Оценивались тренды указанных показателей. Для исследований использовались данные спутниковых наблюдений SeaWiFS и MODIS-Aqua, MODIS-Terra. Выявлены тенденции к повышению температуры на 4 % по среднегодовым данным в глубоководной западной части моря за 18-тилетний период. Повышение происходило преимущественно за счет зимнего сезона. Понижение первичной продукции фитопланктона отмечено в пределах 16,4–18,6 % от первоначального уровня по среднегодовым величинам при уровне значимости р &lt; 0,1, по всей глубоководной области. Снижение первичной продукции наблюдалось летом. Статистически значимых направленных изменений концентрации хлорофилла по осредненным данным за 18 лет не отмечено. В различных частях глубоководной зоны направленность межгодовых и сезонных изменений всех показателей была сходной. Наметившаяся тенденция к снижению продуктивности фитопланктона за последние годы может привести к перестройке фитопланктонного сообщества.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of long-term seasonal changes in the concentration of chlorophyll, the maximum rate of phytoplankton photosynthesis and water temperature in the surface layer of the open waters Black Sea from 1998 to 2015 has been carried out. The trends of these indicators were assessed. For the research, we used the data of satellite observations SeaWiFS and MODIS-Aqua, MODIS-Terra. Typical positive temperature trends of 4 % in the deep-water western part of the sea. An annual temperature rise in deep-water areas was noted in the western cyclonic circulation by 0.038 °C. According to average annual data in other areas, no increase was found. The increase was mainly due to the winter season. Negative trends of primary phytoplankton production within 16.4–18.6 % of the initial level according to average annual values throughout the deep-water area. Significance level — p &lt; 0.1. A decrease in primary production was observed in the summer. There were no statistically significant directional changes in </p><p>chlorophyll concentration based on averaged data over 18 years. In different parts of the deep-sea area, the direction of interannual and seasonal changes in all indicators was similar. The emerging trend towards a decrease in phytoplankton productivity in recent years may lead to a restructuring of the phytoplankton community.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многолетние тренды</kwd><kwd>сезонная изменчивость</kwd><kwd>температура воды</kwd><kwd>концентрация хлорофилла а</kwd><kwd>продуктивность фитопланктона</kwd><kwd>глобальное потепление</kwd><kwd>Черное море</kwd><kwd>спутниковые измерения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>long-term trends</kwd><kwd>seasonal variability</kwd><kwd>water temperature</kwd><kwd>chlorophyll a concentration</kwd><kwd>phytoplankton productivity</kwd><kwd>global warming</kwd><kwd>Black Sea</kwd><kwd>satellite measurements</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания ФИЦ ИнБЮМ по теме «Функциональные, метаболические и токсикологические аспекты существования гидробионтов и их популяций в биотопах с различным физико-химическим режимом» (№ гос. регистрации 121041400077–1) и частично в рамках государственного задания по теме № 0827-2018-0002 «Развитие методов оперативной океанологии на основе междисциплинарных исследований процессов формирования и эволюции морской среды и математического моделирования с привлечением данных дистанционных и контактных измерений».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the state assignment of the Federal Research Center IBSS on the topic “Functional, metabolic and toxicological aspects of the existence of aquatic organisms and their populations in biotopes with different physicochemical regimes” (state registration number 121041400077–1).
