Conservative Temperature at Maximum Density


Conservative Temperature at Maximum Density


gsw_CT_maxdensity(SA, p)



Absolute Salinity [ g/kg ]


sea pressure [dbar], i.e. absolute pressure [dbar] minus 10.1325 dbar


Conservative Temperature [ degC ]

Implementation Note

This R function uses a wrapper to a C function contained within the GSW-C system as updated 2021-12-28 at 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 website. Therefore, in the interests of making GSW-R be self-contained, a copy was downloaded from on 2022-05-25, the .mat file was stored in the developer/create_data directory of, and then the dataset used in GSW-R was created based on that .mat file.

Please consult to learn more about the various TEOS-10 software systems.
