China’s Fendouzhe deep-sea manned submersible successfully completed sea trials at a depth 10,000-meters, according to reports.

Fendouzhe set off on Oct. 10 for the 10,000-meter-deep-sea diving operation in the Mariana Trench. During the expedition, it completed 13 dives, eight of which exceeded a depth of 10,000 meters.

The submersible set a national record by diving to a depth of 10,909 meters in the Mariana Trench at 8:12 a.m. on Nov. 10, and returned to the port in Sanya, south China’s Hainan Province, on Saturday morning onboard the scientific research ship Tansuo-1.

The expedition team overcame difficulties such as typhoons, rain and high temperatures, conducted multiple tests and obtained a batch of sediment, rock and seabed biological samples, according to the Ministry of Science and Technology.
