Abstract

The density measurements by Millero, Gonzalez and Ward (1976, Journal of Marine Research,34, 61-93) and Poisson, Brunet and Brun-Cottan (1980, Deep-Sea Research, 27, 1013-1028), from 0 to 40°C and 0.5 to 43 salinity, have been used to determine a new 1-atm equation of state for seawater. The equation is of the form (t°C; S; ρ{variant} kg m^-3)ρ=ρ₀+AS+BS^{3 2}+CS, where A=8.24493×10^-1-4.0899×10^-3t+7.6438×10^-5t²-8.2467×10^-7t³+5.3875×10^-9t⁴B=-5.72466×10^-3+1.0227×10^-4t-1.6546×10^-6t²C=4.8314×10^-4 and ρ{variant}₀ is the density of water (Bigg, 1967, British Journal of Applied Physics, 8, 521-537). ρ₀=999.842594+6.793952×10^-2t-9.095290×^-3t²+1.001685×10^-4t³-1.120083×10^-6t⁴+6.536336×10^-9t⁵. The standard error of the equation is 3.6 × 10^-3 kg m^-3. This equation will become the new 1-atm equation of state of seawater that has been suggested for use by the UNESCO (United Nations Educational, Scientific and Cultural Organization) joint panel on oceanographic tables and standards.
