Calculate properties related to seaice melting in seawater
gsw_melting_seaice_into_seawater(SA, CT, p, w_seaice, SA_seaice, t_seaice)
SA |
Absolute Salinity [ g/kg ] |
CT |
Conservative Temperature [ degC ] |
p |
sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar |
w_seaice |
mass fraction (seaice) / (water + seaice) |
SA_seaice |
Absolute Salinity of seaice |
t_seaice |
temperature of seaice |
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).
