R: In situ Temperature from Potential Temperature at 0dbar

gsw_t_from_pt0_ice {gsw} | R Documentation

## In situ Temperature from Potential Temperature at 0dbar

### Description

In situ Temperature from Potential Temperature at 0dbar

### Usage

    gsw_t_from_pt0_ice(pt0_ice, p)

### Arguments

`pt0_ice` | potential temperature of ice (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).

### Value

in-situ temperature (ITS-90) [ degC ]
