Jiaolong stayed underwater for 9-and-a half hours in its third dive in the second stage of China&`&s 38th ocean scientific expedition. The maximum depth of the dive was 2,930 meters below the ocean surface.Aside from the 5 kilogram basalt sample, the ship also brought back samples of sediments and seawater from near the seabed, as well as other biological samples. High-definition photos and video footage were recorded.A researcher with the State Oceanic Administration said it is not easy to acquire such a basalt sample. The valuable rock will lay the foundation for the study of the formation and evolution of seamounts in the South China Sea. It is very important for the study of the region&`&s structural evolution.Jiaolong completed four dives in the South China Sea. The oceanic scientific expedition started in February. Earlier this year, Jiaolong completed a dive in the northwestern Indian Ocean. It will travel to the Yap Trench and the Mariana Trench later this year.Named after an auspicious mythical dragon, the Jiaolong made its deepest dive in the Mariana Trench in June 2012, at 7,062 meters.You&`&re listening to Special English.
