R: Calculate properties related to seaice melting in seawater

gsw_melting_seaice_into_seawater {gsw} | R Documentation

## Calculate properties related to seaice melting in seawater

### Description

Calculate properties related to seaice melting in seawater

### Usage

    gsw_melting_seaice_into_seawater(SA, CT, p, w_seaice, SA_seaice, t_seaice)

### Arguments

`SA` | Absolute Salinity [ g/kg ]
`CT` | Conservative Temperature [ degC ]
`p` | sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar
`w_seaice` | mass fraction (seaice) / (water + seaice)
`SA_seaice` | Absolute Salinity of seaice
`t_seaice` | temperature of seaice

### 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).

### Value

a list containing `SA_final` and `CT_final`.
