Potential Enthalpy of Ice (Polynomial version)
gsw_pot_enthalpy_from_pt_ice_poly(pt0_ice)
potential temperature of ice (ITS-90) [ degC ]
potential enthalpy [ J/kg ]
The present R function works with a wrapper to a C function contained within the GSW-C system (Version 3.05-4 dated 2017-08-07, available at https://github.com/TEOS-10/GSW-C, as git commit '5b4d959e54031f9e972f3e863f63e67fa4f5bfec'), which stems from the GSW-Fortran system (https://github.com/TEOS-10/GSW-Fortran) which in turn stems from the GSW-Matlab system (https://github.com/TEOS-10/GSW-Matlab).
