OCEANOGRAPHIC OPERATIONS 



Two oceanographic cruises were conducted in 

 support of the International Ice Patrol during the 

 1969 ice season. The oceanographic information 

 that was collected was used to forecast the drift of 

 ice. The U.S. Coast Guard Cutters Chincoteague 

 and Cook Inlet conducted these oceanographic op- 

 erations during the periods 2-28 April 1969 and 14 

 May to 9 June 1969 respectively. 



The oceanographic data collected on the two 



cruises revealed, under preliminary operational 

 analysis, that the cm-rent structure of the Grand 

 Banks did not vary greatly from the noiinal How- 

 ever, water temperatures appeared generally 

 warmer than normal. For a detailed discussion of 

 the oceanography of the region of the Grand 

 Banks during the 1969 ice season, refer to the 

 appropriate USOG Oceanographic Report (CG 

 373 series) .
