Submersible sets ocean depth record

Progress continues on craft that can explore the most remote parts of sea

China's unmanned submersible Hailong 11000 - also known as Sea Dragon 11000 - recently set a national depth record for a Chinese robotic submersible, according to the Ministry of Natural Resources.

The ministry, which merged with the former State Oceanic Administration in March, said in a statement on Monday that the record was set during a test dive in the northwestern Pacific Ocean on Sept 1 when the submersible reached a depth of 5,630 meters.
