gsw_SR_from_SP {gsw} | R Documentation

## Calculate Reference Salinity from Practical Salinity

### Description

Calculate Reference Salinity from Practical Salinity

### Usage

    gsw_SR_from_SP(SP)

### Arguments

`SP` | Practical Salinity (PSS-78) [ unitless ]

### 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).
