Algorithms for computation of fundamental properties of seawater,
based on the practical salinity scale (PSS-78) and the international
equation of state for seawater (EOS-80), are compiled in the present
report for implementing and standardizing computer programs for oceanographic
data processing.
Sample FORTRAN subprograms and tables are given to illustrate usage
of the algorithms and to show the range of variation and limits of validity
of commonly used seawater properties within the oceanic ranges for
salinity, temperature and pressure. The algorithms cover the following:
conductivity to salinity conversion; salinity to conductivity conversion;
specific volume anomaly and density anomaly of seawater; pressure to depth
conversion; freezing point temperature of seawater; specific heat of seawater;
adiabatic lapse rate; potential temperature; sound speed in seawater.
