Carbon dioxide in Earth's atmosphere atmosphere, oceans, soil, rocks, and volcanism. Both carbon cycles are intrinsically interconnected and atmospheric gaseous carbon dioxide facilitates the carbon cycle. Natural sources of atmospheric carbon dioxide include volcanic outgassing, the combustion of organic matter, wildfires and the respiration processes of living aerobic organisms. Man-made sources of carbon dioxide include the burning of fossil fuels for heating, power generation and transport, as well as some industrial processes such as cement making. It is also produced by various microorganisms from fermentation and cellular respiration. Plants, algae and cyanobacteria convert carbon dioxide to carbohydrates by a process called photosynthesis. They gain the
Ocean storage of carbon dioxide water column. The carbon dioxide is usually injected at 1000 m depth to reduce carbon dioxide bubble escape. As injected carbon dioxide bubbles rise, dispersal increases up the water column. Large dispersal areas and low concentrations of carbon dioxide significantly decrease any significant changes in local pH and resulting effects on marine ecosystems. Wickett et al. used measurements in natural pH fluctuations from atmospheric carbon dioxide to suggest that dilute carbon dioxide injection at 0.37 GTC/ yr would have a negligible effect on ocean pH. Dilute ocean injection requires little infrastructure in comparison to other forms of ocean injection. The
