Stunzhas, V. Mosharov, V. Radchenko] Different methods of measuring low oxygen concentrations were compared in July 2008 in the Black Sea: the conventional Winkler method, electrochemical sensors (membrane and membrane-free), and two modifications of photoluminescence sensors. The membrane-free sensor used in the Black Sea since 1999 and the domestic photoluminescence sensor showed the best results: agreement of data, possibility of fine oxygen distribution resolution, and absence of the oxygen and hydrogen sulfide coexistence layer. The latter has good technical characteristics: high oxygen sensitivity and complete inertness to hydrogen sulfide, possibility of calibration in a gaseous environment, and a relatively low time constant (5-6 s). An equation was suggested for dynamic correction of data in the testing mode, which eliminates hysteresis of data on probe descent and ascent to a significant degree. It was shown that the oxygen concentration above the hydrogen sulfide layer in the subreductive zone of the Black Sea did not exceed 0.02 μM. Pleiades Publishing, Ltd., 2013 Stunzhas P.
