Research interests:
Fedorov Yu.A. works at the Southern Federal University as the head of the Department of Physical Geography, Ecology and Nature Conservation. He is a well-known scientist in the field of oceanology, hydrochemistry and isotopic geochemistry of oceanic, marine, estuarine and freshwater ecosystems. Currently, he and his team of like-minded people are working in the field of fundamental and applied research aimed at understanding the laws of transformation of matter and energy in the geographical envelope; contact zones of the Earth's geospheres "atmosphere; hydrosphere; cryosphere ; lithosphere; biosphere", in the "river-sea" mixing zones and at the boundaries of the media interface.
Professor Fedorov Yu.A. achieved the following most significant scientific and practical results:
Developed a new scientific direction; isotope-chemical monitoring of oceanic, marine, estuarine and freshwater ecosystems.
- He put forward and theoretically substantiated the cryogenic hypothesis of the origin and evolution of the hydrosphere, which is based on the idea of the initial presence of water in the gas hydrate state on our planet.
- Proved that the formation of acid sulfate mine waters occurs when sulfates formed during bacterial and chemical oxidation of pyrite, groundwater, pore solutions and precipitation.
- He discovered the isotopic effect associated with the synchronous fractionation of stable isotopes of sulfur sulfate and carbon bicarbonate ions in lake water.Baikal and estuaries of rivers caused by a powerful anthropogenic impact on their ecosystems.
- Developed models describing the relationship between emission flows and methane content on the one hand and temperature in shallow water bodies on the other.
- He established a close connection between the methane and mercury cycle in water and bottom sediments of reservoirs and watercourses.
Based on long-term and extensive fundamental and experimental research, he developed the theory of the formation of geochemical barriers at the water-bottom sediment interface in terms of the influence of hydrogen sulfide and methane cycles conjugated in time and space on the behavior of heavy metals.
- Developed a methodology and methodology for large-scale isotope studies of freshwater reservoirs, watercourses, estuaries and inland seas located on the territory of the former USSR (Don, Kuban, Volga, Selenga, Amu-Darya, Syr-Darya, etc., Lake Baikal, Ladoga, etc., the Azov, Caspian, Black, Aral Seas, White).
- He outlined the zones of anthropogenic influence of large industrial facilities (Baikal Pulp and Paper Mill, Astrakhan Gas Condensate Complex, etc.) on water and bottom sediments and made a quantitative calculation of their contribution to the pollution of reservoirs and watercourses.
- Developed and tested a methodology for identifying oil and petroleum product spills using the stable isotope method and a model of oil transformation in time and space.
- Developed models that adequately describe the transformation of oil and petroleum products in oceanic, marine and freshwater ecosystems over time.
- By studying the distribution of the specific activity of technogenic radionuclides caesium-137 and americium - 241 and information on the distribution of the content of oil components, he determined the rates of modern sedimentation in the Sea of Azov, and the mercury content by the section of bottom sediments in the White Sea, established the "background" values of this element, the depth of occurrence and the time of formation of landslides in the Kandalaksha Bay.
