Приведены результаты океанографических наблюдений, выполненных с борта НИС «Дальние Зеленцы» на разрезе Кольский меридиан в 2017–2023 гг. Основной акцент сделан на оценках характеристик фронтальных разделов в области северной части Полярной фронтальной зоны Баренцева моря в осенний, зимний и весенний периоды. Для оценки аномалий ледовитости использовались данные Мирового центра данных по морскому льду (AARI WDC Sea-Ice). Выполнено сравнение результатов наблюдений в северной части разреза вблизи прикромочной ледовой зоны с характеристиками температуры и солености из глобальных океанологических баз. Для сравнения привлекались продукты MERCATOR PSY4QV3R1, CMEMS GLORYS12v1 и TOPAZ5. На всех разрезах были обнаружены высокоградиентные зоны, выраженные в поле температуры и солености, на разном расстоянии от кромки ледового поля. Было подтверждено, что в западном районе Баренцева моря отмечается устойчивый тренд к сокращению площади ледового покрова последние три десятилетия. Показано, что самый северный из фронтальных разделов Полярной фронтальной зоны Баренцева моря на оси разреза Кольский меридиан находилcя на расстоянии от 48 до 290 км от кромки ледовых полей, градиенты температуры варьировались от 0,10 до 0,20 °C/км, солености — от 0,012 до 0,025 епс/км, ширина фронтальной зоны не превышала 55 км. Наилучшее соответствие результатам измерений отмечено с данными продукта MERCATOR PSY4QV3R1

This study presents oceanographic observations from the R/V Dalnie Zelentsy along the Kola Section (2017–2023), focusing on the northern Polar Front during autumn, winter, and spring. Sea ice anomalies were estimated using data from the World Data Center for Sea Ice (AARI WDC Sea-Ice). Observational data near the Marginal Ice Zone were compared with temperature and salinity fields from global oceanographic datasets, including MERCATOR PSY4QV3R1, CMEMS GLORYS12v1, and TOPAZ5. High-gradient temperature and salinity zones were observed at varying distances from the ice edge along all sections. Over the past three decades, the western Barents Sea has experienced a steady decline in sea ice cover. The northernmost Polar Front along the Kola Section ranged from 48 to 290 km from the ice edge, with temperature gradients of 0.10–0.20 °C/km and salinity gradients of 0.012–0.025 psu/km. The frontal zone width did not exceed 55 km. Among the assessed data products, MERCATOR PSY- 4QV3R1 showed the highest correlation with in situ measurements.
