The siirface temperatiire at Station ID, located immediately outside 

 the bubbler field, shows that the surface water had cooled to the 

 freezing point. Despite ice formation around the perimeter of the agita- 

 ted area, the data obtained at Station 1 show the surface temperature to 

 be 0.67° C above the freezing point. The data for Station ID are assumed 

 to be indicative of temperature data that would have been observed at 

 Station 1 had the bubbler system not been in operation. The data of 13 

 October plus the profiles for Stations 2 and 3 on 12 October indicate 

 that water from depths greater than 15 meters is circulated into the 

 agitated water columns adjacent to the pier. 



Proof that the bubble system acts as a huge pump capable of perform- 

 ing work on the surrounding subsurface water is provided by comparison 

 of data presented in Tables II and III.
