HYDROOPTICS FOR ECOLOGICAL MONITORING OF BLACK SEA

Abstract

The article describes a method for environmental monitoring of the Black Sea basin. The main indicator of environmental changes of water masses authors considers the variation of their transparency. In the currently used method for measuring the transparency of water environment based on definition ZW – depth visibility of white standard disc diameter of 300 millimeters, called the white disс, which falls into the aquatic environment from the deck of a surface ship. This method for measuring the transparency has significant drawbacks, among them – the ability to determine the transparency of the water only in the surface layer, dependent on weather conditions and the low accuracy of the measurement ZW value. To eliminate these drawbacks the authors propose another method of measuring the transparency of water environment based on the use of laser technologies.
