of the Grand Banks as far south as latitude 45° N. Several bergs were 

 to be found during the whole month along the eastern slope of the banks 

 south of 45° N., off the Tail of the Banks between latitudes 42° N. and 

 43° N., and east of the banks to about longitude 45° W. between the 

 44th and 45th parallels. The most westerly berg position reported in 

 June was 14 miles southwest of Cape St. Mary (27 June), the most 

 southerly position was 41°56' N., 50°03' W. (22 June), and the most 

 easterly was 44°02' N., 44°44' W. (29 June). One berg drifted south 

 along the east slope of the Grand Banks, around the Tail of the Banks 

 and west to 53° W., then north to the 100-fathom curve on the southwest 

 slope of the Banks. The Flemish Cap sector was clear of all ice through- 

 out June. 



Heavy pack ice blocked the eastern approaches to the Strait of Belle 

 Isle during the entire month. 



The distribution of ice reported in June is shown graphically in figure 

 16. 



JULY 



No field ice existed on the Grand Banks in July. On the first of the 

 month field ice extended along the coast of Labrador from the Strait 

 of Belle Isle northward. By the middle of the month the Strait of Belle 

 Isle was free except for heavy berg concentrations, and at the end of the 

 month the southern limits of the field ice had receded to Cape Harrison, 

 Labrador. 



During the first week in July several bergs were located on the Tail- 

 of-the-Banks between latitudes 42° and 43° N., and many bergs were on 

 the northern slope of the Banks above 46° N. and to the east and south 

 of the Avalon Peninsula. The second week was marked by a rapid 

 recession of bergs on the Banks so that by the middle of the month 

 there existed only scattered bergs east of the Avalon Peninsula between 

 47° N. and 48° N. and only one to the south. By the end of the month 

 this recession had continued to such an extent that only the one southern 

 berg remained in the Grand Banks area. Ice conditions for July are 

 shown in figure 17. 



The last mentioned berg which had been aground between 46° N. and 

 47° N. and about 48° W. in a depth of approximately 100 fathoms 

 melted free around the middle of July and commenced a rapid drift to 

 the south, showing that the Labrador Current was still remarkably well 

 defined. The size of this berg as measured by the USS Kirkpatrick 

 using visual and sonic methods, showed it to be block shaped, 125 feet 

 above the waterline, 900 feet long at the surface and extending below 

 the surface to a depth of 600 feet. The end of the month found it at the 

 Tail-of-the-Banks and directly in the effective steamer track "C" (west- 

 bound). The drift of this berg is included in figure 18. 



It is estimated that 113 bergs drifted south of the 48th parallel during 

 July.
