新华社广州12月10日电（记者周颖、邓瑞璇）记者10日从中国地质调查局获悉，该局"海洋地质六号"科考船圆满完成深海地质调查第15航次 第二航段任务返回广州，正式对外发布取得的多项成果。 本次科考自8月29日启航，历时95天，总航程12673海里，在深海环境调查、深海探测关键技术与装备应用等方面取得多项成果。 中国地质调查局广州海洋局"海洋地质六号"船技术负责人宋来勇介绍，此次科考在西太平洋中央裂谷完成"十四五"国家重点研发计划项目支 撑研发的海底电磁采集站海试任务，首次开展太平洋深渊电磁剖面测量，最大投放深度7663米，获取了高质量电磁观测数据，为后续开展地球深 部构造演化和大洋科学钻探选址研究等提供装备与数据支撑。 此次科考获取了一批海洋环境数据和深层海水、海底沉积物、多金属结核、海洋生物等样品，为深海地质研究和海洋环境管理等提供了基础 支撑。深海探测关键装备应用也取得创新进展，首次在太平洋深水区实现6000米级深海遥控潜水器和自主式水下机器人联合开展近海底高精度试 验作业。 "海洋地质六号"科考船回收6000米级电动深海遥控潜水器。新华社发 "这些数据资料和地质样本非常珍贵，可以为我们研究深海地质、深海环 ...

Core Viewpoint - The successful launch of China's first independently designed and built deep-sea drilling vessel "Dream" marks a significant advancement in the country's deep-sea exploration technology and capabilities, breaking multiple world records and establishing a new benchmark in the industry [1][7]. Group 1: Vessel Specifications and Capabilities - "Dream" has a maximum drilling depth capability of 11,000 meters, making it the only deep-sea drilling vessel globally capable of penetrating the Mohorovičić discontinuity (Moho) [3][4]. - The vessel's total length is 179.8 meters, width is 32.8 meters, and height is 81.2 meters, equivalent to a 25-story building, with a maximum variable load of 15,000 tons [3][4]. - It can operate for 120 days without resupply and withstand super typhoons of up to level 16, improving operational efficiency by 60% compared to foreign counterparts [4][5]. Group 2: Technological Innovations - "Dream" features a modular design that integrates functions for ocean scientific drilling, deep-sea oil and gas exploration, and natural gas hydrate investigation, which is a significant challenge globally [1][4]. - The vessel includes the world's first hydraulic lifting drilling machine that combines oil and gas exploration with core drilling capabilities, enhancing drilling efficiency and hard rock penetration [4][5]. - It houses a comprehensive onboard laboratory with nine experimental functions, making it the largest and most versatile "mobile laboratory" at sea, with nearly 40% more space than foreign vessels [4][5]. Group 3: Strategic Importance - The construction of "Dream" breaks the long-standing foreign monopoly in the deep-sea drilling vessel sector, positioning China as a leader in this field [5][6]. - The vessel's capabilities allow China to independently organize ocean drilling expeditions, transitioning from a participant to a leader in global ocean exploration [7]. - "Dream" is expected to significantly contribute to the understanding of Earth's internal structure and support global scientific endeavors to explore the unknown [7].
