Данные морских экспедиционных измерений впервые для российской части Арктики сопоставлены с данными буксируемого необитаемого подводного аппарата «Видеомодуль», разработанного в Институте океанологии им. П.П. Ширшова РАН. Проведенный анализ показывает, что эмиссия метана от бактериальных матов в Арктике вносит ограниченный вклад в повышение концентрации CH4 в приводном слое атмосферы. Их влияние заметно только в мелководных зонах (глубиной до 50 м), где насыщенные метаном пузырьки успевают достичь поверхности воды без его полного окисления в толще океана. При этом наблюдаются кратковременные пики (до нескольких минут) повышенных значений концентрации CH4, достигающие 3 ppm и выше. Основным фактором изменчивости концентрации CH4 в атмосфере является направление переноса воздушных масс: при адвекции с севера и запада фиксируются минимальные значения концентрации CH4 (1,98 ppm); при выносе воздушных масс с материка, напротив, концентрация метана увеличивается (до 2,10 ppm при выносе с полуострова Ямал).</p></abstract><trans-abstract xml:lang="en"><p>The article presents the values of methane concentration in the near-surface layer of atmospheric air directly measured from the board of “Akademik Mstislav Keldysh” research vessel in the Kara and Barents Seas in the summer of 2024. It is the first time when the marine expeditionary data for the Russian part of the Arctic have been compared with the data obtained by “Videomodule” towed unmanned underwater vehicle engineered at the Shirshov Institute of Oceanology of the Russian Academy of Sciences. The analysis shows that bacterial mats in areas of methane seepage in the Arctic have a limited contribution to the increase in CH4 concentration in the near-surface layer of the atmosphere. Their influence is likely to be noticeable only in shallow areas (up to 50 m deep), where methane can reach the water surface without being fully oxidized in the ocean. At the same time, short-lived peaks (lasting up to several minutes) of elevated CH₄ concentrations are observed, reaching 3 ppm or higher. The main factor influencing   the variability of atmospheric CH4 concentrations is the direction of air mass transport: when air masses are advected from the north and west, minimum CH4 concentrations (1.98 ppm) are recorded; conversely, when air masses are carried away from the   mainland, methane concentrations increase (up to 2.10 ppm when from the Yamal Peninsula).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Арктика</kwd><kwd>концентрация метана</kwd><kwd>подводная видеосъемка</kwd><kwd>парниковый эффект</kwd><kwd>экспедиционные наблюдения</kwd><kwd>эмиссия метана</kwd><kwd>бактериальные маты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Arctic</kwd><kwd>methane concentration</kwd><kwd>underwater video recording</kwd><kwd>greenhouse effect</kwd><kwd>expeditionary observations</kwd><kwd>methane emission</kwd><kwd>bacterial mats</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Экспедиционные работы выполнены в рамках государственного задания Минобрнауки России для ИО РАН (тема № FMWE-2024-0024).
