On climatic changes in the temperature of the Barents Sea and their possible causes

Analysis of the monthly average temperature data of the Barents Sea at various depths showed its significant increase over the past decades. Against the background of this growth, temperature fluctuations were detected with periods close to the periods of El Nino – Global atmospheric oscillations, North Atlantic fluctuations and changes in the North Atlantic current. Analysis of daily average temperature data of the Barents Sea surface showed an increase in the amplitude, number and duration of extreme temperature phenomena with a positive sign and a decrease in extreme temperature phenomena with a negative sign for the period of satellite observations
