Hydrochemical conditions in the south-eastern part of the Baltic Sea in 2018

In this research the hydrochemical data obtained in the coastal waters of the Baltic Sea in the Sambian Peninsula region in June-August 2018 is analyzed. The concentration of dissolved oxygen, phosphates and silicates in the surface layer corresponds to typical values for a given time and region. Hydrogen sulphide is found at a depth of 90 m and more. An assumption of the reasons for the fast development of anaerobic conditions in this area is made.
