Analysis of Supersaturated Air in Natural Waters and Reservoirs

Abstract
Supersaturation of air or other gases in water can be caused by a temperature increase, air or gas injection by pressurized pumping, or turbulent injection by falling water which traps air when spills are allowed by hydroelectric projects. Evaluation of this problem requires both an understanding of the physics of the situation and practical knowledge of a number of alternative techniques for analysis. These range from complex, exacting procedures commonly used in the biomedical analytical laboratory to simple, portable methods well suited to use in the field or continuous monitoring. The authors have reviewed and refined several of these methods, have developed others, and have compared relevant techniques in the field and laboratory.
