Review ice charts of the Arctic Ocean are posted here.  
Scale of hardcopy corresponds to 1:10000000. 
During summer period (1.VI-30.IX) charts depict distribution of generalized categories of sea ice total concentration 
for the intervals 1-6/10s and 7-10/10s, during winter period (1.XI-31.V) - distribution of 
generalized sea ice stages of development (ice thickness) - nilas, young, first-year and old ice. 
Data collection (averaging) is done for preceding 2-5 days interval. 
Ice charts are issued every Thursday. Ice charts are based on automatical generalization of regional 
ice charts which are compiled on a basis of analysis of satellite (visible, infra-red and radar) information and reporets from coastal stations and ships.
