to 53°10' N., 50°38' W., with three bergs within a 10-mile radius 

 of 53°10' N., 50°40' W. On February 11, the Coast Guard Air 

 Detachment, Argentia, scouted the northern slopes of the Grand 

 Banks and determined that the southern limit of the pack ice was 

 defined by an irregular line running from Cape Bonavista, Newfound- 

 land, to 51°20' N., 50°20' W. Two bergs were also sighted on this 

 flight, one at 51°45' N., 51°49' W., and the other at 51°53' N., 

 51°02' W. 



The first flights by a regularly assigned International Ice Patrol 

 plane were made on February 16 and 17, and covered the area from 

 Newfoundland east to 45°00' W., between 47°00' N., and 49°00' N. 

 No ice was sighted on either of these flights. Two more flights by 

 Ice Patrol aircraft were made on February 24 and 25, covering the 

 area between 48°00' N., and 51°00' N., from 48°00' W., to New- 

 foundland. The latter of these two flights determined that the 

 southern limit of pack ice ran from Cape Bonavista, Newfoundland, 

 to 49°00' N., 52°00' W., and thence northerly, with ice grading from 

 open pack to consoUdated pack about 30 miles to the west of this 

 line. A total of eight bergs and six growlers were sighted on these 

 two flights between 49°00' N., and 51°30' N., west of 52°00' W. 

 Four bergs and one growler were sighted within a 20-mile radius to 

 the eastward of Cape Bonavista, Newfoundland. The southernmost 

 piece of ice sighted on either of these flights was a very small growler 

 at 48°20' N., 51°56' W. 



On February 26 the S. S. Finn Trader reported three growlers at 

 48°16' N., 50°16' W. This later turned out to be the most southerly 

 ice reporting of the month. Two more bergs were reported on the 

 27th and 28th of the month, the first by the U. S. C. G. cutter 

 Barataria at 48°46' N., 50°59' W., and the second by the U. S. C. G. 

 cutter AlcCulloch at 49°00' N., 50°52' W. 



On February 28, an International Ice Patrol plane en route from 

 Halifax, Nova Scotia, to Argentia scouted the Cabot Strait area 

 and reported the results directly to the Canadian Department of 

 Transport. On a course from Scatari Island to St. Paul Island and 

 thence to Argentia no ice was sighted except close inshore at St. Ann 

 Bay. 



Four flights by regularly assigned International Ice Patrol aircraft 

 were made dming the month, in addition to the scouting done while 

 en route over the Cabot Strait area. No loiown icebergs drifted 

 south of 48°00' N. dm-ing the month. Limits of pack ice 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 1. 



MARCH 



Flights on the 1st of March and the 5th, 6th, and 7th, covering the 

 area from 47°00' N., to 52°00' N., between 46°00' W., and the east
