gsw_CT_from_rho {gsw} | R Documentation

## Conservative Temperature from Density, Absolute Salinity and Pressure

### Description

Conservative Temperature from Density, Absolute Salinity and Pressure

### Usage

    gsw_CT_from_rho(rho, SA, p)

### Arguments

`rho` | seawater density [ kg/m^3 ]
`SA` | Absolute Salinity [ g/kg ]
`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). Consult http://www.teos-10.org to learn more about these software systems, their authorships, and the science behind it all.

### Value

A list containing two estimates of Conservative Temperature: `CT` and `CT_multiple`, each in [ degC ].
