Exploring Ocean Iron Solutions - ExOIS

Can ocean iron fertilization play a role in the solution to climate change? The ocean, which covers more than 70% of our planet, may be able to help. In a few key parts of the ocean, biological activity is limited by a lack of iron in seawater. Adding iron could, therefore, help spur growth of phytoplankton and increase both the uptake of carbon dioxide by the ocean and the amount that gets sequestered at depth. Science needs to lead the way, by providing the greatest possible insight into both the intended and unintended consequences, as well as the long-term effectiveness of adding iron to the ocean. The decisions we make today will shape the future of generations to come.
