gsw_C_from_SP {gsw} | R Documentation |
Electrical conductivity (in mS/cm) from Practical Salinity. To convert the return value to conductivity ratio, divide by 42.9140 (the value of conductivity at S=35, T68=15, and p=0).
gsw_C_from_SP(SP, t, p)
SP |
Practical Salinity (PSS-78) [ unitless ] |
t |
in-situ temperature (ITS-90) [ degC ] |
p |
sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar |
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).
