R: Potential temperature from Conservative Temperature

gsw_pt_from_CT {gsw} | R Documentation

## Potential temperature from Conservative Temperature

### Description

Potential temperature from Conservative Temperature

### Usage

    gsw_pt_from_CT(SA, CT)

### Arguments

`SA` | Absolute Salinity [ g/kg ]
`CT` | Conservative Temperature [ degC ]

### 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).
