“奋斗者”号载人潜水器带着北极深海故事回来啦！

Core Insights - The "Fendouzhe" manned submersible successfully completed its Arctic deep-sea mission, returning after 98 days and covering over 15,000 nautical miles [1] - A total of 43 dive operations were conducted, including the first manned deep-sea scientific exploration of the Gakkel Ridge in the Arctic [3] - China is now the only country capable of conducting continuous manned deep-sea dives in densely ice-covered areas of the Arctic [3] Summary by Sections - Mission Accomplishments - "Fendouzhe" completed 43 dive operations during its Arctic mission [3] - The submersible spent an average of over 9 hours underwater per dive, with over 6 hours of operational time on the seabed [3] - The mission involved collaboration with the "Jiaolong" submersible for positioning and marker exchange, innovating China's dual manned submersible operational model [3] - Challenges Faced - The primary challenge in the Arctic was navigating "moving icebergs," which posed risks during ascents and descents [4] - The submersible had to avoid drifting ice, requiring high sensitivity and real-time adjustments due to rapid changes in light and temperature conditions [6] - Scientific Contributions - The mission returned with water, sediment, rock, and biological samples from the Arctic, along with extensive observational data [8] - These findings will support further research on Arctic climate change [8]
