determinations and conclusions of berg characteristics were made. 

 (For a full discussion of these surveys, see another section of this 

 bulletin.) The average drift rate of bergs along the Labrador coast 

 in the winter and spring of 1962 and 1963 was about 7.5 miles per day. 

 Using an average drift rate of 7.5 miles per day along the Labrador 

 coast and somewhat less along the Baffin Island coast, it can be con- 

 cluded that bergs north of Cape Dyer in early December are ordi- 

 narily unable to reach the Grand Banks prior to late June or July 

 and most likely will not survive the trip. One of the conclusions was 

 that assuming average meteorological and oceanographic conditions, 

 bergs must drift south past Cape Chidley from early November 

 through February in order to have much chance of making it to the 

 Grand Banks prior to deterioration. The location of the first con- 

 centration of bergs appears to support this conclusion. Since the 

 total of 532 bergs counted is less than the estimated 900 bergs in this 

 region in early November 1961 and the estimated 850 in 1962, it can 

 be concluded that the berg potential for 1964 on the Grand Banks is 

 well below normal, for both 1962 and 1963 were light ice years. How- 

 ever, it should be noted that the berg sizes were much larger than those 

 surveyed before the 1963 season, and there were considerably more 

 bergs (124) along the Labrador coast than the 20 counted there in 

 mid- January of 1963. At any rate the 1964 Grand Banks iceberg year 

 is forecast to be lighter than normal.
