This is a convenience, for processing data that often have this condition. For example, a CTD profile is likely to have many values for SP, t, and p, but just a single value for each of longitude and latitude.

WebSeveral free energy functions may be formulated based on system criteria. Free energy functions are Legendre transforms of the internal energy. The Gibbs free energy is given by G = H − TS, where H is the enthalpy, T is the absolute temperature, and S is the entropy. H = U + pV, where U is the internal energy, p is the pressure, and V is the ...
