What's the use of the water glider's first dive for China's military?

According to CCTV news, the research ship "Xiang Yanghong 18", a member of the fleet of Qingdao National Laboratory of Marine Science and Technology, docked at the deep-sea base of the State Oceanic Administration today, successfully completing the 30-day shared voyage mission. "Xiang Yanghong 18" completed the dive observation of 18 sections, including 3 sections with a depth of more than 4,000 m, and the maximum working depth reached 82 13m, which set a new world record for dive depth, obtained a large number of valuable deep-sea observation data, and successfully passed the sea trial.

Diving 6329 meters, the domestic water glider "Haiyi" set a new world record.

According to Xinhua News Agency reported on March 6th, China's self-developed "Haiyi" water glider recently completed the deep dive observation mission in Challenger Abyss of Mariana Trench and recovered it safely, with a maximum dive depth of 6,329 meters, setting a new world record for the maximum dive depth of the water glider.

The reporter learned from the Chinese Academy of Sciences that the "Haiyi" water glider was developed by Shenyang Institute of Automation of the Chinese Academy of Sciences, and it is a new underwater observation platform with completely independent intellectual property rights in China. "Haiyi" dived 12 times on the scientific research ship TS03 of "Exploration 1" for 4 days, with a total working time of 87 hours and a total voyage of over 130 kilometers, breaking the world record of the maximum diving depth of 6,000 meters set by American scientists.

Underwater glider is a new type of underwater robot, which can slide in the water and collect water surface information by adjusting buoyancy and attitude. It has the characteristics of low power consumption and high silence, and can observe water bodies in a large range with high precision in a specific sea area, which can effectively improve the spatial and temporal measurement density of the marine environment and is an effective supplement to the existing underwater observation methods.

It is understood that in this observation mission, the "Haiyi" water glider collected a lot of high-resolution water information in the abyss area, which provided valuable information for marine scientists to study the hydrological characteristics of this area.

During the experiment, "Haiyi" is in good condition, showing good course keeping and data interaction ability under complex current and bad sea conditions. The results of this test will help to improve the diving depth of the "sea wing".
