After 156 days at sea and a journey spanning more than 40,000 kilometers, the Chinese scientific research ship Tansuo-1 returned to Guangzhou City, south China's Guangdong Province, on Sunday with major deep-ocean discoveries.
The vessel carried the deep-sea manned submersible Fendouzhe (Striver), which completed 63 dives, including 50 deeper than 6,000 meters, during a groundbreaking Pacific expedition and conducted the first China-Chile joint crewed exploration of the Atacama Trench.
Scientists from six countries, namely China, Chile, Germany, Denmark, Canada and Spain, collected rare biological and geological samples and captured stunning high-definition footage from some of the deepest places on Earth.
Among the key discoveries was the first finding of an ecosystem supported by geological fluid in the sunless deep sea of the southern hemisphere, providing crucial evidence for the "global chemosynthetic life corridor" hypothesis.
The team also recorded a rich variety of hadal organisms, including at least three types of snailfish, and large numbers of benthic creatures, many of which are believed to be previously unknown species.
In addition, researchers identified seabed fault-rupture structures linked to historic major earthquakes, offering in-situ evidence for understanding how seismic activity shapes deep-sea landforms and affects marine habitats.
