considered. This possibility was discarded as the December survey 

 had a real good look at Hudson Strait and Frobisher Bay entrance 

 and there was no indication of a heavy movement of bergs into this 

 area since late October. 



3. The berg supply south of Cape Dyer (252 bergs; 121 S, 103 M, 

 28 L) was noticeably less than the supply determined in this area 

 December 1963 (532 bergs; 174 S, 227 M, 131 L) in both total amount 

 of bergs and in sizes. It is estimated that the autumn climate in this 

 region was about normal. Assuming that the 1964 supply w^as slightly 

 less than normal, it is obvious that the 1965 supply is less than one-half 

 a normal supply. Accordingly, if normal climatology prevails this 

 winter and spring, less than half a normal amount of icebergs are 

 expected to drift south of 48° N. 



4. The southern pack ice limits were located near Cape Chidley. 

 The eastern limits extended about 60-70 miles offshore of Baffin Island. 

 There was some slush ice close along the Labrador coast in protected 

 waters as far south as 53°30' N. The pack ice off Baffin Island was 

 estimated to be less extensive in coverage and thinner than it was in 

 December of 1963. 



5. The first group of bergs expected to be a factor on the Grand 

 Banks in 1965 are presently located in the vicinity of Hudson Strait 

 entrance. A few of the medium bergs, presently close ashore between 

 58° N. and Cape Chidley, may drift free and join the first group. 

 The first group was believed located between 63°30' N. and Cape Dyer 

 on 22 October and drifted at an average rate of 5.3 miles per day since 

 then under unfavorable winds and spent considerable time aground. 



6. The second recognizable concentration was centered near 64° N., 

 62° W. and was believed located well offshore and northeast of Cape 

 Dyer on 23 October. This group traveled at an average rate of 6.7 

 miles per day and possibly spent a little time aground. It is entirely 

 possible that this second group came directly across upper Davis Strait 

 from the Disko Bay glaciers during the late summer and early autumn 

 as winds favored westerly drift in this area during this time. 



7. There was a large concentration of bergs, over 2,000, about 150 

 miles southwest of Melville Bay on 23 October. There w^ere no other 

 large concentrations found during this survey. Winds averaged 

 slightly onshore at Melville Bay during July, August, and September. 

 The pack ice conditions there in September were known to be very 

 bad and apparently the pack ice failed to drift west and clear the 

 area as usual. It is concluded that the same fate befell the Melville 

 Bay 1964 berg crop and that this large concentration was mostly Mel- 

 ville Bay origin. This large concentration is not believed capable of 

 reaching the Grand Banks during the 1965 ice season as it is probably 

 a couple of hundred miles too far removed even if conditions for drift 

 and survival to the Grand Banks were abnormally favorable. The
