Tidal currents flowing around an underwater sill in the strait generate intense tidal internal waves. Forced internal waves exist above the underwater slope. Vertical displacements of water particles reach 20 m. Waves rapidly decay as they propagate away from the strait and slope. They are no longer recorded as far as 12 km from the strait. Tidal currents in the strait reach a speed of 3 m/s and form an intense jet when flowing out of the strait. A strong jet of currents during spring tides presses the instruments on moorings to the bottom.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181325754864">Выполнен анализ измерений температуры, солености и течений на трех заякоренных буйковых станциях, проработавших в течение года в районе сильных приливных течений около пролива Акселоя у устья фиорда Ван Майен на острове Западный Шпицберген. Приливные течения при обтекании подводного поперечного хребта в проливе генерируют интенсивные внутренние волны приливного периода. Над подводным склоном внутренние волны вынужденные. Вертикальные смещения частиц воды достигают 20 м. Волны быстро затухают по мере удаления от пролива и склона. На удалении 12 км от пролива они уже не регистрируются. Приливные течения в проливе достигают скорости 3 м/с и формируют интенсивную струю при вытекании из пролива. Сильная струя течений во время сизигийных приливов прижимает приборы, установленные на буйковых станциях, ко дну. Результаты численного моделирования подтверждают наблюдения о том, что интенсивность вынужденных внутренних волн быстро уменьшается с увеличением расстояния от места генерации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Tidal internal waves</kwd><kwd>supercritical latitudes</kwd><kwd>Spitsbergen</kwd><kwd>tidal currents</kwd><kwd>forced oscillations</kwd><kwd>Akseløya Island</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Приливные внутренние волны</kwd><kwd>закритические широты</kwd><kwd>Шпицберген</kwd><kwd>приливные течения</kwd><kwd>вынужденные колебания</kwd><kwd>остров Акселоя</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Власенко В.И.
