Abstract
We present the first winter estimates of the Greenland and Barents Seas ice age composition using the ice charts for the period from 1997 to 2022 compiled by the Arctic and Antarctic Research Institute (AARI). The interannual variations in the ice amount of different age categories in it relative fractions in the Greenland Sea and the Barents Sea do not show significant linear trends. When comparing the estimates, obtained in this study, with previous studies on this subject, we may state that quantitative changes in the Greenland and Barents Seas ice age composition began earlier than 1997. Only on the basis of data on the ice age composition over a 25-year long period of observations analyzed in this study, it is impossible to draw a clear conclusion about a decrease in its thickness in the Greenland and Barents Seas.
