Ocean storage of carbon dioxide ocean waters in order to increase carbon dioxide (CO2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects. Iron is a trace element in ocean and its presence is vital for photosynthesis in plants, and in particular phytoplanktons, as It has been shown that iron deficiency can limit ocean productivity and phytoplankton growth. For this reason, “iron hypothesis” was put forward by Martin in late 1980s where he suggested that changes in iron supply in iron-deficient ocean-waters can bloom plankton growth and have a significant effect on the concentrations of atmospheric carbon dioxide by altering rates of
Ocean storage of carbon dioxide on the dispersal to make the change in carbon dioxide concentration in the ocean low enough to not affect the marine biosphere significantly. The proposed method of injection is droplets of supercritical carbon dioxide mixed with seawater. Plumes can be engineered to dissolve at different rates based on the size, concentration, and rate of injection of the carbon dioxide/seawater droplets. For rising plumes which rely on dissolution to sequester carbon dioxide, a smaller droplet with a greater rate of injection is better because it leads to faster dissolution. Sinking plumes ideally form lakes of carbon dioxide on the ocean floor
