51°30'W), no iceberg reports were received in 

 June after the 4th. All ice south of 48°N was 

 calculated to have melted in mid-June, but with- 

 out visual confirmation that all of the icebergs 

 previously spotted south of Newfoundland had 

 totally disintegrated, the Ice Patrol service con- 

 tinued. Finally a break in the weather occurred 

 on 20 and 21 June. Two flights provided con- 

 firmation that no ice existed south of 47°30'N. 

 One small iceberg with growlers had drifted 

 south and grounded off St. John's during the 

 third week of June but it presented no threat to 

 the Grand Banks. With this information and 

 knowledge that the upstream iceberg population 

 was sparse and had little potential of producing 

 a berg that would reach 47°N, notice was given 

 to the maritime community that International 

 Ice Patrol services would be terminated on 23 

 June. The Ice Patrol Reconnaissance Detach- 



ment returned to the United States on that date. 

 It was estimated that a total of 5 icebergs crossed 

 48° N during June. 



July-August 



No more icebergs were known to have drifted 

 south of 48°N during July or August. The total 

 count of icebergs crossing 48 °N for 1975 was 101. 

 Although a number of sightings continued to be 

 reported to the Ice Patrol during the summer, 

 most were located just east of the Strait of Belle 

 Isle. One exception was a group of bergs sighted 

 between 48°34'N-48°49'N and 48°33'W-49°05'W. 

 These were resighte.d again slightly further south 

 on 8 August, In July only belts and strips of sea 

 ice existed off the Labrador coast and the only 

 concentrated pack was off Baffin Island between 

 62°N and 72°N. By mid-August, this entire area 

 was free of sea ice.
