Since 2003 monitoring of sea water transparency has been conducted by measuring the Sekki disk depth at the Island of Zmiinyi (Black Sea) by specialists of the Odessa National Mechnikov University (ONU). The collected material (more than 1500 measurements) allowed to perform analysis of transparency values in 2003-2007 in comparison with previous periods of observations. According to data of the Marine Hydrophysical Institute, in the Danube mouth area of the Black sea, where the Zmiinyi Island is located, in 1925-1997 a progressive decreasing tendency of water transparency was observed from year to year.
