gsw_t_from_pt0_ice: 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

Value

in-situ temperature (ITS-90) [ 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).
