gsw (version 1.0-5)

gsw_CT_from_rho: 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

Value

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