人民日报记者 常钦 谈论深海时，你脑海中浮现的是什么？是幽暗无光的深渊，还是神秘未知的生物？ 对于自然资源部中国地质调查局广州海洋地质调查局"海洋地质六号"科考船来说，深海更像是一座 巨大的、待解读的"地质档案馆"。2025年12月1日，这艘科考船在历时95天、航行12673海里后，带着太 平洋深处的秘密，顺利返航靠泊广州南沙科考码头。此次科考取得多项重要科学成果，并正式对外发 布。 这次出远门，科学家们带回了令人惊叹的"特产"——沉睡海底3000万年的多金属结核，还"顺便"给 地球深部做了一次"CT扫描"。 这些"黑土豆"的学名叫多金属结核。在本次发布的成果视频中，它们静静地躺在水深4000—6500米 的深海盆地里，有球形、椭球形和碎屑状，形态各异。 别小看这些直径只有3到10厘米的石疙瘩。如果说陆地矿产是地球的馈赠，这些深海结核就是时间 的结晶。它们富含钴、镍、铜、锰等金属元素，是陆地资源的重要接替者，对提升矿产资源保障能力意 义重大。 广州海洋地质调查局研究员孙珍透露，这些结核的生长速度慢得惊人——每过100万年，它们才长 几毫米。视频画面里的一颗小小结核，可能形成于3000万年前。在漫长的生长过程中 ...

Core Viewpoint - The "Ocean Geological No. 6" research vessel has successfully completed its 15th deep-sea geological survey mission, with multiple scientific achievements officially released [1]. Group 1: Mission Overview - The 15th mission's second phase began on August 29 this year, lasting 95 days and covering a total distance of 12,673 nautical miles [3]. - The mission collected valuable data and samples, including deep-sea marine environmental data, seawater samples, seabed sediments, polymetallic nodules, and deep-sea biological samples [3]. Group 2: Technological Advancements - The mission marked the first use of domestically developed 6,000-meter deep-sea remotely operated vehicles and autonomous underwater robots in the Pacific deep-water area, achieving excellent application results [5]. - A significant achievement was the first electromagnetic profile measurement in the Pacific abyss, which provides high-quality electromagnetic observation data for future ocean drilling site selection [8]. Group 3: Future Plans - The "Ocean Geological No. 6" research vessel is scheduled to return to the Pacific in the first half of 2026 for more in-depth basic geological and environmental geological scientific investigations [7].

Core Insights - The "Marine Geological No. 6" research vessel has successfully completed the second phase of its 15th voyage, with multiple scientific achievements announced on December 10 [1] Group 1: Mission Overview - The second phase of the 15th voyage began on August 29 and lasted for 95 days, covering a total distance of 12,673 nautical miles [3] - The mission collected valuable data and samples, including deep-sea marine environment data, seawater samples, seabed sediments, polymetallic nodules, and deep-sea biological samples [3] Group 2: Technological Advancements - The mission marked the first use of domestically developed 6,000-meter deep-sea remotely operated vehicles and autonomous underwater robots in the Pacific deep-water area, achieving excellent application results [5] - Significant progress was made in the application of key technologies and equipment for deep-sea exploration [3] Group 3: Resource Discovery - A new resource-rich area of polymetallic nodules was discovered during the seabed mineral geological survey, expanding the resource space for seabed metal minerals [5] - Polymetallic nodules are primarily found at depths of 4,000 to 6,500 meters in deep-sea basins, with diameters ranging from 3 to 10 centimeters, composed mainly of iron-manganese oxides and hydroxides, and rich in key metal elements such as cobalt, nickel, copper, and manganese [7] Group 4: Future Plans - The "Marine Geological No. 6" research vessel is scheduled to return to the Pacific in the first half of 2026 for more in-depth basic geological and environmental geological scientific investigations [7]
