Анализ изменения количественных и структурных показателей фитопланктона в западной и центральной части Среднего Каспия за последние десятилетия, в том числе по данным дистанционного зондирования.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Материал    получен    в    2004–2008    гг.    и 2019–2022 гг. в различные сезоны года на 40 станциях в центральной и западной части Среднего Каспия. Пробы фитопланктона отбирали с 4–6  горизонтов.  Всего  проанализировано  300  проб  фитопланктона.</p><p>Определение видов и подсчет числа клеток проводили под световым микроскопом «Эргавал». В вопросах номенклатуры руководст‐ вовались WoRMS.</p></sec><sec><title>Результаты</title><p>Результаты. В весенних фитоценозах исследованного района доминируют традиционных для Каспийского моря – диатомеи Cyclotella caspia и динофлагелляты Prorocetrum micans. Максимум численности  C. caspia  (5,0  х  104   кл/л),  фиксировался  на  глубинах 35–40 м. Летом максимум биомассы фитопланктона (2,2 г/м3) отмечен в сезонном термоклине и формировался за счет мелких флагеллят и динофлагеллят. Биомасса фитопланктона в период зимних цветений достигала   4,5–5,0   г/м3     и   определялась   развитием   диатомовых (до 96–99%). Зимние цветения формировались традиционными для моря видами диатомовых, так и видами‐вселенцами Pseudo‐nitschia seriata и Cerataulina pelagica.</p></sec><sec><title>Заключение</title><p>Заключение. Показано, что в Среднем Каспии для зимнего и осеннего сезонов характерен высокопродуктивный статус. В январе–феврале, отмечаются периодические цветения диатомовых водорослей, что подтверждается спутниковыми данными и наблюдениями in situ. В летний период биомассу фитопланктона определяет массовое развитие динофлагеллят в слое сезонного термоклина, что не фиксируется дистанционными  методами. В  осеннем фитопланктоне основную роль играет диатомовая компонента, представленная в основном видами‐вселенцами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.  Analysis  of  changes  in  quantitative  and  structural  indicators  of phytoplankton in the western and central part of the middle Caspian Sea over the past decades, including according to remote sensing data.</p></sec><sec><title>Material  and  Methods</title><p>Material  and  Methods.  The  data  was  obtained  in  2004–2008  and 2019–2022 at different seasons of the year at 40 stations in the central and western part of the middle Caspian Sea. Phytoplankton samples were taken  from  4–6 layers.  A  total  of  300 samples  of phytoplankton  were analyzed. Determination of species and counting of the number of cells was carried out under the “Ergaval” light microscope. WoRMS guided matters of nomenclature.</p></sec><sec><title>Results</title><p>Results. The spring phytoplankton is dominated by the species traditional for the Caspian Sea – Cyclotella caspia diatoms and Prorocetrum micans dinoflagellates. The maximum abundance of C. caspia (5.0 x 104 cell/l) was recorded at depths of 35–40 m. In summer, the maximum phytoplankton biomass (2.2 g/m3) was noted in the seasonal thermocline and was formed due to small flagellates and dinoflagellates. Phytoplankton biomass during winter blooms reached 4.5–5.0 g/m3 and was determined by the development of diatoms (up to 96–99%). Winter blooms were formed by the diatom species traditional for the sea, as well as by the Pseudo‐nitschia seriata and Cerataulina pelagica species.</p></sec><sec><title>Conclusion</title><p>Conclusion. It is shown that in the middle Caspian Sea, the winter and autumn seasons are characterized by a highly productive status. In January–February, periodic blooms of diatoms are observed, as confirmed by satellite data and in situ observations. In summer, phytoplankton biomass is determined by the mass development of dinoflagellates in the seasonal thermocline layer, which has not been recorded by remote methods. In the autumn phytoplankton the main role is played by the diatom component, represented mainly by alien species.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Фитопланктон</kwd><kwd>дистанционное зондирование</kwd><kwd>диатомовые</kwd><kwd>виды‐вселенцы</kwd><kwd>Средний Каспий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Phytoplankton</kwd><kwd>remote  sensing</kwd><kwd>diatoms</kwd><kwd>dinoflagellates</kwd><kwd>alien  species</kwd><kwd>Middle Caspian</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность д.б.н.
