Size and thickness of drift ice belong to basic parameters which determine design and operation of oil and gas producing facilities offshore of the northern Sakhalin. Drift ice appears on the northern Sakhalin offshore in November--December and disappears in May--June. Maximum development of ice cover falls on March--April. Under the influence of constant East-Sakhalin current sea ice drifts southwards and covers the distance from northern regions of Sakhalin (Yelizaveta Cape) to the Kuril Islands within 20--30 days. Multiyear aerial ice reconnaissance data were analyzed which involved winter seasons of the entire severity range. The most severe winter seasons within the analyzed time period occurred in 1957, 1966, 1985 and 1988. Hence, the results given in this paper describe basic regularities for seasonal variability of sea ice size and thickness and may be considered as reliable climatic characteristics for the region under discussion.
