This is a Python re-write of the CSIRO seawater toolbox (SEAWATER-3.3) for calculating the properties of sea water. The package uses the formulas from Unesco’s joint panel on oceanographic tables and standards, UNESCO 1981 and UNESCO 1983 (EOS-80).
The EOS-80 library is considered now obsolete; it is provided here for compatibility with old scripts, and to allow a smooth transition to the new TEOS-10.
