Figure 173 shows the distribution of ice in the White Sea from air reconnaissance made on 

 17 February 1942. These ice conditions were created as a result of south and southeast winds which 

 prevailed over the White Sea from about 25 January, when a strong anticyclone prevailed with its 

 center over the Ural region and affecting a great part of European USSR. 



Starting 27 January, the icebreaker Lenin had the same task as for the period from 12 

 through 18 January--to bring out vessels stuck in the ice of Dvlna Bay. What had been very difficult 

 for the Lenin from 12 through 18 January was easily accomplished over the period 29 January to 

 4 February. During this period the icebreaker reached 65° 36' north, 39° 05' east. 



From these examples we may see what an effect the wind has on the distribution of ice in the 

 basin of the White Sea and its bays, and to what extent navigation of even powerful icebreakers in 

 this sea is affect by the winds . 



Figure 174 shows the drift of the steamship Soroka (solid line), from 16 December 1941 

 from the fast ice at Molotovsk to 8 January 1942 at 66° 09' north, 41° 00' east. Also the drift of 

 the trawler T-60 (dotted line) from 1 through 5 January 1942, going from 65° 52' north, 38° 45' 

 east to 67° 06' north, 41° 30' east. Both of these drifts, one along the Zimni shore and the other 

 along the Terski shore, occurred with south winds.
