The seawater properties library routines are available in MATLAB, EES, and Excel VBA.
Correlations and data for the thermophysical properties of seawater are reviewed. For select functions such as transport and colligative properties, the temperature and salinity also implicitly define the pressure as: where P0 is taken as atmospheric pressure (0.101325 MPa) up to 100 °C and as the vapor pressure of seawater for higher temperatures.
