July 



The iceberg condition in the begining of July, as shown 

 in figure 20, still had 76 icebergs south of A8°N. With 

 four radar targets at the Tail of the Banks, the Surface 

 Patrol continued until the fog lifted and subsequent searches 

 by the Coast Guard cutter failed to locate any ice. Thus on 

 10 July, with icebergs no longer a threat south of 44°N, the 

 Surface Patrol was terminated. Intermittent ice observation 

 flights throughout the month, limited due to on scene weather, 

 monitored the retreating iceberg limits. Then on 25 and 26 

 July flights with very good visibility failed to locate any 

 icebergs. The four icebergs on figure 21 were reported by a 

 ship subsequent to the 26 July flight and were the only 

 icebergs remaining in the vicinity of the Grand Banks to 

 threaten North Atlantic shipping. These bergs subsequently 

 drifted south of 48°N before melting during the first week 

 of August. Thus notification was given the maritime community 

 and Ice Patrol services ended on 31 July. During this month 

 an estimated 19 additional icebergs drifted south of 48°N. 



August 



Although the Ice Patrol services had officially terminated, 

 the Ice Season terminates on 31 August for statistical purposes 

 with the new season begining 1 September. During the remainder 

 of the month many iceberg reports were received from ships 

 approaching the Strait of Belle Isle, the southernmost of which 

 were two icebergs located just south of 51°N on 28 August. One 

 berg drifted south of 48°N during August which brought the 

 statistical total for the 1973 season to 847 icebergs (plus 3 

 which were left over from the 1972 season).
