Monsoonal distribution of phosphate within Tallo Estuary, South of Sulawesi

Phosphate is one indicator of water fertility and is needed to support the life of organisms, especially phytoplankton. The main source of phosphate in the waters naturally originates from the processes of decomposition, weathering or decomposition of plants and comes from the remains of dead organisms. Besides this phosphates in coastal areas are sourced from rivers that carry waste from land, so phosphates in the river mouth are larger than the surrounding waters. The purpose of this study was to describe the pattern of phosphate distribution in the West and East seasons in the Tallo estuary, Makassar using hydrodynamic and distribution models of pollutants. The results of this study indicate the pattern of spreading phosphate in the study site is strongly influenced by oceanographic conditions of the waters.
