The southernmost iceberg for the month drifted to 41-36N 48-46W on 

 22 June. By the end of the month the sea ice had gradually receded 

 to SON and consisted of open to close pack melting first year ice in the 

 central pack and very open pack ice elsewhere. The limits of all 

 known ice were then as shown in figure 16 with 133 icebergs on plot 

 south of A8N. The southernmost 23 bergs had been located by a flight 

 on 28 June. During June it is estimated that 225 icebergs drifted 

 south of 48N as compared to 40 in a normal year. 



July 



In early July the sea ice consisted of rapidly disintegrating open 

 to very open pack ice north of SON. By 9 July the Strait of Belle Isle 

 was open to maritime traffic and the ice pack had receded to 54N on 

 11 July. With a dominant wind from the southwest, the large concentration 

 of icebergs located in June between SON and 52N never drifted south of 49N. 

 This wind also continued to generate a constant fog over the Grand Banks 

 making reconnaissance flights next to impossible. Throughout the month, 

 weekly flights were conducted south of the Tail of the Banks to update the 

 southernmost iceberg positions. On 17 July another flight between SON and 

 S2N showed 1476 bergs distributed between the coast and 48W. Fog persisted 

 for almost the entire month between 43N and SON, but partially abated during 

 the last week so that a series of flights could be flown in this area. The 

 tracks covered on 26, 27 and 29 July are shown in figure 17. By the end 

 of July, an estimated 48 icebergs had drifted south of 48N. The limits of 

 all known ice are shown in figure 18.
