中国科学院深海所2016年在海南三亚正式运行。4500米级载人潜水器"深海勇士"号和全海深载人潜水器"奋斗者"号于2017年和2021年在这 里相继交付使用，有力支撑了我国深海考古、深渊科考等领域的发展。截至今年9月底，"深海勇士"号已累计下潜858次，"奋斗者"号累计下潜 441次，下潜次数和运维能力国际领先。 央视网消息：深海蕴藏着地球上远未认知和开发的宝藏，但要得到这些宝藏，就必须在深海进入、深海探测、深海开发方面掌握关键技 术。今天（10月4日）的《强国新基石》系列报道，我们就带您走进我国用于深海探测的两个"大国重器"。 "十四五"期间，依托"奋斗者"号展开的"全球深渊探索计划"，吸引众多国内外科研团队参与，实现万米深潜探索常态化，为抢占国际深海 科学制高点奠定了坚实基础。 载人深潜"双子星" 勇闯深海无人区 "深海勇士"号和"奋斗者"号在解锁深海的征途上，如"双子星"般闪耀。这两个大国重器究竟有何绝招？又有哪些最新的探索计划？来看总 台央视记者的探访报道。 记者来到海南省三亚市救助局码头，"深海勇士"号载人潜水器刚刚完成一个航次的任务靠岸。要说国庆去哪里？这位"深海勇士"要去南海 出差，进行一个月左 ...

Core Insights - An international research team led by the Deep Sea Research Institute of the Chinese Academy of Sciences has discovered the deepest known chemosynthetic life community at a depth of 9,533 meters in the Northwest Pacific Ocean [1][2] - The research utilized the "Fendouzhe" manned submersible to directly observe the largest and deepest chemosynthetic life community, primarily composed of deep-sea tube worms and bivalve mollusks [1] - This discovery may reveal new metabolic pathways and extreme pressure adaptation mechanisms, contributing to the understanding of life in the abyssal zone [1] Research Program - The study is part of the Global Hadal Exploration Programme (GHEP), a 10-year international research initiative aimed at uncovering the mysteries of Earth's deep-sea regions [2] - The research team has planned additional exploration missions to further investigate the global distribution patterns of chemosynthetic ecosystems and their potential impact on the global carbon cycle [2]

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]
