Abstract:

   In this work the new kind of the equation of state expressing the density of sea water through independent and in situ measurable parameters: temperature, pressure and sound velocity, is justified theoretically and implemented in practice. The novelty of the approach is that the use of sound velocity as one of the arguments makes it possible measuring of the density of sea water without measurements of salinity. The developed equation reproduces the density of sea water with a high accuracy in a wide range of parameters.

Keywords: equation of state, sea water, density, speed of sound, TEOS-IO.
