Origin and Distribution of Organic Compounds in the Marine Environment,elf and with a variety of other elements to form long carbon chains, rings, and complex organic compounds, the total number of which is estimated to be approximately four million. In comparison, the hundred-plus elements other than carbon combine with each other to form about 70,000 inorganic compou

,Humification—A Major Biogeochemical Phenomenon,aceous compounds synthesized in the biosphere. Photosynthesis is a remarkable biochemical phenomenon, initiating the assimilation of atmospheric carbon dioxide and leading to the synthesis of an enormous number of organic compounds. A living cell is a unique biochemical laboratory where assimilated

Diagenetic Transformations of Humic Compounds,e a complex assemblage of aliphatic and aromatic substances, intermingled in such a manner that they have lost their individual identities. Polymerization and polycondensation reactions make the molecules large and condensed. Once the process of humifícation has been completed, the resulting molecul

Role of Humic Compounds in Aquatic Productivity, Humic compounds also play a unique role in the fertility of coastal waters by strongly influencing the primary productivity of nearshore areas. The oceans of the world are complex ecosystems, exhibiting a high degree of temporal and spatial variability in most chemical, physical, and biological par
