Chinas self-developed underwater glider "Haiyan" has broken the world record of deep-sea dive by going down to a depth of 8,213 meters below sea level. The underwater glider, carried on board the submersible mother ship Xiangyanghong 18, returned to eastern China's Qingdao City on Saturday after finishing the dive in the Mariana Trench, known as the world's deepest sea trench.

Storyline
China's self-developed underwater glider "Haiyan" has broken the world record of deep-sea dive by going down to a depth of 8,213 meters below sea level.
The underwater glider, carried on board the submersible mother ship Xiangyanghong 18, returned to eastern China's Qingdao City on Saturday after finishing the dive in the Mariana Trench, known as the world's deepest sea trench.
"We had fully tested the performance of Haiyan deep-sea underwater glider in a series of standard sea trials. During the six-day dive in the waters near the Mariana Trench, it dived as deep as 8,213 meters, breaking the world record depth of about 6,000 meters," said Wang Yanhui, leader of the underwater glider development project.
Experts said the dive is a milestone for China's development of underwater research equipment.
"It is a historic step in China's deep-sea observation. The successful development of the deep-sea underwater glider will guide and stimulate the advance of China's unmanned deep-sea research equipment," said Wu Lixin, director of Qingdao National Laboratory for Marine Science and Technology.
