eluded that with normal favorable winds from November to June, 

 bergs north of Cape Dyer can make it to the Grand Banks by late 

 April or early May. Therefore an early November survey should 

 extend north to Cape Christian. It is believed that an early De- 

 ember survey need extend only to Cape Dyer. 



6. Nearly all the bergs located along the Labrador coast in mid- 

 January arrived at the Grand Banks. Meteorological conditions 

 averaged favorable for south drift and favorable for berg survival 

 due to average northwest cold air circulation over the area from mid- 

 January to early April. Unless there is significant permanent strand- 

 ing of bergs en route to the Grand Banks from the Labrador coast, 

 berg attrition is very low in the winter months. The pack ice is 

 probably an important factor here in acting as a buffer to keep bergs 

 from stranding and also preserving the bergs by maintenance of 

 cold temperatures and reduction of wave erosion. 



7. The percentage of available bergs entering Hudson Strait in the 

 autumn and winter months may have a considerable influence on 

 the forthcoming Grand Banks berg season. The Marion expedition 

 in 1929 indicated that a branch of the Baffin Land Current entered 

 northern Hudson Strait, recurving near Big Island and flowing out 

 the southern side to rejoin the main branch now designated the Lab- 

 rador Current. Tidal currents and average winds also undoubtedly 

 have a considerable effect on the percentage of bergs entering Hudson 

 Strait. It is plausible that during some years a considerable portion 

 of the berg crop might be destroyed by being driven into Hudson Strait 

 and permanent stranding by prevailing easterly winds as the crop 

 approaches Hudson Strait entrance. Little evidence on hand sup- 

 ports the theory that most of the bergs entering Hudson Strait will 

 eventually drift out through the southern entrance. Canadian 

 Department of Transport flights over the past few years indicate 

 that there are about three times as many bergs in northern Hudson 

 Strait as in southern Hudson Strait, with considerable stranding along 

 the southern Baffin Island coast. The northern surveys in January 

 and March 1963 and subsequent ice observation indicated that almost 

 all of the 1963 crop has drifted south from Davis Strait across the 

 entrance of Hudson Strait to Labrador without taking the detour 

 into Hudson Strait. 



8. An estimated 13 percent of the bergs located from Hudson Strait 

 entrance to Cape Dyer in early November 1961 drifted south of 48° N. 

 in 1962. For the 1963 season, an estimated 3 percent of the bergs from 

 Hudson Strait entrance to Cape Dyer in early November 1962 drifted 

 south of 48° N. These percentages are believed less than normal due 

 to average unfavorable meteorological conditions for berg drift south and 

 berg survival both years. It is estimated that about 25 percent of the 

 berg crop located from Cape Chidley to Cape Dyer in early November 

 will drift south of 48° N. under normal meteorological conditions during
