    　View Summary

    The objectives of this research are to estimate the acceptable daily phosphorus load (LD) for coral growth based on the correspondence between the total daily phosphate load (TDPL) and accumulated phosphorus in sea sediments. TDPL was estimated in conjunction with the results of field observations and integrated three-dimensional water cycle model. Based on the relationship between accumulated phosphorus and the number of juvenile corals in the study site, the threshold value of accumulated phosphorus was estimated to be 3.0 uM. A high positive correlation was observed between accumulated phosphorus and the total daily phosphorus load in the study site. The acceptable total daily phosphorus load for coral growth was estimated to be about 100 g-P/m3/day. These results confirm our hypothesis that terrestrial-derived phosphate is transported to the ocean through the water cycle and adsorbed on calcareous sediments, inhibiting coral growth.
