Chinese unmanned submersibles on expedition

A Chinese specialist vessel, carrying unmanned submersibles Qianlong No. 1 and Qianglong No. 2, set off on a 170-day scientific expedition in the southwest Indian Ocean on Wednesday.
Xiangyanghong 10, on its maiden voyage on deep-sea areas, set sail on Wednesday from the port city of Sanya in south China’s Hainan Province with an expedition team of 232 members.
During the voyage of more than 24,000 kilometers, the submersibles will explore metal sulfides and conduct environmental and biodiversity surveys in the Indian Ocean in accordance with a contract signed by China and the International Seabed Authority.
According to China’s State Oceanic Administration, China is being more efficient and resource-saving through this new approach of carrying the two submersibles on one ship.
