  • 平原语言概述哈达尔沟(深度> 6,000米)是我们星球上最偏远,探索最少的地方,具有低温,高压,食物有限和地质活动频繁的特点。了解海洋生物的有机物质来源是了解海洋碳循环和战壕中生物适应的关键。我们报告了西太平洋三个战壕中的第一个14C结果,包括最深的海沟Mariana,这表明片脚类动物的有机物主要来自地表水。荒地动物群和地表水中有机物之间的这种紧密联系指出,人为污染可以通过食物链迅速到达最深的海沟。此外,炸弹14C测年方法可以应用于鸭片片脚类动物,从而表明低组织更新率和意外长寿命,这可能是适应贫困和恶劣环境的结果。
  • Plain Language Hadal trenches (depth >6,000 m) are the remotest and the least‐explored places on our planet, with characteristics of low temperatures, high pressure, limited food and frequent geological activity. Knowing the source of organic matter for hadal life is key in understanding the ocean carbon cycle and the biological adaptation in trenches. We report the first 14C results of hadal amphipods from three trenches in the West Pacific, including the deepest ocean trench, Mariana, which indicates that the organic matter for amphipods is mostly from the surface water. This tight linkage between the organic matter within the hadal fauna and in surface water points out that the anthropogenic pollution can reach the deepest ocean trench rapidly via the food chain. Moreover, the bomb 14C dating method can be applied to hadal amphipods, thereby suggesting a low tissue turnover rate and an unexpectedly long lifetime, which might be a result of an adaptation to the impoverished and harsh environment.
