近30年来海洋学最重要的突破之一是发现铁(Fe)作为一种微量营养素控制着生物生产，我们对铁和海洋中营养物质生物地球化学动力学的理解有了显著的进步。在这篇综述中，我们回顾了亚北极太平洋自然铁供应过程和营养动态及其对生物生产的影响的先前和最新知识。尽管大气尘埃被认为是影响亚北极太平洋生物生产的最重要的铁来源，但也发现了其他海洋来源的铁。我们对亚北极太平洋高营养低叶绿素(HNLC)水域的生物反应提出了一个连贯的解释，该解释结合了大气铁供应和海洋铁供应的知识。最后，我们提出了亚北极太平洋铁海洋学研究的未来方向，并总结了到目前为止确定的不确定问题。
One of the most important breakthroughs in oceanography in the last 30 years was the discovery that iron (Fe) controls biological production as a micronutrient, and our understanding of Fe and nutrient biogeochemical dynamics in the ocean has significantly advanced. In this review, we looked back both previous and updated knowledge of the natural Fe supply processes and nutrient dynamics in the subarctic Pacific and its impact on biological production. Although atmospheric dust has been considered to be the most important source of Fe affecting biological production in the subarctic Pacific, other oceanic sources of Fe have been discovered. We propose a coherent explanation for the biological response in subarctic Pacific high nutrient low chlorophyll (HNLC) waters that incorporates knowledge of both the atmospheric Fe supplies and the oceanic Fe supplies. Finally, we extract future directions for Fe oceanographic research in the subarctic Pacific and summarize the uncertain issues identified thus far.
