WebApr 26, 2024 · The outcomes of iron fertilization activities have not been disastrous as indicated in Article 1(4) and there is no prima facie evidence to confirm that it would lead to deleterious effects. Moreover, by supplying the deficient areas of the ocean with the necessary iron, the production of phytoplankton is likely to rise, which in turn raises ... WebSep 20, 2002 · Oceanic iron fertilization could increase phytoplankton primary productivity in iron-poor oceanic regions, enhancing the carbon flux to the deep sea and drawing excess CO 2 out of the atmosphere. It has been proposed as a way to sequester carbon and thus help to mitigate climate change. S. W.
