the years 1891, 1892, 1893 and 1906 a remarkable accumulation of icebergs appeared 

 in the area south of Cape Horn and northward of the Falkland Islands as far as 40° S. 

 They occurred mainly along the edge of the shelf; farther to the west they were com- 

 pletely absent. They are trapped and melt rapidly inside the numerous eddies along 

 the boundary between the Falklands Current and the Brazil Current in a similar way 

 to those south of the Newfoundland Banks. 



(e) Seasonal and Aperiodic Variations in Iceberg Frequency off Newfoundland 



Surveillance of the distribution of icebergs in the area of the Newfoundland Banks 

 since 1900 has given the mean annual iceberg frequency and its variation from month 

 to month shown by the data in Table 108 for Newfoundland (south of 48° N.) and 

 for the area south of the Grand Banks.
