Zhang Yi, 27, was in charge of communicating with the sub's support ship, operating the camera and observing obstacles through the left window during the dive.
"I piloted Jiaolong in testing pool last year and it was very cool," Zhang said prior to the dive, "I think it will be more exciting to dive in ocean and I have been looking forward to this dive for months."
In this dive, Jiaolong was expected to collect some samples of rocks, sulfide, hydrothermal fluid and living beings in this hydrothermal area, said Yu Hongjun, chief commander of the expedition.
