July 



Reports of icebergs sighted north of latitude 50° became less 

 frequent as the month wore on, until by the end of July, only 

 an occasional berg was sighted in the eastern approaches to 

 the Strait of Belle Isle. 



The second week in July, however, saw several small bergs, 

 survivors of the southward onslaught during June, drift to between 

 48° and 49° north latitude. One of these reached to position 

 46°48'N. 47°46 , W. where, on the 18th, it was last sighted as a 

 growler and melting rapidly. This last report was the only known 

 iceberg which drifted south of the 48th parallel during 1958. 

 That berg and other ice conditions for July are shown on figure 12. 



August-December 



Occasional bergs and growlers were reported off the eastern 

 entrance to the Strait of Belle Isle up to 21 August and none 

 were reported after that date. 



Vessels using the Hudson Bay steamer route to Port Churchill 

 reported scattered bergs along the Labrador coast and rather light 

 ice conditions in general. The Canadian Ice Information Officer 

 also reported that ice conditions along that route were extremely 

 favorable. 



Reports of icebergs and storis ice off Cape Farewell continued 

 throughout the year indicating possible heavier-than-average con- 

 ditions. However, in late summer and along the East Greenland 

 coast, the pack edge receded exceptionally far to the northward 

 and bergs were sighted in Denmark Strait at unusual distances 

 off the Greenland Coast. 



During the summer of 1958 a transatlantic aircraft reported a 

 giant floe or iceberg several hundred miles eastward of Ireland. 

 Investigation by British authorities revealed that the observation 

 was made under difficult conditions and by an inexperienced 

 observer. The report was established to be an oil slick.
