Water column PP (IPP) value was equal to 28±13 mgC m<sup>-2</sup> day<sup>-1</sup> on average that testify ultraoligotrophic conditions. IPP was limited by low incident and underwater photosynthetically available radiation and nitrate concentration. Ammonium concentration partly compensates lack of dissolved nitrogen.</p></abstract><trans-abstract xml:lang="ru"><p>По данным 69-го рейса нис “Академик Мстислав Келдыш” (сентябрь 2017 г.) впервые исследована пространственная изменчивость первичной продукции Восточно-Сибирского моря на акватории большого масштаба. Величина для столба воды интегральной первичной продукции (ИПП) составила 28±13 мгС/м<sup>2</sup> в день, что свидетельствует об ультраолиготрофии исследованного района в осенний период. ИПП была лимитирована низкой надводной и подводной освещённостью и содержанием нитратов. Аммоний частично компенсировал недостаток неорганического азота и являлся буфером, препятствующим азотному голоданию фитопланктона.</p></trans-abstract><kwd-group xml:lang="en"><kwd>primary production</kwd><kwd>chlorophyll</kwd><kwd>East Siberian Sea</kwd><kwd>photosynthetically available radiation</kwd><kwd>nutrients</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первичная продукция</kwd><kwd>хлорофилл</kwd><kwd>Восточно-Сибирское море</kwd><kwd>надводная и подводная освещённость</kwd><kwd>нитраты</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Presidium of the Russian Academy of Sciences</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Президиум Российской академии наук</institution></institution-wrap></funding-source><award-id></award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Arrigo K. R., van Dijken G. L. // Progr. in Oceanogr. 2015.
