The Banda Sea passes through the Indonesian Throughflow (ITF), and carries seawater mass from the Pacific Ocean toward the Indian Ocean. This influx affects the variations in oceanography parameters, and the monsoon winds aggravate the water complexities. The aim of this research, therefore is to determine seawater mass movements based on temperature and salinity distribution, expressed by the schematic model. These parameters are obtained from HYCOM and processed with ODV, followed by description, using a graphical software. The schematic model created based on the waters’ vertical temperature profile, and represented by one layer each. These include the water surface or 0m, which acted as the mixed layer, while the thermocline was observed at a depth of 150m. In addition, the final deep layer was featured at 500m. Particularly, the 0m model featured irregular salinity and temperature movement, possibly due to the influx of freshwater and monsoon winds. The seawater mass at 150m is reserved for a while in the Banda Sea before exiting into the Indian Ocean. Moreover, homogenous values were recorded, with relatively similar movements at 500m.
