Температура и соленость поверхностного слоя, степень стратификации водного столба существенно варьировали по акватории залива. Содержание биогенных элементов превышало пороги лимитирования развития фитопланктона, суммарная биомасса фитопланктона составляла 13,46±9,00 мг С/м3, концентрация хлорофилла “a” — 0,78±0,43 мг/м3; биомасса пикофитопланктона — 0,18±0,27 мг С/м3. Наибольшая биомасса отмечена у фронтальных зон. Выявлено три сообщества фитопланктона, достоверно различающихся по структуре.</p></abstract><trans-abstract xml:lang="en"><p>The species composition and phytoplankton biomass, concentrations of chlorophyll “a” (Chl) and nutrients in the surface water layer, and concurrent hydrophysical conditions were studied in the Onega Bay of the White Sea during June, 2015. The temperature and salinity of surface water layer and the water column stability varied significantly in the bay. The nutrients concentrations exceeded the threshold limiting of phytoplankton development. The phytoplankton abundance was relatively low, mean values were: total phytoplankton biomass — 13,46±9,00 mg C/m3, concentration of chlorophyll “a” — 0,78±0,43 mg/m3, picophytoplankton biomass — 0,18±0,27 mg C/m3. The highest phytoplankton biomass was found near frontal zones. Structural analysis has revealed three phytoplankton communities that significantly have differed in structure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Белое море</kwd><kwd>Онежский залив</kwd><kwd>фитопланктон</kwd><kwd>пикофитопланктон</kwd><kwd>Skeletonema costatum sensu lato</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the White Sea</kwd><kwd>the Onega Bay</kwd><kwd>phytoplankton</kwd><kwd>picophytoplankton</kwd><kwd>Skeletonema costatum sensu lato</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ferland J., Gosselin M., Starr M.
