“unique lake”

Lake Sudobl area of 144 hectares located in the watershed of the Baltic and Black seas. The lake is unique in Eastern Europe not only due to the accumulation in it for 13 thousand years thirty meters sediment thickness of sapropels totaling more than 6 million m3. formed purely through the decay of biomass of the reservoir, but due to the high content of organic matter – 90-70% with different degree of transformation of organic matter.

13 thousand years ago in the lake began to accumulate sapropels with the participation of diatoms and plants of the pond with good aeration at the bottom of the pond. This is evidenced by the depth of the processes of biochemical decomposition and transformation of organic matter, the increase in the proportion of mineral substances and the accumulation of humic acids, causing the black coloration of sediments. Thus was formed the black sapropels.

Then when you change food and oxygen regime in a lake was formed due to the precipitation of blue-green algae dominated the processes of accumulation of dead organic biomass over its destruction, as evidenced by the low proportion of mineral substances (9-15%) and low content of humic acids. These processes led to the accumulation of sapropels green.

Finally, since the age of 3 thousand years ago when passing power of the lake to the stage with an intense oxygen regime in organic sediments begin to dominate Continue reading
