when compared, to data olotalned at Station 1, those obtained at 

 Station k on 5^ 6, and 7 November indicate that vertical trans- 

 port of sensible heat -was not a factor in maintenance of the 

 ice-free area adjacent to the pier. The temperature beneath 

 the ice outside the bubbled area was identical to that of the 

 isothermal water column at Station 1. 



Subsequent history of the polynya was similar to that of 

 the previous winter.
