Specific Features of Iceberg Distribution According to Shipborne Observations in the Kara Sea in 2004-2019

Abstract

The analysis of ship observations on the location and characteristics of icebergs according to shipborne observations in the Kara Sea from 2004 to 2019 is presented. Distribution of the frequency of occurrence of particular shapes and sizes of icebergs are shown and comparison with the climatic long-term data is presented. Frequencies of iceberg occurrence were estimated for the areas of the Franz Josef Land and Severnaya Zemlya archipelagoes for the ice regime of the Arctic of the last decades. Isolated icebergs observed near the long-term mean southern boundary of icebergs' propagation distribution, have been identified for the area where the probability of iceberg occurrence is less than 1%.
