One of many easy innovations of ocean biogeochemistry is that of an ocean with tremendous energetic boundary zones and separation limitations of intensive biochemical interactions. The components of those zones are characterised via a pointy reduce of point migration depth and accordingly the lessen of their concentrations gave the limits for the naming of the geochemical boundaries (Perelman, 1972). For the needs of biogeo chemistry an important ones are the bounds of separation among river-sea, ocean-atmosphere, and water-ground (Lisitzin, 1983). the main complex of them is the river-sea boundary, the place the biogeochemical approaches are the main lively and complex (Monin and Romankevich, 1979, 1984). the need of learning natural topic in rivers, mouth areas and adjacent sea aquatories has been again and again mentioned by means of v.I. Vernadsky (1934, 1960) who famous either the significance of registration of reliable and liquid run-off of rivers, getting into the ocean, and "the caliber and the nature of these components, that are washed-down into the sea", emphasizing that "wash-down of natural elements into the ocean is of significant value". The curiosity in learning natural topic in common waters, together with river and sea waters, has grown significantly over the past 30 years. in this interval crucial fabric used to be accrued at the content material and composition of natural subject in numerous forms of river waters of the USSR, and this was once released in papers via B.A Scopintzev, advert. Semenov, M.V.
