R: Chemical Potential of Water in Seawater

gsw_chem_potential_water_t_exact {gsw} | R Documentation

## Chemical Potential of Water in Seawater

### Description

Chemical Potential of Water in Seawater

### Usage

    gsw_chem_potential_water_t_exact(SA, t, p)

### Arguments

`SA` | Absolute Salinity [ g/kg ]
`t` | in-situ temperature (ITS-90) [ degC ]
`p` | sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar

### Details

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).
