ABSTRACT 



Results of oceanographic surveys off the Grand Banks of Newfoundland 

 from April thi-ough June 1972 in support of International Ice Patrol and 

 twelve occupations of Standard Sections A1-A4 are discussed. Analysis 

 includes vertical temperature and salinity profiles for each section as well as 

 dynamic-topographic charts for eacli Ice Patrol survey. Normal dynamic 

 topography charts of the Grand Banks region are updated. Results are 

 similar to those obtained by Soule (1964). Finally there is a discussion of 

 the oceanograpliic and meteorological conditions which caused more icebergs 

 to drift south of 48°N in 1972 than in any previous year in Ice Patrol liistory. 

 These conditions include iceberg supply, wind, currents, waves/sea ice, sea 

 temperatures, air temperatures, and precipitation. It is concluded that the 

 single most important factor effecting these conditions is the location and 

 intensity of the Icelandic low.
