Submersible Jiaolong descends to 4,811 meters in Mariana Trench

China's manned submersible Jiaolong finished a dive in "Challenger Deep" in the Mariana Trench, the world's deepest known trench, on May 25, 2017.

The whole dive lasted 8 hours and 50 minutes. During the dive, the submersible reached the planned depth of 4,811 meters, where scientists conducted observation, sampling and surveying, and collected seawater, rocks and samples of marine life, including a sea cucumber, a sponge and two starfish. The submersible also photographed the seabed.

The latest dive was the first of 10 dives planned for the third stage of China's 38th oceanic expedition.
