Leond Aizikovich Rukhovets, professor, Doctor of Sciences, he started to work in Leningradean Branch of Steklov Mathematical Institute, USSR Academy of Sciences in 1959. In this Branch he worked during the period 1959-1965. The next periods 1965-1975,1975-1985 he was the scientific researcher in Lenigradean Branch of Central Institute of Mathematics and Economics, USSR Academy of Scieces and Leningradean Institute of Social and Economical Problems, USSR Academy of Sciences correspondingly. During period 1986-1990 he worked in Limnological Institute, USSR Academy of Sciences at Leningrad. He received his doctor's degree in computational mathematics in 1970 from Leningradean Branch of Steklov Mathematical Institute of USSR Academy of Sciences. His dissertation was devoted to study the finite element method (FEM) for solution boudary value problems for differential equations with partial derivatives. Later the interest of his investigations was focused upon the computational geophysicalhydrodynamics, models of large lakes circulation, ecosystem models and its implementation in conservation and managemtnt of water resources. In 1990 he was awarded a Doctor of Sciences degree in physics and mathematics. Leonid Rukhovets is the author more than 130 scientific articles and eight books. He took part in conferences and was visiting scientist in Oceanology Institute of Poland Academy of Sciences (Poland,1989), in Finland (1995, 1996, 1998, 2003,2006), USA(1999), Danmark (1999), Estonia (2006), Canada (2007). From 1998 to present Leonid Rukhovets is working in Institute for Economics and Mathematics at St.Petersburg, RAS as Director of Instirute and a head of the laboratory of mathematical modelling. He is a professor of State Marine Technical University. Nikolai Nikolaevich Filatov , professor, Ph.D., He start work in limnilogical institute, Academy of Sc. and received his doctorate in geography in 1975 from the State University in Leningrad , where he conducted investigations of currents in Large Lakes. He are working in the Institute for Lakes Research of the Russian (then USSR) Academy of Sciences from 1971-1988 y., where his research interests become focused upon limnological, hydrophisics , and remote sensing. He was awarded a D.Sc. degree in 1991. He has authored more than 300 scientific articles and 10 books. Now he is working in Nortern Water Problems Instittute as Director of the institute and head of laboratory of Geographical. His research activities continue to be directed toward the remote sensing, limnology and phisics of inland waters. He was visiting scientist in Canada (1979,1990), Austria, in International institute for Applied system analysis(1977), Finland (1983,1990,1993,1995-2002), Sweden (1992,1996, 2001, 2004).He is proffesor of State Pedagogical university (Petrozavodsk), President of Karelian Geographical society.
