Candidate's Statement
My research of Khakasian salt lakes started in 1994 when I set up a biophysical field laboratory on Shira lake. From the standpoint of ecological biophysics few trophic levels, well expressed stratification (sea model?) make salt lakes an ideal object to develop mathematical methods of prognosticating and controlling ecosystem condition and in some cases they are a natural laboratory of would-be biospheric extreme conditions. Generalization of our own field data and development of a prognostic mathematical model of sulfur transport will make possible: 1) to develop a mathematical model of basic elements' turnover (С-N-S-P) in "surface- water mass - bottom" system; 2) to find out stability conditions of basic elements' cycles with respect to typical natural conditions (illumination conditions, anthropogenic run-off, flows at interfaces, etc.); 3) to correlate "blooming" of algae with sulfur cycle; 4) to establish relationship between stratification of the hydrogen sulfide zone and organic load on the lake; 5) to work out ecologically efficient scenarios of preserving the ecosystem of Shira and other Khakasian lakes. To organize international cooperation on Khakasian salt lakes I pursued holding the 8th ICSL in Siberia on Shira lake and it will take place 22-26 July 2002. I'm seeking for closer international cooperation with most interesting members of our «salt» community to introduce biophysical ideas into the cause of salt lake research.
