A system (set) of standard reference exergies of chemical 
elements, called the Ocean-2 system, is presented. It includes refined 
exergies of nine atmospheric elements and 79 elements dissolved in 
the oceanic water with I>S = 35‰ pH 7.905, a standard temperature 
of 298.15 K, and a standard pressure of 101.325 kPa. These exergies were 
calculated in a simplified chemical approximation with the use of a unique 
representative species for each element, selected by thermodynamic sifting. 
The suggestion has been made that the Ocean-2 system of standard reference 
exergies is close to the lithospheric system.
