Specialization

E.E. Sovga's scientific interests are connected with the key problems of the condition and evolution of the Black Sea ecosystems, and concern geochemical processes taking place both in the water column of the Black Sea and in the sea–atmosphere and sea–bottom sediments interfaces, as well as the environmental problems of the Black Sea region associated with them.
The field of E.E. Sovga research includes not only the deep-sea area with its unique hydrogen sulphide zone but also the shallow water one in the North-West Sea, and the ecologically vulnerable sea–land boundary zones undergone an intensive anthropogenic load, as well.

Main Directions of Scientific Activity

Features of geochemical processes taking place in the deep-sea hydrogen sulphide zone of the Black Sea
Based on the experimental and theoretical researches, a geochemical transformation of inorganic forms of sulfur in the hydrogen sulphide zone of the Black Sea was investigated and for the first time the nature of a deep-sea turbid water layer in the Black Sea was found out. The features of a geochemical behaviour of some heavy metals under conditions of the hydrogen sulphide zone were investigated and chemical forms of their presence in water column, accounting the state of carbonate system components, as well as in the water–bottom sediment boundary zone were defined.
E.E. Sovga in the co-authorship with other scientists studied the ecologically sensitive zones at the land–sea interface and divided the Black Sea coastal territories of Ukraine into regions according to their economic activities.

Development of methods for mathematical modeling of the Black Sea shelf and pelagial ecosystems

E.E. Sovga together with the academician V.I. Belyaev, the world known oceanologist, developed a mathematical model of the hydrogen sulphide zone ecosystem in the Black Sea. Using this model, scenarios for the response of the hydrogen sulphide zone ecosystem to both natural endogenous methane intrusions from the Black Sea bottom and probable emergencies at the deep gas main that is under construction in the East Black Sea were designed. Predicted estimates of conditions for hypoxic and anoxic zones appearance on the Northwest shelf of the Black Sea were obtained on the base of the advanced version of this model.

Scientific and Organization Activity

1987–1992 – the Scientific Secretary of the World Ocean Problems Committee, the Presidium of the National Academy of Sciences of Ukraine
1992 – 1997, the Scientific Secretary of the Crimean Branch of the National Academy of Sciences of Ukraine
2002–now – the Scientific Secretary of the Specialized Scientific Council D.50.158.01, the Marine Hydrophysical Institute (specialty 11.00.08. oceanology (geographical sciences))
The associate editor of "Marine Ecological Journal" and collections of proceedings of the Marine Hydrophysical Institute of the National Academy of Sciences of Ukraine: "Monitoring Systems of the Environment" and "Ecological Safety of the Coastal and Shelf Zones and Complex Use of the Shelf Resources"
E.E.Sovga pays great attention to educational activity and works with youth. For already three years she gives lectures at the Geographical Department in the Black Sea Branch of the Moscow State University.
Now she is a supervisor of studies for a post-graduate student and a competitor.
In 2006 E.E. Sovga was confirmed by the Presidium of the National Academy of Sciences of Ukraine as a supervisor of the Searching Theme “Research of Optimal Integration Processes Providing Ecologically Safe Development of the Coastal Regions of Ukraine" (code “Integration") for the period from 2006 till 2010.
