Summary
Summary
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.

Choice Review
Artemyev discusses studies of river-sea systems by Russian scientists along with some Western scientists through the early 1990s. The focus is on the type and fate of organic matter in river-sea systems, with emphasis on the Amazon (tropical) and Dvina (northern) river systems. Chemical aspects of other riverine systems are discussed. The author provides a valuable compilation of dissolved and particulate organic matter properties in riverine, estuarine, and deltaic waters and sediments. A methods chapter contains cursory information of general but not specific use. Chapters on river runoff and estuarine waters contain a general discussion of compositions or processes followed by a discussion of major river-sea systems in different climatic or geomorphologic environments. The final chapter focuses on transformation of organic matter. Language difficulties do not detract from the usefulness of the book, but it reads more cryptically because of them. Useful for graduate students, researchers, and professionals working in riverine and estuarine environments. N. W. Hinman University of Montana
