The "Haiyan" gliders have undergone a series of standard tests.

 

As part of the six-days of dives, the "Haiyan" gliders are said to have broken the record for a deep-sea dive, hitting a depth of 8,213 meters.

 

The previous record is said to have been around 6,000 meters.

 

"It is a historic step in China's deep-sea observation. The successful development of the deep-sea underwater gliders will guide and stimulate³ the advancement⁴ of China's unmanned deep-sea research equipment," said Wu Lixin, director of the Qingdao National Laboratory for Marine⁵ Science and Technology.

 

Gliders, unlike other unmanned vessels⁷, dive and rise through a shift in the ballast of the vessel⁶, allowing the craft to gain or lose depth in a 'yaw,' or see-saw type descent or ascent⁸.
