ABOARD KEXUE, June 15 (Xinhua) -- China's research vessel KEXUE (Science) finished its investigation of seamounts in the west of the Pacific Ocean and started to sail back on Saturday evening.
During the expedition, Discovery, a remote operated vehicle aboard KEXUE, made 19 dives and captured more than 800 collections of biological samples, including corals, sponges, shrimps and shellfishes.
"There are about 250 species in the collections, amounting for the total species we had collected in two expeditions in past few years," said Xu Kuidong, chief scientist aboard and a researcher of Chinese Academy of Sciences.
