Для получения оценок привлекается трехмерная экогидродинамическая модель, основанная на модели океана Принстонского университета (США). Эта модель включает блок морского льда с 7 категориями и 11-компонентный блок морской пелагической экосистемы, разработанный в Санкт-Петербургском филиале Института океанологии им. П. П. Ширшова РАН. Сравнение результатов расчета для периода 1998—2007 гг. со спутниковыми данными показало, что модель воспроизводит основные черты эволюции поверхностной температуры, границы сезонного ледового покрова, поверхностной концентрации хлорофилла-a и первичной продукции фитопланктона в Баренцевом море. Модельные оценки средней годовой первичной продукции фитопланктона всего моря оказались в 1.5—2.3 раза больше аналогичных оценок по спутниковым данным. Основные причины расхождения оценок заключаются в том, что модель учитывает производство первичной продукции фитопланктона под паковыми льдами и в маргинальной зоне льда, а спутниковые данные относятся исключительно к открытой воде. Более того, оценка первичной продукции фитопланктона по спутниковым данным занижает ее значения из-за подповерхностного максимума хлорофилла. За период 1998—2007 гг. максимальная в сезонном цикле модельная площадь льда в море уменьшилась примерно на 15 %. Это уменьшение сопровождалось увеличением средней годовой первичной продукции фитопланктона моря на 54 и 63 % соответственно по спутниковым данным и модельным расчетам для открытой воды. Согласно модельным расчетам для всей акватории моря, оно составляет только 19 %. Сделан вывод, что адекватные оценки первичной продукции в покрытых льдом морях могут быть получены только на основе экогидродинамических моделей, включающих морской лед.</p></abstract><trans-abstract xml:lang="en"><p>This study is aimed to assess the impact of sea ice on the primary production of phytoplankton in the Barents Sea. To get the estimations, we apply a three-dimensional eco-hydrodynamic model based on the Princeton Ocean Model which includes a module of sea ice with 7 categories and the 11-component module of marine pelagic ecosystem developed in Saint-Petersburg Department of the P.P. Shirshov Institute of Oceanology of RAS. The comparison of the model results for the period 1998—2007 with satellite data showed that the model reproduces the main features of the evolution of the sea surface temperature, seasonal changes in the ice extent, surface chlorophyll-a concentration and the primary production of phytoplankton in the Barents Sea. Model estimates of the annual primary production of phytoplankton for the whole sea turned out to be 1.5—2.3 times higher than similar estimates from satellite data. The main reason for this discrepancy is that the model takes into account the production of the primary production of phytoplankton under the pack ice and the marginal ice zone, and satellite data refer exclusively to the open water. Moreover, the evaluation of the primary production of phytoplankton from satellite data underestimates its importance due to subsurface maximum of chlorophyll. During the period 1998—2007, the modelled maximal (in the seasonal cycle) sea ice area has decreased by 15 %. This reduction was accompanied by an increase in the annual primary production of phytoplankton of the sea at 54 and 63 %, based, respectively, on satellite data and the model for the open water. According to the model calculations for the whole sea area, the increase is only 19 %. We conclude that an adequate assessment of the primary production in ice-covered seas can only be obtained on the basis of eco-hydrodynamic models, including sea ice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ледовый покров</kwd><kwd>первичная продукция</kwd><kwd>моделирование</kwd><kwd>Баренцево море</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ice cover</kwd><kwd>primary production</kwd><kwd>modeling</kwd><kwd>the Barents Sea</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была поддержана Российским фондом фундаментальных исследований, грант РФФИ № 13-05-00652 и № 16-55-76021.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Smedsrud L.
