Due to poor visibility in the vicinity of Hudson Strait entrance, it is 

 estimated that as many as 25 bergs may have been missed there. Also 

 it is estimated that as many as 100 bergs may have been missed close 

 alongshore from Cape Dyer to Bylot Island. 



On the basis of conclusions from the 1964 preseason northern ice 

 surveys, it was assumed that the 1965 Grand Banks iceberg crop 

 was mostly located at this time in the area from off Cumberland Sound 

 northward along the Baffin Island Coast to about 90 miles offshore to 

 near Devon Island. Assuming that all of the small bergs south of 

 Cumberland Sound would deteriorate before reaching the Grand 

 Banks and discounting all but the larger bergs south of about 58° 

 N., the berg crop for 1965 was estimated to be about 800 bergs at this 

 time, or less than a normal supply. As a result of the preseason north- 

 ern surveys of 1963 and 1964, it was concluded that a normal supply 

 as of early December was about 1,250 bergs. A glance at the berg 

 sizes also indicates a lower potential for 1965, as the sizes are believed 

 generally smaller than normal. There is no doubt that some additions 

 to the berg crop can and will occur directly from the unsurveyed area 

 north and east of Cape Dyer. However, any additions by this route 

 are expected to be more than compensated for by continual deteriora- 

 tion of bergs south of the pack ic« and by some permanent or semi- 

 permanent trappings or other elimination from the current system. 

 It is noted that there was no sea ice south of Cape Henry Kat-er 

 (69° N.), Also the number of bergs south of Cape Chidley was re- 

 duced from 192 on 22 September to 89 on 21 October indicating that 

 the deterioration heavily exceeded the resupply during the interval 

 for the area south of Cape Chidley. During the period 22 September- 

 21 October, bergs drifted about 7 miles per day along the Labrador 

 coast with neutral winds.
