По результатам измерений на восточном склоне Гданьской впадины Балтийского моря отмечены колебания изотерм. Интерпретация колебаний перманентного галоклина показала, что основной причиной их подъема являются события, при которых при антициклонической циркуляции в водной толще возникает компенсационное течение в придонном слое. Такое компенсационное течение, направленное на восток вдоль южного склона Гданьской впадины, приподнимает изотермы вблизи восточного склона. Максимальная корреляция между глубиной залегания изотермы 5,5 °C и проекцией вектора напряжения трения ветра наблюдалась при западном ветре с небольшой долей северного и с задержкой по времени 38–48 часов. Такая временная задержка обеспечивается инерцией системы. Также по результатам натурных измерений проведена верификация данных модели NEMO, которая показала неточности модели: запаздывание и сглаживание колебаний. Особенно сильные различия отмечаются для верхней части гирлянды термодатчиков, где по модельным данным отсутствуют высокочастотные колебания. У дна высокочастотных колебаний становится значительно меньше и модель достаточно точно, хоть и с запозданием, воспроизводит вертикальные движения выбранной изотермы.</p></abstract><trans-abstract xml:lang="en"><p>At the Atlantic Branch of P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences, an autonomous thermistor chain was developed and manufactured using a modular design. Measurements conducted on the eastern slope of the Gdańsk Basin (Baltic Sea) revealed fluctuations in isotherms. Interpretation of the permanent halocline oscillations showed that their upward shift is primarily caused by events in which anticyclonic circulation in the water column generates a compensatory current in the bottom layer. This compensatory current, flowing eastward along the southern slope of the Gdańsk Basin, lifts the isotherms near the eastern slope. The highest correlation between the depth of the 5.5 °C isotherm and the projection of the wind stress vector was observed under westerly winds with a slight northerly component, with a time lag of 38–48 hours. This delay is attributed to the system’s inertia. Field measurements were also used to validate the NEMO model data, revealing model inaccuracies: a time lag and smoothing of fluctuations. The most significant discrepancies were observed in the upper part of the temperature sensor string, where the model failed to reproduce high-frequency oscillations. Near the bottom, high-frequency fluctuations diminish, and the model reproduces the vertical movements of the selected isotherm with reasonable accuracy, though still with a delay.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Гданьская впадина</kwd><kwd>Балтийское море</kwd><kwd>гирлянда термодатчиков</kwd><kwd>температура воды</kwd><kwd>перманентный галоклин</kwd><kwd>колебания изотерм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Gdansk Basin</kwd><kwd>Baltic Sea</kwd><kwd>thermistor chain</kwd><kwd>water temperature</kwd><kwd>permanent halocline</kwd><kwd>isotherm variations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ИО РАН (тема № FMWE2024-0025).
