China's Deepest Diving Sub Is Getting a New Set of Eyes

Studying the creatures of the deep sea—be they Giant Squid or Jaguar Sharks—is no easy feat. It's cold, dark, and nearly inaccessible to humans. But that hasn't stopped us from exploring the furthest depths of the ocean, and with these new 3D cameras China's deep-diving Jiaolong submersible will be able to spot undocumented species in even pitch black waters.

Devised by a team at the Second Institute of Oceanography in Hangzhou, this camera snaps a series of three-dimensional images to build up a composite image of sea creatures. Like all 3-D cameras, this system utilizes two separately-mounted lenses to provide the stereoscopic perspective. This also allows researchers to accurately measure the dimensions of sea life without having to collect samples.

"We are not building the camera to shoot 3D movies, so you probably won't be blown away by the visual effects of the final product. But it will be the most precise visual reconstruction ever of these elusive creatures," Professor Yang Junyi , a marine biologist heading the project told the South China Morning Post. "It may answer some of the biggest mysteries of the deep." Who knows what sorts if exotic life we'll discover seven kilometers below the waves? [South China Morning Post]

While it may not be able to reach the same seven-mile mark as James Cameron's deep-sea vessel, the Jiaolong manned submersible could provide so much more.

The Jiaolong is an 8.2-meter long, 22-ton scientific research vessel and the result of years of stealth development by the Chinese government. It was initially devised as part of the 863 Plan, a high-tech R&D initiative enacted in 2002.

The Jiaolong made its first test-run in 2010, diving to 3000 meters. A subsequent test in 2011 saw the sub dive past 5000 meters, making it one of only five submersibles in the world capable of exceeding 3500 meters—the others belonging to the US, France, Russia and Japan. Tang Jialing, Fu Wentao and Ye Cong comprise the submersible's three-man crew. Ye both helped design the vessel and has been its pilot on 28 of the previous 37 dives.

If the sub does reach its operational limit of 7000 meters during an upcoming test-dive in June, the Jialong will become the only sub of the five capable of diving beyond 6500 meters. At 7km below the surface, the Jiaolong will have access to 99.8 percent of the seafloor—assuming it can withstand the crushing pressure.

With that sort of range, the Jiaolong will play an essential role in deep-sea exploration, both scientific and commercial. The company that helped design and build the submersible, the China Ocean Mineral Resources R&D Association (COMRA) has contracts with the International Seabed Authority to photgraph and survey 75,000km swaths of the seabed in return for rights to "explore minerals and other resources for commercial purposes in this area once the technology matures," said Jin Jiancai, COMRA's secretary-general.

And as the price of precious metals and rare earth element commodities steadily rise, the ability to explore virtually the entire undersea landscape, which covers 70 percent of the Earth, and mine subsequent discoveries are sure to provide a sizable bounty for any country able to reach them. "The range between 6,000 and 7,000 meters below sea level is rich in resources," Yan Kai, the team's chief engineer said. "Therefore, we need to have our submersibles explore and conduct research in this range." [Jiaolong Wiki, BBC News, WSJ, Old Salt Blog, Asian Scientist, Subsea World News]
