icebergs drifted south of 48°00' N. Limits of pack and berg ice were 



less than the average limits shown in the Ice Atlas of the Northern 



Hemisphere. 



JULY 



On July 3, the pack ice had retreated from the eastern entrance 

 of the Strait of Belle Isle, and since only scattered bergs and growlers 

 remained in the strait proper, the passage was considered navigable. 

 Bergs continued a slow southerly movement during the entire month. 

 The most southerly reportings, a growler on July 9 at 48°49' N., 

 44°24' W., and a radar target, possibly a growler, at 48°52' N., 

 45°21' W., on July 25, were on the eastern edge of the Labrador 

 Current in positions vdiich would in all probability insure their 

 drift to the northward, as all three oceanographic surveys had mdi- 

 cated a recurvature of the Labrador Current in that direction north 

 of Flemish Cap. 



On July 28, at the request of Commander, International Ice Patrol, 

 the Coast Guard Air Detachment, Argentia, made a postseason ice 

 observation flight covering the coastal area near Cape Bonavista and 

 the Labrador Current between 50°00' N., and 52°00' N. Numerous 

 bergs and growlers were sighted within a 50-mile radius of 51°00' N., 

 51°00' W., but high surface water temperatures appeared to leave 

 little likelihood that there would be any drift south of 48°00' N. 



Two postseason aerial reconnaissance flights were made during the 

 month. No known icebergs drifted south of 48°00' N. Limits of 

 pack and berg ice were less than the average limits shown in the Ice 

 Atlas of the Northern Hemisphere. 



AUGUST 



Although the southerly drift of most of the bergs reported in July 

 had been halted, some bergs continued their southward movement 

 in the Labrador Current. On August 6, one berg was sighted as far 

 south as 49°32' N., 50°11' W. No sea ice was reported. Four 

 postseason aerial reconnaissance flights were made during the month. 



SEPTEMBER 



Some bergs remained potential threats by continuing to move south- 

 ward. On September 18, several bergs were reported at 49°00' N., 

 49°52' W. This slow southerly movement was completely halted 

 before the end of the month. The last postseason aerial reconnais- 

 sance flight of the year, on September 29, showed that there was no 

 longer any ice below 50°00' N. There were 5 postseason aerial 

 reconnaissance flights in September making a total of 11 such flights 



for the vear. 



OCTOBER-NOVEMBER-DECEMBER 



Icebergs continued to be reported in October, and one large berg 

 was reported as far south as 50°17' N., 49°35' W. on the 22d. The 

 last ice reported in 1952 was a berg in the Belle Isle Straits on 30 

 October.
