在海底捡“特产” 给地球做CT
Xin Lang Cai Jing· 2026-02-21 18:17
●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 ...

北冰洋关键区域内潮动力学研究获进展
Zhong Guo Zi Ran Zi Yuan Bao· 2026-01-20 03:55
中国极地研究中心自然资源部极地科学重点实验室极地气—冰—海相互作用研究团队一项对北冰洋 巴伦支海—喀拉海区域内潮动力学的研究,打破了学界对喀拉海峡附近海洋动力过程的传统认知,为深 入理解北极潮汐混合机制提供了全新视角。该研究成果近日在国际期刊发表。 巴伦支海—喀拉海区域是北极海冰变化的敏感核心区域,也是北冰洋大西洋化的前哨区域,同时还 是影响东亚乃至北半球气候变化的关键区域之一。其中,喀拉海峡不仅是该区域海冰输运与能量传递的 核心枢纽,更是北极东北航道的重要节点,具有突出的科研价值与意义。喀拉海峡由于地形复杂且潮汐 活动强盛,成为海洋内波的活跃区域。海洋内波可通过驱动海水垂向混合,调控海洋热收支平衡,进而 影响海冰变化,还能通过改变海—气热量交换过程作用于大气环流,最终对欧亚中高纬度的天气与气候 产生影响。此外,内潮分裂所激发的大振幅内孤立波,还可能对北极航道的通航环境构成潜在威胁。当 前,针对喀拉海峡内波的研究仍较为匮乏,这制约了北极航道的安全规划与运营。 该团队的研究结果显示,该海区中瓦伊加奇岛的陆坡区域是另一处重要的内潮生成源,且其能量强 度甚至超过了海峡中部区域。背景环流将内潮限制在瓦伊加奇岛陆坡外侧 ...
