Description Usage Arguments Details Value References Examples
This uses the C function named gsw_t_freezing_exact
, because the
C function named gsw_t_freezing
does not produce check values that
match the Matlab function called gsw_t_freezing
(see references
for those test values).
1 | gsw_t_freezing(SA, p, saturation_fraction = 1)
|
SA |
Absolute Salinity [ g/kg ] |
p |
sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar |
saturation_fraction |
fraction of air in water [unitless] |
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).
