ABSTRACT 



In 1968, three cruises in operational support of the International Ice 

 Patrol were conducted in April, May, and June off the Grand Banks of 

 Newfoundland by the USCGC EVERGREEN. In addition, a section was 

 occupied across the Labrador Sea from South Wolf Island, Labrador to 

 Cape Farewell, Greenland by the USCGC EASTWIND in October 1968. 

 The data obtained were used to draw temperature and salinity profiles, and 

 to calculate surface dynamic topography and geostrophic velocity through 

 the sections. Dynamic calculations were based on a reference level of 1000 

 decibars for the cruises in operational support of the International Ice 

 Patrol and 1500 decibars for the Labrador Sea occupation. Contoured sec- 

 tions and the station data are presented. A sharp increase observed in the 

 transport of the Labrador Current through Section A3 on the eastern slope 

 of the Grand Banks is related to an initial decrease in density of the water 

 column below 200 meters. Volume, salt, and heat transports through the 

 Labrador Sea section are presented.
