gsw_latentheat_melting: Latent Heat of Melting

In gsw: Gibbs Sea Water Functions

Latent Heat of Melting

Description

Latent Heat of Melting

Usage

gsw_latentheat_melting(SA, p)

Arguments

SA	Absolute Salinity [ g/kg ]
p	sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar

Value

latent heat of freezing [ J/kg ]

Implementation Note

This R function uses a wrapper to a C function contained within the GSW-C system as updated 2021-12-28 at https://github.com/TEOS-10/GSW-C with git commit '98f0fd40dd9ceb0ba82c9d47ac750e935a7d0459'.

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.

Please consult http://www.teos-10.org to learn more about the various TEOS-10 software systems.
