В работе на примере результатов комплексной геолого-геофизической экспедиции на НИС «Академик Опарин» (21 сентября – 31 октября 2017 г.) установлена закономерность изменчивости концентрации метана в поверхностном слое морской воды: после каждого землетрясения средний показатель роста составил 70 %, средний период роста 10 ч; падение уровня концентрации метана в морской воде достигало 10–30 % за 2–4 ч до сейсмического события. Снижение концентраций метана происходит независимо от глубины землетрясения. Полученные результаты согласуются с литературными данными, а также материалами газогеохимического мониторинга и позволяют обсуждать наличие сейсмозависимого газогеохимического режима не только газонасыщенных осадков, но и толщи вод Японского моря.</p></abstract><trans-abstract xml:lang="en"><p>A spatial distribution of methane dissolved in sea water is a critical but poorly understood factor in the context of seismic activity. Based on the results of the RV AKADEMIK OPARIN integrated geological-geophysical expedition (September 21 – October 31, 2017), this paper deals with the regularities of methane concentration variability in the surface layer of the Sea of Japan: the average growth and the average growth period were 70 % and 10 h, respectively, after each earthquake whereas a decrease in methane concentration in the sea water was 10–30 % 2–4 h before a seismic event. A decrease in methane concentration occurs irrespectively of the depth of an earthquake. The results obtained show good agreement with the published data and gaseous-geochemical monitoring materials, thus making it possible to associate seismic-related gaseous-geochemical regime not only with gas-saturated sediments but also with the water column of the Japan Basin (Sea of Japan).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метан</kwd><kwd>землетрясение</kwd><kwd>Японское море</kwd><kwd>переходная зона</kwd><kwd>окраинные моря</kwd></kwd-group><kwd-group xml:lang="en"><kwd>methane</kwd><kwd>earthquake</kwd><kwd>Sea of Japan</kwd><kwd>transition zone</kwd><kwd>marginal seas</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Экспедиция выполнена при поддержке Совета по гидросфере Земли ФАНО комплексных геолого-геофизических, газогеохимических, гидрохимических и океанографических исследований в северной части Японского моря, на северо-восточном склоне о-ва Сахалин (Охотское море) и в сейсмоактивной зоне Татарского пролива. Работа выполнена в рамках Гостемы АААА-А19-119122090009-2 «Исследование состояния и изменений природной среды на основе комплексного анализа и моделирования гидрометеорологических, геохимических, геологических процессов и ресурсов Мирового океана» (2020–2023 гг.) и при поддержке гранта Президента Российской Федерации для молодых ученых МК-357.2021.1.5. Результаты исследований вносят важный вклад в реализацию международного проекта «Геосистемы и минеральные ресурсы зоны перехода «континент – океан» и открытого океана» (ГЕОМИР) в рамках Десятилетия ООН наук об океане в интересах устойчивого развития (2021–2030 гг.).</funding-statement><funding-statement xml:lang="en">The expedition took place with the support of Council for the Hydrosphere of Earth of Federal Agency for Scientific Organizations, provided for the integrated geological-geophysical, gaseous-geochemical, hydrochemical and oceanographic studies in the northern Sea of Japan, on the northeastern slope of the Sakhalin Island (Sea of Okhotsk), and in the seismoactive zone of the Tatar Strait. The work was done as part of the state assignment АААА-А19-119122090009-2 "Study of the Environmental State and Environmental Changes Based on the Integrated Analysis and Modeling of Hydrometeorological, Geochemical and Geological Processes and Resources of the World Ocean" (2020–2023 гг.) and supported in part by Grant of the President of the Russian Federation for Young Scientists МК-357.2021.1.5. The research contributes much to the implementation of the international project "Geosystems and Mineral Resources of the "Continent – Ocean" Transition Zone and Mid-Ocean" (GEOMIR) within the UN Decade of Ocean Science for Sustainable Development (2021–2030).</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">Буров Б.А., Саломатин А.С., Обжиров А.И.
