Jiaolong, China's deep-sea manned submersible, completed its first dives in the Atlantic Ocean. By February 23, Jiaolong had made 23 successful dives in the southern Atlantic, exploring multiple hydrothermal zones. It collected approximately 300 geological and biological samples, along with 4 terabytes of environmental data and visual materials. Jiaolong is being carried by China's Deep Sea No. 1 research vessel, which departed from Qingdao in east China's Shandong Province on December 17, 2023, and is set to return to China in May 2024.
