Ocean fertilization

Ocean fertilization is a geoengineering technique aimed at enhancing the ocean's capacity to absorb carbon dioxide (CO2) from the atmosphere. This process involves adding nutrients, such as iron, nitrogen, or phosphorus, to ocean waters to stimulate the growth of phytoplankton, which are microscopic plants that form the base of the marine food web. Phytoplankton undergo photosynthesis, absorbing CO2 and producing oxygen in the process.
