近期,Tagliabue等在Nature上发文“The integral role of iron in ocean biogeochemistry”阐述了铁在海洋生物地球化学循环中的不可或缺的作用。该文系Nature综述,读后感觉到了自己知识上的匮乏。
知识上的匮乏会导致认知上的偏差。

The micronutrient iron is now recognized to be important in regulating the magnitude and dynamics of ocean primary productivity, making it an integral component of the ocean’s biogeochemical cycles. In this Review, we discuss how a recent increase in observational data for this trace metal has challenged the prevailing view of the ocean iron cycle. Instead of focusing on dust as the major iron source and emphasizing iron’s tight biogeochemical coupling to major nutrients, a more complex and diverse picture of the sources of iron, its cycling processes and intricate linkages with the ocean carbon and nitrogen cycles has emerged.
