Zhichkin Dynamics of Inter-annual and Seasonal Anomalies of Ice-cover Extent in the Barents and Kara Seas The paper examines results of studies on inter-annual and seasonal fluctuations of sea-ice anomalies in the Barents Sea from 1934 to 2014 and in the Kara Sea from 1979 to 2014. Based on an electronic database of inter-annual data on the sea-ice regime of the Barents Sea, homogenous periods with a prevailing sign of the anomaly are determined, and features of seasonal fluctuations of anomalies in the periods of the maximum (February - April) and minimum (August - September) sea ice-cover extent on the Barents Sea are identified. The ice-cover extent in the Kara Sea in the winter months during the last 10 years was stable, and anomalies of both signs were insignificant. The February 2012 was the most anomalous of the winter months in the Kara Sea, when the ice-cover extent anomaly dropped sharply to - 20 %. During the winter of 2013, under the changing conditions of the largescale atmospheric circulation in the northern hemisphere, the ice-cover extent tended to increase in the Barents and Kara Seas. In the Kara Sea in February-March, this parameter was close to average values. The paper introduces temporal distribution and repeatability of large and super large sea ice-cover anomalies in the Barents Sea within the last 50 years and in the Kara Sea from 1979 to 2012. Keywords: Barents Sea, Kara Sea, sea ice-cover anomalies, inter-annual and seasonal fluctuations. Author Aleksandr P.
