On a basis of the analysis of archived ice charts for 1997–2017 calculations of changes in the stages of sea ice development composition in southwest part of the Kara Sea during the autumn and winter period are executed. The obtained data allowed establishing the changes in quantity (area) and corresponding thicknesses with 10 days discretization for all stages of sea ice development and the periods of their prevalence from the beginning till the end of ice formation. The essential distinctions between the stages of ice development composition for drifting and fast ice exhibiting in an earlier appearance and different relative quantity of the first year ice within the fast ice zone are revealed. Such studies were not performed earlier. Its results supplement ice conditions characteristics southwest in the part of the Kara Sea during the “warm” climatic period.
