On the Possibility to Assess the Ecological State of Aquatic Ecosystems Based on Entropy

A new method to assess the state of aquatic ecosystems by the ecosystem entropy variation using data on dissolved oxygen concentration and water temperature is discussed. The method is based on the thermodynamic state parameter which allows the uniform evaluation of the state of aquatic ecosystems regardless of their typological and regional features. The proposed method can be implemented in the automated way and in real time.
