Increased frequency of deep-sea dives requires more trained crew

China will have six new oceanauts, including two women, before the end of November for its deep-sea exploration program, with the recruitment launched on Tuesday.

"Compared with Fu Wentao and Tang Jialing, the country's first two oceanauts, we have higher requirements for the new recruits, who must also be scientists, in the future dives," said Liu Baohua, deputy director of the National Deep Sea Center, at a news conference in Beijing on Tuesday.
