Chinese submarine logs new depth milestone

A Chinese mini—submarine dove 5,057 metres Tuesday in the Pacific Ocean as it seeks to claim the title of deepest—diving submersible, the state—run Xinhua news agency reported.

"At a depth of 5,000 metres, the Jiaolong withstood great pressure amounting to 5,000 tonnes per square metre," the deputy director of the diving operation, Wang Fei, told state news agency Xinhua.

At that depth, he said, the sub could reach over 70 percent of the world's sea bed. It's an interesting way of looking at things, given that last year Jiaolong was used to plant a Chinese flag on the seabed of the hotly-disputed South China Sea, which is rich in oil and gas.

The Jiaolong did not reach the 6,500 metre—depth, set by the Japanese Shinkai submersible in 1989, but its designer said it could eventually dive 7,000 metres. The State Oceanic Administration plans such a dive next year.

The Jiaolong project, which began in 2002, is part of a programme by China to explore the seabed for raw materials.

The Oceanic Administration told Xinhua that Tuesday’s dive of the 8.2—metre—long, 22—ton Jiaolong with three men aboard was a success.

The dive was in international waters in the north—eastern Pacific between Hawaii and North America.

Japan and China are among five countries capable of diving to depths greater than 3,500 metres. The others are the United States, France and Russia.

The overall record for submersible diving was set in 1960 by the Swiss oceanographer and engineer, who travelled to the bottom of the Mariana Trench 马里亚纳海沟(太平洋海底), a depth of nearly 11,000 metres, in the submersible Trieste 特里雅斯特号.
