●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"。 让我们一起登上这艘船，看看太平洋几千米深处的独特风景。 海底"黑土豆" 记录3000万年深海环境变迁 看清海底50公里下"冷热交锋" 除了捡"土豆"，这次科考的硬核成果之一，是给地球做了一次深层"体检"。科考团队将一套自主研发的 电磁测量设备投放到7663米的深海，创下目前国内最深的电磁剖面测量纪录。 为什么要费尽周折把设备放到那么深的地方？ 在这次航行中，最引人注目的首先是"探险队员"的升级。以往的深海调查，往往依赖单一设备单打独 斗。这一次，中国科学家在太平洋深水区上演了一场精彩的"机甲配合战"。 这是国内首次让 ...

Core Insights - The "Marine Geological No. 6" research vessel successfully returned from a 95-day expedition in the Pacific, uncovering significant scientific findings, including polymetallic nodules that have been dormant for 30 million years [1][3]. Group 1: Research Achievements - The expedition utilized a combination of self-developed deep-sea remotely operated vehicles and autonomous underwater robots for high-precision sampling and data collection, marking a significant advancement in deep-sea exploration technology [3][4]. - The polymetallic nodules discovered are rich in metals such as cobalt, nickel, copper, and manganese, which are crucial for enhancing mineral resource security. These nodules grow extremely slowly, taking millions of years to form, and provide insights into historical oceanic environmental changes [4][5]. - The research team conducted a deep-sea electromagnetic profile measurement, achieving a record depth of 7,663 meters, which allowed for a detailed understanding of the Earth's internal structure and dynamics [5][7]. Group 2: Implications for Future Research - The findings from the expedition will support future ocean drilling projects, with plans for the advanced "Dream" drilling vessel to conduct exploratory drilling in the South China Sea [8][9]. - The research also highlights the potential of deep-sea biological resources, such as unique enzymes and compounds from deep-sea organisms, which could have applications in medicine and biotechnology [8]. - The ongoing exploration aims to address fundamental questions about life origins, climate evolution, and the role of the ocean in global material cycles, indicating a continuous commitment to deep-sea research [9].

Core Points - The 15th National Games and the 12th National Paralympic Games, along with the 9th Special Olympics, held a torch collection ceremony in Guangzhou, showcasing the integration of marine culture and technological innovation in the Greater Bay Area [1] - The torch was sourced from 1,522 meters deep in the South China Sea, marking a historical breakthrough in global large-scale comprehensive sports events [1] - The collection utilized a deep-sea remotely operated vehicle (ROV) equipped with a combustible ice collection and ignition device, demonstrating China's deep-sea technological capabilities [1] Technological Innovation - The torch collection process involved advanced technology, including remote ignition of combustible ice at ultra-deep sea levels, which was recorded using ultra-high-definition equipment [1] - This innovation reflects the requirements for a "simple, safe, and exciting" event, embodying the Olympic spirit and the theme of technological collaboration and regional integration [1] Cultural Significance - The event highlights the unique marine culture of the Greater Bay Area and the scientific and technological strength of the region [1] - The successful execution of the torch collection task is seen as a vivid representation of the event's principles of "green, shared, open, and clean" [1]
