| Zusammenfassung |
| The 2004 Gibbs thermodynamic potential function of naturally abundant water
ice is based on much more experimental data than its predecessors, is
therefore significantly more accurate and reliable, and for the first time
describes the entire temperature and pressure range of existence of this ice
phase. It is expressed in the ITS-90 temperature scale and is consistent
with the current scientific pure water standard, IAPWS-95, and the 2003
Gibbs potential of seawater. The combination of these formulations provides
sublimation pressures, freezing points, and sea ice properties covering the
parameter ranges of oceanographic interest. This paper provides source code
examples in Visual Basic, Fortran and C++ for the computation of the Gibbs
function of ice and its partial derivatives. It reports the most important
related thermodynamic equations for ice and sea ice properties. |
