One of the basic concepts of ocean biogeochemistry is that of an
ocean with extremely active boundary zones and separation
boundaries of extensive biochemical interactions. The areas of
these zones are characterized by a sharp decrease of element
migration intensity and consequently the decrease in their
concentrations gave the boundaries for the naming of the
geochemical barriers (Perelman, 1972). For the purposes of biogeo
chemistry the most important ones are the boundaries of separation
between river-sea, ocean-atmosphere, and water-ground (Lisitzin,
1983). The most complicated of them is the river-sea boundary,
where the biogeochemical processes are the most active and
complicated (Monin and Romankevich, 1979, 1984). The necessity of
studying organic matter in rivers, mouth regions and adjoining sea
aquatories has been repeatedly pointed out by v.I. Vernadsky (1934,
1960) who noted both the importance of registration of solid and
liquid run-off of rivers, coming into the sea, and "the quality and
the character of those elements, which are washed-down into the
sea", emphasizing that "wash-down of organic substances into the
sea is of great value". The interest in studying organic matter in
natural waters, including river and sea waters, has grown
considerably over the last 30 years. During this period essential
material was collected on the content and composition of organic
matter in various types of river waters of the USSR, and this was
published in papers by B.A Scopintzev, AD. Semenov, M.V.
