The Earth's oceans contain a large amount of CO2 in the form of bicarbonate and carbonate ions â much more than the amount in the atmosphere. The bicarbonate is produced in reactions between rock, water, and carbon dioxide.
The Carbon Cycle. Where is most of the Earth's carbon located and in what form? Most of the world's carbon is found in the ocean as either carbon dioxide or calcium carbonate. Shells of most sea creatures are composed of calcium carbonate. Once these creatures die their shells turn into limestone and as limestone erodes the carbon is released into the atmosphere or bodies of water.
