Latent Heat of Melting
gsw_latentheat_melting(SA, p)
SA: Absolute Salinity [ g/kg ]. The valid range for most gsw functions is 0 to 42 g/kg.p: sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbarlatent heat of freezing [ J/kg ]
This R function uses a wrapper to a C function contained within the GSW-C system as updated 2022-10-11 at https://github.com/TEOS-10/GSW-C with git commit 657216dd4f5ea079b5f0e021a4163e2d26893371.
The 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 of the mat file 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 2022-05-25, 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.
