ABSTRACT 



The air-bubbling teciinique utilized by the Military Sea 

 Transportation Service to prevent ice formation in North Star 

 Bugt, Thule, Greenland is discussed. A proposed model of 

 induced water circulation is presented. Physical processes 

 impeding ice formation and growth in sea water are described. 

 Oceanographic data collected in conjunction with the MSTS 

 project are analyzed and presented in the appendixes.
