The Chinese scientific research vessel Tansuo 1 arrived in Guangzhou, Guangdong province, on Sunday after completing the first China-Chile joint manned deep-sea expedition to the Atacama Trench off the coast of Chile, marking a major step forward in international marine scientific cooperation and China's active participation in global ocean governance.
The hadal trench — the ocean's deepest layer below 6,000 meters -is one of the least understood scientific frontiers, but it is key to studying life under extreme conditions, uncovering the mechanisms of earthquakes and tsunamis, and identifying unique genetic resources.
