This project provides a small C++11 library for calculating the chemical composition of seawater given a practical salinity.

The composition is based on the six most important (by reference salinity) materials dissolved in Standard Seawater, according to F. J. Millero et al., Deep Sea Research Part I: Oceanographic Research Papers 55.1 (2008), pp. 50-72.

The C++11 library consists of a simple set of C++ classes that represent chemical elements, element mass fractions, numbers of atoms, molecules, and mixtures. These classes can be used for creating a seawater material for detector simulations with e.g. Geant4.

This project also provides a Python interface to the C++ library.

Install instructions and other details are given in the project's docs.
