the last ice report of the year was issued by the Canadian Department 

 of Transport and all routes to the St. Lawrence were reported clear 

 for navigation except via the Strait of Belle Isle. 



Nine aerial surveys were made by Ice Patrol aircraft during May. 

 It is estimated that two bergs came south of 48°00' N. during the 

 month, but that none drifted south of 47°00' N. Limits of pack 

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

 of the Northern Hemisphere. Distribution of ice is shown in figure 4. 



JUNE 



On the 1st day of the month a flight was made to search the east 

 coast of Newfoundland from Cape St. Francis north, and the area from 

 Belle Isle east to 50°00' W. Scattered bergs and growlers were found 

 along the coast from Cape Bonavista to Fogo Island, and also in the 

 vicinity of Funk Island. The pack ice blocking the eastern entrance 

 to the Strait of Belle Isle was found to be deteriorating rapidly, al- 

 though many bergs and growlers were still held in the ice, which was 

 limited by a line running approximately from Hare Bay, Newfound- 

 land, to 52°00' N., 54°00' W., thence north. Some loose strings of 

 ice were found to eastward of this line, and many bergs and growlers 

 in the vicinity of 52°00' N., 51°30' W. The most southerly ice 

 sighted on this flight, which was far enough out in the Labrador Cur- 

 rent to make possible a further movement into the more heavily 

 traveled areas, were a berg and two growlers near 51°45' N., 51°30' W., 

 and a radar target, evaluated as a growler, at 51°42' N., 50°40' W. 



A flight on June 6, under conditions of better visibility, found the 

 pack ice limits essentially the same, with the exception that the band 

 of ice blocking the Strait of Belle Isle extended south to the Gray 

 Islands. Fewer bergs and growlers were found in the previously well 

 populated area near 52°00' N., 51°30' W., although two small growlers 

 were sighted near 51°15' N., 49°50' W., indicating further southerly 

 movement of the ice sighted on June 1. 



The last ice observation flight of the season was made on Jmie 12, 

 with poor visual conditions prevailing. Pack ice in the Belle Isle area 

 had further receded, and was now bounded by a line from the Gray 

 Islands to 52°15' N., 54°30' W., with the more northerly extension 

 not determined. Bergs in the Labrador Current east of Belle Isle 

 had practically disappeared except for two radar targets, probably 

 growlers, at 50°30' N., 48°10' W. 



Since rapid deterioration of ice was apparent, and because of the 

 seasonal advance of warmer air and increasing water temperatures, 

 it was considered very unlikely that any ice could survive the journey 

 to the Grand Banks. Consequently, Ice Patrol services for the year 

 were termmated on June 16. Ice reports during the remainder of the 

 month indicated little change in the conditions previously described. 



Three ice observation flights were made during the first 2 weeks of 

 the month before Ice Patrol services were concluded. No known
