Carbon Dioxide Removal


Ocean Iron Fertilization

Ocean Iron Fertilization is the process of adding iron filings to seawater to stimulate the growth of phytoplankton that absorb atmospheric carbon dioxide. Ocean fertilization seeks to take advantage of the ocean's natural carbon pump, which uses carbon dioxide at the sea surface and incorporates the carbon, via photosynthesis, into biological tissues which can fall or be transported to the deep ocean. Certain areas of the ocean, including the Southern Ocean, have plentiful nutrients but lack iron, a key trace micronutrient that sea plants known as phytoplankton need to grow. So fertilization with iron has been proposed as a means of accelerating the carbon pump and increasing the size of the ocean carbon sink.
