Core Findings - The research led by the Chinese Academy of Sciences has discovered the deepest known chemosynthetic life communities at a depth of 9,533 meters in the ocean, which do not rely on sunlight for energy [1] - The study revealed large-scale chemosynthetic life communities and methane reservoirs along a 2,500-kilometer stretch of ocean trench, primarily consisting of deep-sea tube worms and bivalve mollusks [1] - The methane in these environments is produced by microorganisms deep within sediment layers, indicating the existence of a previously unknown, active deep biosphere beneath the abyssal seafloor [1] Implications for Ecosystem and Carbon Cycle - The discovery challenges the traditional view that abyssal ecosystems are primarily sustained by organic particles and animal remains sinking from the ocean surface, providing a new perspective on the complex mechanisms of deep-sea carbon cycling [1] - The research suggests that chemosynthetic life may significantly influence the structure of abyssal ecosystems and global carbon cycles, indicating the presence of a "chemosynthetic life corridor" in deep ocean trenches worldwide [2] - This study is part of the "Global Abyss Exploration Program," an international research initiative led by the Chinese Academy of Sciences aimed at uncovering the mysteries of the Earth's deep ocean [2]

Core Insights - The "Global Abyss Exploration Program" has been officially approved by the United Nations "Decade of Ocean Science" Executive Committee, led by the Chinese Academy of Sciences' Institute of Deep Sea Science and Engineering, marking a new chapter in global cooperation in deep-sea exploration [1][5] Group 1: International Collaboration - Chinese scientists will collaborate with researchers from over 10 countries, including New Zealand, Denmark, and Germany, to explore the Earth's deepest ocean "unmanned areas" [1][5] - The program aims to shift international deep-sea science from isolated research to systematic research, promoting the development of the international abyss discipline [5][6] Group 2: Scientific Objectives - The program will focus on extreme environmental life, geological processes, and the impact of human activities on abyssal environments, addressing questions about life origins and evolution [6][5] - Key research areas include the distribution and evolution of abyssal life, plate subduction and geological evolution, deep-sea material and energy exchange, abyssal carbon cycling, and global changes [6][5] Group 3: Achievements and Future Directions - Over the past decade, China has transitioned from "catching up" to "leading" in manned deep-sea exploration, with significant achievements such as the successful joint expedition to the Puysegur Trench involving 68 scientists from 8 countries [5][6] - The program is part of China's broader strategy to deepen international scientific cooperation and participate in global scientific governance, reflecting a commitment to open collaboration in various fields [6][5]
