APRIL 



Eighty-nine different bergs were sighted and reported during April. 

 A few of these were situated just north of the Grand Banks, but the 

 great majority were located in the cold current off the eastern edge 

 of the Grand Banks east and west of a line from 49° 00' N., 45° 00' W., 

 to 42° 00' N., 50° 00' W. 



One small berg was followed southeastward from the Grand Banks 

 until it melted 100 miles east of the Tail. Late in the month a start 

 was made in following the drift of three large bergs. Reference to 

 the ice map for May will show that two of these bergs had extraor- 

 dinarily long drifts which carried them across the "B" tracks. No 

 field ice was reported from south of the forty-eighth parallel during 



April. 



MAY 



The majority of May's 101 bergs were located north of the Grand 

 Banks along the Cape Race, or "F" traffic lanes. For the first time 

 in 1930 numerous bergs were reported from close to the Newfoundland 

 coast. This gradual shifting westward of the southward-moving 

 stream of bergs is a prominent feature of the approaching end of the 

 berg season for the "A," "B," "C," and "D" traffic lanes. Ice drifts 

 south of the Tail are prevented by this westward tendency of the bergs 

 fully as much as by their melting under the influence of the vernal 

 increase in temperature of the surface water. 



East of the Grand Banks there were some scattered reports of 

 bergs from a very large area. By May 24 it was possible to complete 

 the drift tracks of the three southernmost bergs. One of these tracks 

 was started on April 18 and the other two began on April 22. The 

 longest of the three tracks was about 550 sea miles in length . The 

 berg which followed this route was under surveillance for 32 days. 



JUNE 



It is estimated that 62 different bergs were reported from south of 

 the forty-eighth parallel during June. All of these were located 

 between Cape Race and a point 80 miles northwest of Flemish Cap. 

 A great majority of the bergs were within 60 miles of the Newfound- 

 land coast. 



The cold stream off the eastern edge of the Grand Banks was abso- 

 lutely free from ice. The scattered bergs that had been in it during 

 May melted before June 1 . The withdrawal of the threat of ice from 

 the "A," "B," "C," and "D" traffic lanes occurred earlier than has 

 been the case for many yeare.
