China’s manned submersible "Jiaolong" has finished this year’s last scientific dive over a seamount in the western Pacific Ocean. This is its fifth dive in the western Pacific Ocean this year.

After a nine hours scientific dive on Monday, "Jiaolong" returned to Jiangyin City in east China’s Jiangsu Province with its support ship, the Xiangyanghong-09. "Jiaolong" made the last descent of 2,400 meters underwater, which is the height of halfway of the seamount, known as Caiqi Guyot. It brought back underwater creatures and cobalt-rich crust, which will be used for further scientific experiments.

Liu Feng, chief commander of the mission, said the success of the dive, confirmed the submersible’s capabilities, the experienced crew members and supported China’s further underwater research by collecting a rich amount of sea bed dwellers.
