在我们的星球上进行的一些最大规模的科学操作实验已经使海洋表面的大片区域富含铁。这些铁富集实验的表面海洋特征覆盖了高达1000公里(2)的区域，并且从太空中很明显。自20世纪90年代初以来，在三个特定的海洋区域——南大洋、太平洋的赤道和亚北极地区——进行了12项这样的多学科研究，这些区域的植物营养成分常年较高（称为高营养低叶绿素，或HNLC）。此外，还在北大西洋进行了磷铁联合富集实验。总之，这些研究代表了一套独特的物理、化学、光学、生物和生态数据。生物和化学海洋学数据管理处（BCO_DMO; http://osprey.bco-dmo.org/program.cfm?flag=viewp&id=10&sortby=program）的一个开放存取关系数据库捕获了这些丰富的数据集。它是海洋研究科学委员会第131工作组（就地铁富集的遗产：数据汇编和建模；http://www.scor-int.org/Working_Groups/wg131.htm）的产品。本文的目的是让更广泛的社区了解这个资源。它还介绍了该数据库的优点，并提供了利用该数据库探索海洋学中新出现的主题的实例，例如生态系统过程和生物地球化学循环之间的联系；海洋地球工程的可行性及诸多副作用以及如何理解中尺度物理、化学和生物过程之间的耦合可以为新兴的亚中尺度生物地球化学领域提供信息。
Some of the largest scientific manipulation experiments conducted on our planet have enriched broad swaths of the surface ocean with iron. Surface ocean signatures of these iron enrichment experiments have covered areas up to > 1,000 km(2) and have been conspicuous from space. Twelve of these multidisciplinary studies have been conducted since the early 1990s in three specific ocean regions-the Southern Ocean, and equatorial and sub-Arctic areas of the Pacific Ocean-where plant nutrients are perennially high (termed high nutrient low chlorophyll, or HNLC). In addition, a combined phosphorus and iron enrichment experiment was conducted in the oligotrophic North Atlantic Ocean. Together, these studies represent a unique set of physical, chemical, optical, biological, and ecological data. The richness of these data sets is captured in an open-access relational database at the Biological and Chemical Oceanography Data Management Office (BCO_DMO; http://osprey.bco-dmo.org/program.cfm?flag=viewp&id=10&sortby=program). It is a product of Working Group 131 (The Legacy of in situ Iron Enrichment: Data Compilation and Modeling; http://www.scor-int.org/Working_Groups/wg131.htm) of the Scientific Committee on Oceanic Research. The purpose of this article is to make the wider community aware of this resource. It also presents the merits and provides examples of the utility of this database for exploring emerging topics in oceanography, such as the links between ecosystem processes and biogeochemical cycles; the feasibility and many side effects of oceanic geoengineering; and how understanding the coupling among physical, chemical, and biological processes at the mesoscale can inform the emerging field of submesoscale biogeochemistry.
