Island. In other words, the air temperature very closely followed the temperature of the under- 

 lying water surface. 



Also worthy of attention are the very high water temperatures, up to 10.6°. Taking into 

 consideration the early season of the year, and also the existence of an ice dam in the mouth of the 

 Yeniseiski Gulf, we must assume that such high temperatures are only partly due to the heat of the 

 coastal current but are mainly created locally by the combined influence of solar radiation and 

 advective heat of the atmosphere . It is clear that if such warm water is subsequently blown by the 

 wind onto ice, there will then result a stronger washing-away of projecting edges of ice. If the wind 

 starts to drive the ice into such warm water the small floes will completely disappear and the large 

 floes be considerably destroyed. As has already been remarked, this accounts for the influence of 

 pol3myas and open water on the melting of ice.
