Estimation of volumes of aerobic and anaerobic waters in the Black Sea and of oxygen and hydrogen sulfide contained in them

Abstract

The mean depth of the upper boundary of the hydrogen sulfide zone (HSZ) in winter and summer is determined from the experimental data for the last 50 years. The estimates of aerobic and anaerobic water volumes and total oxygen and hydrogen sulfide in these seasons are derived from the data on the depth of the upper boundary of the HSZ position and more precise morphological parameters of the Black Sea. The aerobic and anaerobic water ratio is approximately 1: 10 in winter and 1: 9 in summer.
