Хотя Баренцево море относится к числу ледовитых, оно, в отличие от других арктических морей, никогда не покрывается льдом полностью. Одним из параметров, характеризующих изменение ледового режима, является дата полного очищения ото льда. В исследовании использованы данные о концентрации (сплочённости) льда Climate Data Record (CDR) NOAA/NSIDC с 1979 по 2019 г. и данные океанского реанализа GLORYS12V1 (Global Ocean Physics Reanalysis) с 1993 по 2019 г. Выполненный анализ пространственно-временной изменчивости даты полного очищения ото льда для акватории Баренцева моря с использованием метода кластерного анализа HDBSCAN позволил выделить районы (кластеры) с синхронной динамикой даты полного очищения ото льда. Ряд выделенных районов находятся на пути распространения атлантических вод в Баренцевом море, что позволило связать выявленную временную изменчивость даты полного очищения ото льда с изменчивостью переноса атлантических вод через западную границу моря. На всей акватории Баренцева моря после 2003 г. наблюдается устойчивое смещение сроков сезонного очищения ото льда на более ранние. При этом каждому из выделенных шести районов свойственна своя динамика и скорость изменений даты полного очищения ото льда. Заметное влияние на дату полного очищения ото льда адвективного потока тепла через западную границу Баренцева моря выявлено для районов в центральной и восточной частях моря. Для разных районов максимальный коэффициент корреляции даты полного очищения ото льда наблюдается при разных временных сдвигах (от 0 до 6 мес.) адвективного потока тепла. Величина временного сдвига косвенно указывает на время прохождения тепловым сигналом расстояния от западной границы моря до соответствующего района. Сохранение тенденции к возрастанию продолжительности безледного сезона в Баренцевом море является одним из проявлений нарастающей «атлантификации» приатлантической Арктики, вследствие чего открываются новые перспективы для экономической деятельности в этом арктическом регионе. В частности, это влияет на транспортировку и условия добычи углеводородов, также на воспроизводство, распределение и поведение основных промысловых видов рыбы в Баренцевом море.</p></abstract><trans-abstract xml:lang="en"><p>The Barents Sea is one of the key areas in the Arctic for monitoring of climate change. Although the Barents Sea is one of the Arctic seas, it is never completely covered with ice. One of the parameters characterizing the change in the ice regime is the date of ice retreat (DOR). The study is based on ice concentration data from the NOAA / NSIDC Climate Data Record (CDR) from 1979 to 2019 and the GLORYS12V1 ocean reanalysis data from 1993 to 2019. The analysis of the spatial and temporal variability of DOR for the Barents Sea using the HDBSCAN cluster analysis method made it possible to identify areas (clusters) with the synchronous dynamics of DOR. A number of the identified areas are located on the path of the Atlantic waters (AW) in the Barents Sea, which made it possible to relate the revealed temporal variability of the DOR to the variability of the AW transport across the western boundary of the sea. Over the entire Barents Sea, after 2003, there has been a steady trend in the timing of seasonal ice removal to earlier ones. At the same time, each of the six regions identified has its own dynamics and rate of changes in DOR. A noticeable effect of the advective heat flux across the western boundary of the Barents Sea on the DOR was revealed for areas in the central and eastern parts of the sea. At the same time, for different regions, the maximum correlation coefficient is observed at different time lags (from 0 to 6 months). The value of the time lag indirectly indicates the time the thermal signal travels the distance from the western boundary of the sea to the corresponding region. The continuing trend towards an increase in the duration of the ice–free season in the Barents Sea is one of the manifestations of the growing “Atlantification” of the East Atlantic sector of the Arctic Ocean which opens up new prospects for socio–economic activity in this Arctic region.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морской лед</kwd><kwd>даты полного очищения ото льда</kwd><kwd>Баренцево море</kwd><kwd>«атлантификация»</kwd><kwd>кластерный анализ</kwd><kwd>изменение климата</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sea ice</kwd><kwd>dates of ice retreat</kwd><kwd>Barents Sea</kwd><kwd>“atlantification”</kwd><kwd>cluster analysis</kwd><kwd>climate change</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена при финансовой поддержке гранта РНФ 19–17–00110 и при поддержке Междисциплинарной научно-образовательной школы Московского государственного университета имени М.В.
