Submersible's recovery could detail origins of South China Sea formations, scientists say

ABOARD THE XIANGYANGHONG 09 - Jiaolong, China's manned submersible on Saturday retrieved a basalt sample from the Zhenbei Seamount in the South China Sea which scientists say could shed light on the formation and evolution of seamounts in the area.

Jiaolong stayed underwater for 9.5 hours in its third dive in the second stage of China's 38th ocean scientific expedition, which will last until May 13.
