Guard Cutter Casco to be 220 feet high and 700 feet long. During the 

 next few days, southwesterly surface winds prevailed driving this 

 berg eastward put of the Labrador Current. On 19 June, this berg 

 was sighted at 48°04' N., 46°54' W., well reduced in size and was 

 the only berg east of 51° W. The flight on the 19th also reve.aled 

 about 15 bergs between 51° W. and 52° W. between 48°40' N. and 

 49°10'N. For ice conditions on this date see figure 14. 



A flight on the 21st determined that there were only three bergs 

 east of 53° W., north of 49° N. to 51°30' N. On the basis of the 

 flights of the 19th and 21st and the oceanographic conditions on the 

 Grand Banks as determined by the 3d and 4th surveys by the Ever- 

 green, there was no probable threat to Track C and no likely threat 

 to Track E. Therefore, the services of the International Ice Patrol 

 were terminated on 22 June. 



It is estimated that 10 bergs drifted south of 48° N. during June 

 making a total of 117 bergs for 1962. See figure 18 for the plot of 

 ice sighted and reported during June. 



With predominantly northerly surface winds during June, the pack 

 ice was contained close along shor^ in colder water and persisted 

 longer than usual in the Notre Dame-Belle Isle Straits area. Although 

 the icebreaker U.S. Coast Guard Cutter Westmind was the first ship 

 to make passage through the Belle Isle Strait in the 1962 ice season 

 on 8 June, Belle Isle Strait was not considered navigable by merchant 

 vessels until 14 June when the Topdalsfjord made passage from the
