To comprehend the global seawater movement is important in clarifing the mechanism of global warming. Therefore, densities of seawater all over the oceans become important parameters. However, the precise data of density for seawater is not sufficient. As for TEOS-10 which is the exsisting thermodynamic equation of state for seawater, its uncertainty of density is 0.005 g/kg, but that of 0.001 g/kg is required. In this study, the measurement of density for seawater are conducted by hydrostatic weighting method. To obtain the precise data, the considerations on the procedure of measurement method are also reported.
