D. A. Sabinin''s ideas and their embodiment. Mineral composition of macrophytes is one of the most important indicator of their contribution to a biogeochemical exchange of the World Ocean
The work questions the biogeochemistry concept, and its historical evolution as an independent science. This research shows the structure of modern biogeochemistry, it discusses its goals and objectives, provides the difinition of biosphere. Some parallels in history of evolution of plant physiology, soil science and biogeochemistry are considered. In the research the special attention is given to the ideas of D.A. Sabinin, who proved importance of development of biogeochemical researches in the aquatic environment, and he suggested to use water phototrophs for those researches as they are easy to examine, especially macrophytes, marine macroscopic algae. The research gives much attention to the changes of chemical composition of coastal part of the Black Sea. The sea, including a coastal zone, is considered, on the one hand, as convenient model for a biogeochemical system analyses, and on the other, as strategically important region not only for Russia, but for Europe and Asia. This work features the range change of mineral composition and accumulation capacity of soil, ground deposits and macrophytes. Also this research provides examples of change of mineral composition of coastal and water plants, that grow from the spring region to the mouth of the small river
