Understanding tropical nutrient dynamics is essential for quantifying marine productivity. In tropical and subtropical oceans, however, the spatial and continuous observation of nutrients has been scarce. Coral skeleton could be a high resolution recorder of past nutrient dynamics in tropical and subtropical ocean with decades to millennia time scales. Nitrogen isotope of organic matter in the coral skeleton could vary with that of nitrogenous sources and be a potential to capture nitrogen isotope changes in marine nitrate. I have tried to demonstrate the possibility of coral nitrogen isotope as a new proxy and to apply to reconstruction of paleo-environment.

towards an understanding of controlling factors and

an application to paleo-environmental studies
