Molecular oxygen is the substance most extensively monitored in scientific and routine investigations of aquatic ecosystems. Oxygen distributions in stratified lakes and departures from atmospheric equilibrium concentrations provide more information on lake characteristics and for water management than any other chemical parameter . Accordingly, the most common application of POS in field ecology is the measurement of dissolved oxygen concentrations along vertical or horizontal transects of aquatic systems. The situation is reflected by the abundance of commercially available in situ oxygen probes (e.g., Delta Scientific, Electronic Instruments Limited, International Biophysics Corporation, Kahlsico International Corporation, Orbisphere Laboratories, Wissenschaftlich-Technische Werkstätten, Yellow Springs Instruments). These sensors incorporate macrocathodes and are commonly equipped with a simple battery-operated stirring device, and most instructions leave no doubt about the ease of the method.
