Further research is needed to study the entire biological succession after iron fertilization. The evaluation of potential environmental side effects, including oxygen reduction and production of greenhouse gases, requires further research. The development of ocean iron fertilization as a practical means to remove carbon dioxide from the atmosphere and mitigate climate change requires further research.
