Abstract
The article presents informative organogeochemical indicators used in oceanology to characterize biogeochemical processes. A classification based on data on suspended particulate matter, plankton, benthos, bottom sediments, and sea, river, and pore water has been developed. Clusters have been identified that include the elemental and isotopic composition of organic matter (OM), the group composition of lipids, aliphatic and alicyclic hydrocarbons, higher alcohols, macromolecular acids and ketones, isoprenoids, lignin and its structural monomers, and PAHs. The most informative indices are considered, which make it possible to assess the genesis of the original OM, the degree of its transformation, sources, and the ratio of aquatic and terrigenous components. These indices reflect the influx of riverine and aeolian material and permafrost thawing and make it possible to reconstruct the temperature of river waters and coastal upwellings. They significantly complement biooceanological, lithological, and geochemical studies and expand the biogeochemical methodology for studying the carbon cycle.
摘要 文章介绍了海洋学中用于描述生物地球化学过程的信息有机地球化学指标。根据悬浮颗粒物、浮游生物、底栖生物、底层沉积物以及海水、河水和孔隙水的数据，制定了一种分类方法。已确定的群组包括有机物（OM）的元素和同位素组成、脂质、脂肪族和脂环族碳氢化合物、高级醇、大分子酸和酮类、异丙烯酸、木质素及其结构单体和多环芳烃的群组组成。考虑到信息量最大的指数，可以评估原始 OM 的成因、转化程度、来源以及水生和陆生成分的比例。这些指数反映了河水和风化物的流入以及永久冻土的融化，并能重建河水和沿岸上升流的温度。它们极大地补充了生物海洋学、岩石学和地球化学研究，拓展了研究碳循环的生物地球化学方法。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
