海洋铁施肥（OIF）是否可以产生可验证的碳固存的问题往往是在施肥是否会导致增加颗粒输出。然而，模型研究表明，海洋碳储存与全球颗粒出口的关系很弱--相反，这取决于与矿化营养物池相关的碳的增加。这种增加的幅度取决于循环、化学计量比和气体交换。我们认为，这对在设计阶段必须考虑到的适当赞扬法语国家国际组织的努力提出了严重挑战。
The question of whether ocean iron fertilization (OIF) can yield verifiable carbon sequestration is often cast in terms of whether fertilization results in enhanced particle export. How- ever, model studies show that oceanic carbon storage is only weakly related to global particle export — depending instead on an increase in the carbon associated with the pool of remineralized nutrients. The magnitude of such an increase depends on circulation, stoichiometric ratios and gas exchange. We argue that this puts serious challenges before efforts to properly credit OIF that must be taken into account at the design stage.
