Figure 174. Drift p/x Soroka from 16 December 1941 to 8 January 1942 

 and the trawler T-60 from 1 to 5 January 1942. 



Figure 175 shows the averaged isobars from 1 through 5 January 1942. We find a very good 

 coincidence of isobar directions and drift directions. It must only be emphasized that such a con- 

 currence of directions of drifts and isobars results from the fact that the ice, in the course of its 

 drift along the isobars, did not encounter obstacles (shores, islands and fast ice). 



If we examine carefully the drift of the trawler T-60, we see that the ice moved not only 

 under wind influence, but also under influence of the tidal currents, describing closed curves for 

 the most part clockwise. In order to exclude the effect of tidal phenomena, let us take a portion of 

 the drift from 00 hours on 2 January to 0230 on 4 January, comprising 50 hours, or in other words.
