The densities of surface waters from the Caspian Sea have been determined at 5, 15, 25, and 35°C. The composition of the waters has been related to the chlorinity and relative conductivity. The densities have been used to determine an equation of state for Caspian seawaters at one atmosphere. The densities of Caspian seawaters are ∼560 × 10-6 g cm-3 higher than standard seawater at the same salinity due to the higher concentrations of Mg2+, Ca2+, and SO42-. Calculations of the density of Caspian seawaters at 25°C from density data on the components of the waters agree with the measured values to ±28 × 10-6 g cm-3.
