SeaFreeze GUI: A User-Friendly Dive into Water and Ice Thermodynamics of Planetary Abysses.

We present here a new graphical user interface (GUI) for the SeaFreeze thermodynamic code. The SeaFreeze framework allows the computation of water and ice thermodynamics and elastic properties. While past water and ice thermodynamic representations have not been thermodynamically self-consistent, SeaFreeze accurately predicts all equilibrium thermodynamic properties (e.g. density, specific heat, bulk modulus, thermal expansivity, entropy, and enthalpy) based on the derivation of a single thermodynamic potential for each phase (here the Gibbs energy). It currently accurately predicts the thermodynamics of water and ice polymorphs (Ih, II, III, V and VI) up to 500K and 2300 MPa as well as their shear modulus and acoustic velocities. This permits for the examination of water-rich planetary hydrospheres structure, seismology and habitability, but also aids in many other scientific fields relying on water and ices thermodynamics, such as geochemistry and condensed matter physics.

SeaFreeze is currently available as a standalone code in Python and Matlab. To ease its use, a new SeaFreeze graphical user interface (GUI) has been created, working on MACs and PCs. This GUI i) allows the user to choose pressures and temperatures for the calculation of properties for ices Ih, II, III, V, and VI, liquid water and several aqueous electrolytes, ii) provides graphical displays of specified thermodynamic or elastic parameters, and iii) enables the flexible export of tables of properties under specified conditions. Furthermore, iv) the equilibrium boundaries between phases can be traced and exported.
