| Research Abstract |
To clarify calcification mechanism of hermatypic corals, a coral polyp model under more realistic and comprehensive assumptions on physical, chemical and physiological processes was developed. The mechanism of “light-enhanced calcification” phenomenon was clarified by the model study, and the simulation result of the model well reconstructed the phenomenon. Moreover to shed light on the “vital effect” of the skeletal records of carbon stable isotope ratio, a carbon isotope module for the coral polyp model was developed and it was incorporated into the polyp model. The modified model reconstructed reasonable values and clear seasonal variations of skeletal carbon isotope ratio.
