        <p>Исследование посвящено количественной оценке скоростей депонирования органического углерода (Сорг) в донных отложениях малых озер, расположенных на юге Западной Сибири. Изученные водоемы охватывают широкий спектр ландшафтно-климатических условий и типов седиментационных обстановок. Несмотря на локальные размеры, малые озера региона демонстрируют исключительно высокую эффективность долговременного захоронения углерода. Показано, что их способность аккумулировать Сорг сопоставима или даже превышает аналогичные показатели таких признанных углеродных депо, как болота и морские шельфы. В основе работы лежит комплексный анализ донных отложений, включающий радиометрическое датирование (Pb-210, Cs-137) для определения скоростей осадконакопления и возраста слоев, а также морфологический, элементный (CHNS-анализ) и рентгенофазовый анализы. По полученным данным выявлено, что средняя скорость депонирования Сорг в исследованных озерах достигает 462±29 г/м2 в год. Установлено, что основная часть углерода (&amp;gt; 50 % в большинстве случаев) аккумулируется именно в форме органического вещества даже в озерах с интенсивным внутриводоемным (аутигенным) карбонатообразованием. Исследование выявило основные факторы, контролирующие углеродонакопление: продуктивность водных сообществ (фито- и зоопланктон, макрофиты), общая скорость седиментации, зольность осадков (доля минеральной составляющей) и локальные морфометрические особенности озер (глубина, форма котловины). Отсутствие четкой зависимости скоростей депонирования углерода от ландшафтной зональности подчеркивает критическую важность учета локальных условий при моделировании вклада малых озер в глобальный углеродный цикл. Полученные результаты существенно восполняют пробелы региональной углеродной оценки и доказывают значимость малых озер юга Западной Сибири как высокоэффективных и устойчивых природных депо органического углерода в условиях континентального осадконакопления.</p>

        <p>The study is devoted to the quantitative assessment of organic carbon (Corg) deposition rates in the bottom sediments of small lakes located in the south of Western Siberia. The studied water bodies cover a wide range of landscape-climatic conditions and types of sedimentation environments. Despite their local dimensions, the small lakes of the region demonstrate exceptionally high efficiency of long-term carbon burial. It is shown that their capacity to accumulate Corg is comparable to or even exceeds that of such recognized carbon depots as bogs and marine shelves. The work is based on a comprehensive analysis of bottom sediments, including radiometric dating (Pb-210, Cs-137) to determine sedimentation rates and layer ages, as well as morphological, elemental (CHNS analysis), and X-ray diffraction analyses. According to the obtained data, the average Corg deposition rate in the studied lakes reaches 462±29 g/m2 per year. It has been established that the majority of carbon (&amp;gt; 50 % in most cases) accumulates specifically in the form of organic matter, even in lakes with intensive intra-basin (authigenic) carbonate formation. The study revealed the main factors controlling carbon accumulation: productivity of aquatic communities (phytoplankton, zooplankton, macrophytes), total sedimentation rate, sediment ash content (mineral fraction proportion), and local morphometric features of the lakes (depth, basin shape). The absence of a clear dependence of carbon deposition rates on landscape zonality underscores the critical importance of considering local conditions when modeling the contribution of small lakes to the global carbon cycle. The obtained results substantially fill gaps in regional carbon assessment and prove the significance of small lakes in the south of Western Siberia as highly efficient and stable natural depots of organic carbon under conditions of continental sedimentation.</p>
