wind speed, wind direction, sea surface temperature, wave height, and wave period. The dataset provides comprehensive, continuous, and high-precision observations of the air–sea interface in the Northwest Pacific Ocean, offering valuable first-hand data for marine science research in China and worldwide.

The key achievements and highlights of this mission are as follows:

[Navigation Achievements]

• The Unmanned Surface Vehicle completed a cumulative sailing distance of over 20,000 km, equivalent to approximately half the circumference of the Earth at the equator. 
• It successfully passed through more than 10 typhoon-affected regions, demonstrating the exceptional wind and wave resistance capability of the “Black Pearl” platform. 

[Observation Data]

• More than 40,000 sets of air–sea interface observation data were collected, covering critical parameters including air temperature, atmospheric pressure, wind speed, wind direction, sea surface temperature, wave height, and wave period. 

[Technological Advances]

• Key independently developed technologies were achieved, including an efficient wave energy conversion system, autonomous navigation control system, data transmission and communication system, and adaptive energy management system, enabling long-endurance and long-range autonomous operation. 
• Significant breakthroughs were made in long-term stability and reliability, including enhanced corrosion resistance and fatigue resistance of the mechanical structure, as well as redundant design of navigation and communication systems. 

The successful completion of this mission not only demonstrates the technological strength of China’s “Black Pearl” Unmanned Surface Vehicle, but also provides important support for global climate change research.

We will continue to advance innovation in marine observation technologies, further expanding the application and impact of Unmanned Surface Vehicles in promoting marine science development, ensuring sustainable utilization of marine resources, maintaining marine ecological balance, and safeguarding national security.
