Vertical distribution of basic classes of dissolved and suspended organic substance in central regions of the Black and Aegean Sea

Data on the content of dissolved and suspended organic substance (carbohydrates, protein, lipids and hydrocarbons) in a layer of 0-260 m are obtained proceeding from investigations conducted during the 104th cruise of the research ship „Akademik Kovalevsky". Peculiarities of distribution of these compounds in the depth due to the presence of the hydrogen sulphide zone in the Black Sea are found. Certain organic compounds are fractionated by molecular masses. Vertical profiles of distribution of certain fractions of carbohydrates and protein are presented.Приведены данные о содержании основных классов растворенных и взвешенных органических веществ (углеводов, белка, липидов, углеводородов). Даны результаты фракционирования некоторых из этих соединений по молекулярным массам. Показаны особенности вертикального распределения органических соединений
