Results of the comprehensive studies of hydrological and chemical structure of the Middle and Northern Caspian Sea carried out aboard r/v “Issledovatel Kaspiya” in September 2022 are presented. It is shown, despite the continuing decrease in sea level, there is no aeration of the deep layers, the hydrogen sulfide layer persists with a tendency to increase the concentration of hydrogen sulfide in the bottom layer. There is an increase of the oxygen minimum zone. The changes of the Caspian Sea ecosystem have led to a weakening of the removal of nutrients from the photic layer into the bottom layers and, as a consequence, a decrease in the concentration of silicon in the bottom layer. The results obtained will allow to evaluate the trends of ongoing changes.
