Usage

1

Arguments

SA

Absolute Salinity [ g/kg ]

t

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

p

sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar

Value

dilution coefficient [ (J/kg)(kg/g) ]

Implementation Note

This R function uses a wrapper to a C function contained within the GSW-C system as updated 2021-03-27 at https://github.com/TEOS-10/GSW-C with git commit 'f7bfebf44f686034636facb09852f1d5760c27f5'. In turn, that C function uses data from the library/gsw_data_v3_0.mat file provided in the GSW-Matlab source code, version 3.06-11. Unfortunately, this version is no longer displayed on the TEOS-10.org website. Therefore, in the interests of making GSW-R be self-contained, a copy was downloaded from http://www.teos-10.org/software/gsw_matlab_v3_06_11.zip on 2021-0706, the .mat file was stored in the developer/create_data directory of https://github.com/TEOS-10/GSW-R, and then the dataset used in GSW-R was created based on that .mat file. Please consult http://www.teos-10.org to learn more about the various TEOS-10 software systems.
