May 



Only once during May, on the 9th, was the Patrol able to obtain 

 good aerial reconnaissance south of 47-30N. This flight observed 

 no icebergs north or east of the 50-fathom contour of the Grand 

 Banks. Flights to the north located a concentration of 47 bergs 

 between 49-OON and 50-OON which extended from 51-OOW to 52-OOW on 

 the 3rd. This group was relocated on the 11th in a less compact 

 arrangement which extended from 48-30N to 50-OON and westward from 

 49-OON to the Newfoundland Coast. This large group was never 

 resighted, but the drift computations and aircraft and ship radar 

 reports indicate that the bergs in the eastern portion of this group 

 drifted southeasterly until their remains were scattered within a 

 100-mile radius of Flemish Cap by the 26th. An estimated 20 bergs 

 drifted south of 48-OON during the month. The southernmost sighting 

 occurred on 31 May when a ship reported two icebergs at 46-17N 

 48-25W. The month's easternmost sighting was reported on 11 May at 

 48-20N 45-15W. It is estimated that this iceberg drifted east to 

 49-14N 42-09W before melting. The iceberg drift plot carried the 

 month's southernmost berg to an estimated position of 45-50N 

 47-45W on 8 May. Winds during the month were unfavorable for 

 southerly drift over the Grand Banks and Flemish Cap area. 



Figures 10 and 12 describe the results of aerial reconnaissance and 

 ship reports during the period 6-14 and 24 - 31 May, respectively. 

 Figures 9 and II show the estimated ice situations on 1 and 15 May, 

 respectively. 



June 



The month of June began with the two bergs reported on 31 May 

 as the only known ice south of 48-OON. This situation continued 

 until 21 June when 3 icebergs and a large number of radar targets 

 were reported by a ship near 47-05N 51-30W. These bergs were not 

 sighted by our aircraft while flying over this area on 19 June nor 

 were they relocated by aerial reconnaissance over this area on 24 

 and 26 June and they were presumed melted on the 27th. By 29 June, 

 when Ice Patrol services for the season were terminated, the 

 estimated limit of all known ice had retreated to the northwest. 

 The limits in the final Bulletin were reported as extending from 

 the Newfoundland Coast at 48-lON to 48-lON 46-30W to 48-30N 46-30W 

 and then northwestward. It is estimated that only seven icebergs 

 drifted south of 48-OON during June. Figure 13 depicts the results 

 of reconnaissance and ship sightings during the period 14 - 21 June.
