Ecology: Carbon Cycling
Can we capture more methane to be used effectively?
• Methane is produced from organic matter in anaerobic conditions by methanogenic archaeans and some diffuses into the atmosphere or accumulates in the ground.
• Methane is oxidized to carbon dioxide and water in the atmosphere.
• Peat forms when organic matter is not fully decomposed because of acidic and/or anaerobic conditions in waterlogged soils.
• Partially decomposed organic matter from past geological eras was converted either into coal or into oil and gas that accumulate in porous rocks.
• Animals such as reef-building corals and mollusca have hard parts that are composed of calcium carbonate and can become fossilized in limestone.
• Application: Estimation of carbon fluxes due to processes in the carbon cycle.
Carbon fluxes should be measured in gigatonnes.
• Application: Analysis of data from air monitoring stations to explain annual fluctuations.
