Показано, что вертикальное распределение Хл «а» определяется его концентрацией в поверхностном слое и гидрофизическими условиями, а распределение ПП по вертикали является убывающей функцией глубины и света. В конце весны-начале лета, при лимитировании роста фитопланктона биогенными элементами, может наблюдаться образование подповерхностного максимума Хл «а», вследствие чего возрастает вклад этого слоя в интегральную ПП. Рассчитаны показатели продуктивности фитопланктона в прибрежной зоне в зависимости от трофического состояния вод (олиготрофное, мезотрофное, эвтрофное). Показана значительная вариация величин Х «а» (1,2–19,8 мг·м-3) и ПП фитопланктона (40–2153 мгC·м-2·сут-1) от олиготрофного уровня зимой (декабрь-март) до эвтрофного – весной (апрель) и летом в периоды максимального развития фитопланктона. Проведен анализ предлагаемых для Балтийского моря алгоритмов расчета ПП, включающих известные уравнения для описания зависимости фотосинтеза от света, предложенные Дж. Стиллом, Т. Платтом и А. Яссби-Т. Платтом. Уравнения Т. Платта и А. Яссби-Т. Платта обеспечивали лучшее соответствие вычисленных для разных глубин значений ПП с данными ее натурных измерений на выбранных горизонтах, а уравнение Дж. Стилла точнее воспроизводило интегральные величины ПП.</p></abstract><trans-abstract xml:lang="en"><p>Field measurements conducted in the coastal zone of the Russian sector of the Baltic Sea south-eastern part from April 2008 to April 2009 allowed to describe patterns of seasonal distribution of the chlorophyll a concentration (Chl) and primary production (PP) of phytoplankton in the water column under environmental conditions. It is shown that the vertical distribution of Chl is determined by its concentration in the surface layer and hydrophysical conditions, while the vertical distribution of PP performs a decreasing function of depth and light. In late spring-early summer, when the growth of phytoplankton is limited by nutrients, the subsurface maximum of Chl can be observed; as a result, contribution of this layer to the integral PP increases. Indicators of phytoplankton productivity in the coastal zone have been calculated depending on the trophic state of waters (oligotrophic, mesotrophic, eutrophic). Significant variations of Chl (1.2-19.8 mg·m-3) and PP (40-2153 mgC·m-2·day-1) values are observed from the oligotrophic level in the winter period (December-March) to eutrophic level in spring (April) and summer during maximum phytoplankton growth. The analysis has been conducted of the well-known algorithms for calculating PP, proposed for the Baltic Sea, including the equations for detecting the dependence of photosynthesis on the light, presented by J. Still, T. Platt, and A. Jassby-T. Platt. Тhe equations of T. Platt and A. Yassby-T. Platt provided a better correspondence of the PP values calculated for different depths to the data of field measurements of PP at these depths, and J. Still's equation better reproduced the average value of water column PP. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>первичная продукция</kwd><kwd>хлорофилл «а»</kwd><kwd>вертикальное распределение</kwd><kwd>зависимость «фотосинтез-свет»</kwd><kwd>Балтийское море</kwd><kwd>MODIS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary production</kwd><kwd>chlorophyll “a”</kwd><kwd>vertical distribution</kwd><kwd>light curves</kwd><kwd>Baltic Sea</kwd><kwd>MODIS</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования проведены в рамках государственного задания Института океанологии им П.
