Oceanic Iron Fertilization (OIF)

Oceanic Iron Fertilization (OIF) is a geoengineering technique that involves adding iron to certain parts of the ocean to stimulate the growth of phytoplankton, tiny marine plants that absorb carbon dioxide through photosynthesis. When these phytoplankton die, they sink to the ocean floor, effectively trapping carbon and helping to reduce greenhouse gases in the atmosphere. OIF mimics natural processes like dust storms that deposit iron onto the ocean surface, aiming to enhance natural carbon sequestration to combat climate change. However, it involves complex ecological considerations and is still under scientific study.
