Abstract

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 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.
