Abstract
In order for a coral reef to be a CO2 absorbing source, a condition would have to be satisfied that, with respect to production of organic carbon through photosynthesis, a total production by coral reef organism association is large, and the ratio of the total production to a total consumption is more than one. A requirement that the ratio of inorganic carbon production through calcification be 1.5 or more must also be met. Measurements have been carried out at coral fields off the Ishigaki Island by the Geological Research Center. The measurement results revealed that production is high for both of organic carbon and inorganic carbon, surplus organic carbon is produced, and CO2 is absorbed into the coral reefs. It was also found by measuring the stable isotope ratio of nitrogen in coral reef organisms that nitrogen required for the production in the coral reefs is supplied from the atmosphere through nitrogen fixation. The paper adds a description that CaCO3 deposition in the coral reefs has peaked in 5000 years to 6000 years ago, and it is in a ceiling-hit condition now. 25 refs., 3 figs.
