- Coastal eutrophication is a serious environmental problem in many parts of Indonesia coastal areas, including in coastal water of western coast of South Sulawesi (Spermonde Archipelago), where hundreds of hectare of coral reefs are situated. The nutrient enrichment of coastal waters off the Spermonde has mostly resulted from various activities that are related to the development of agriculture, aquaculture, and human settlement along the western coast. Rivers along the western coast play a significant role in mobilizing the nutrient to the Spermonde water. However, scientific investigation of the nutrient transport to the Spermonde coastal water is still lacking, and the effect of the eutrophication on the reef ecosystems are still not well studied. This study presents the results of comprehensive nutrient and eutrophication analysis as for understanding the characteristics of transport of dissolved inorganic nitrogen (NO3???N, NO2???N, NH3???N), PO4???P, silicate, suspended particulate matters, plankton biomass and structure, from three main rivers (Tallo, Maros, and Pangkep rivers) feeding to the coastal waters of the Spermonde. The characteristics of the nutrient input from the rivers will be compared to nutrient regime of the coastal ocean system, which results from upwelling event affecting the Spermonde coral reef at the edge of the continental shelf
