蛟龙号将在太平洋西北部深潜
China's manned submersible Jiaolong departed from south China's Shenzhen for deep-sea dives in the northwestern Pacific Ocean on Tuesday.
中国载人潜水器蛟龙号周二离开深圳港，开赴太平洋西北部海域进行深海潜水。
During the mission, which runs until June 18th, the submersible is expected to conduct nine deep dives in the Yap and Mariana trenches.
The Yap Trench has a depth of over 8,500 meters, and Mariana Trench, the deepest known point in the Earth's oceans, has a depth of over 11,000 meters.
The scientists plan to study deep-sea biotic communities and gene resources in the mission.
Jiaolong completed a dive in the northwestern Indian Ocean earlier this year during the mission's first stage.
