The position and seasonal fluctuations of the depth of the maximum water salinity gradient in the Black Sea in the upper 150 m layer (halocline), which is interpreted as the upper boundary of the hydrogen sulfide layer in the sea, were estimated based on the analysis of climatic data of the vertical distribution of salinity for the period 1903—1982. Seasonal maps of the depth of this boundary in the water area of the sea were constructed, and extrema (axes of maximum and minimum) were identified
