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 However, organisms are not only affected by the acidification of water in the presence of heightened carbon dioxide (carbon dioxide) levels. carbon dioxide itself interacts with the physiological function of individual organisms. These effects are more damaging than those associated with changes in pH of environment. When carbon dioxide enters organisms, through diffusion across tissue, it becomes internally accumulated which can then cause anesthesia and, depending on the concentration of carbon dioxide, death. The internal accumulation will also cause organisms to experience blood acidification. This weakens organisms' ability to uptake oxygen and consequently weakens their performances. This effect is more
