新研究发现,深海采矿试验导致海底无脊椎动物下降37%,物种多样性丧失32%。 A deep-sea mining test caused a 37% drop in seafloor invertebrates and 32% loss in species diversity, new study finds.

太平洋克拉里昂-克利珀顿区一项五年研究发现,在受深海采矿机器直接影响的地区,海底无脊椎动物减少了37%,物种多样性减少了32%。 A five-year study in the Pacific’s Clarion-Clipperton Zone found a 37% decline in seafloor invertebrates and a 32% drop in species diversity in areas directly impacted by a deep-sea mining machine. 来自哥德堡大学自然历史博物馆和国家海洋学中心的研究人员收集了4 350只动物,确定了788种物种,其中许多是以前未知的物种。 Researchers from the Natural History Museum, University of Gothenburg, and National Oceanography Centre collected 4,350 animals, identifying 788 species, many previously unknown. 虽然沉积物羽流没有减少动物的丰量,但它们增加了某些物种的主导地位,表明生态系统受到干扰。 While sediment plumes did not reduce animal abundance, they increased dominance of certain species, indicating ecosystem disruption. 这些迄今最全面的调查结果为国际海底管理局提供了重要数据,用以指导深海采矿政策,并强调需要在保护区扩大调查。 The findings, the most comprehensive to date, provide critical data for the International Seabed Authority to guide deep-sea mining policies and underscore the need for expanded surveys in protected zones.
