Core Insights - The "Fendouzhe" manned submersible successfully completed 43 dive missions in the Arctic, collaborating with the "Jiaolong" submersible, marking a significant advancement in underwater cooperative operations for China [3][4]. Group 1: Mission Overview - The mission was organized by the Ministry of Natural Resources and the Chinese Academy of Sciences, utilizing the "Exploration No. 3" vessel and the "Fendouzhe" submersible for manned deep-sea exploration in the Arctic [3]. - The expedition lasted 56 days, during which the team conducted a series of scientific investigations and experiments in the Arctic Ocean [3]. - The maximum dive depth achieved was 5,277 meters, representing the first manned deep-sea exploration of the Gakkel Ridge in the Arctic [3]. Group 2: Scientific Contributions - The "Fendouzhe" submersible collected valuable samples of Arctic water, sediments, rocks, and biological specimens, providing significant observational data for research on rapid climate change in the Arctic and the evolution and adaptation mechanisms of life in extreme environments [3][4]. - The mission validated the operational capabilities and application value of the "Fendouzhe" submersible and the "Exploration No. 3" vessel in polar ice regions, achieving breakthroughs in domestic technology for deep-sea exploration [4]. Group 3: Technological Innovations - The expedition pioneered a new mobile ice-diving model of "ship-submersible cooperation" in dense ice areas, positioning China as the only country currently conducting continuous manned deep-sea dives in the Arctic's dense sea ice [4]. - The "Fendouzhe" submersible and the "Jiaolong" submersible completed over ten dive missions in the Arctic, engaging in underwater cooperative tasks such as positioning searches and underwater motion photography [4].
