| Research Abstract |
The objects of this study were to evaluate the influence of submarine groundwater discharge (SGD) to the habitat environments of coral reefs, and to estimate nutrients load through SGD in coastal area in southern part of Okinawa Main Island. As a result, the nitrate load through SGD which were estimated by field observation and numerical simulation were 84.4kg/day～96.0kg/day in south east coast area, and 58.9 kg/day in west coast area. The results suggest that the SGD have influenced to the habitat environments of coral reefs in this coastal area.
