Discussion 



The 2005 ice season saw 1 1 

 icebergs pass south of 48°N, tying 1924 

 as the sixth-mildest ice year in Ice 

 Patrol's history. 



There were no clear and 

 consistent early-season indicators for the 

 low iceberg count. The usual indicators 

 of ice-season severity — preseason iceberg 

 surveys, development of sea ice along the 

 Labrador and Newfoundland coasts, and 

 the North Atlantic Oscillation (NAO) 

 index — offered mixed signals. 



Both the October 2004 iceberg 

 census conducted by CIS in Davis Strait and 

 the combined IIP and PAL flights in late 

 January and early February gave evidence 

 that there were few icebergs upstream of 

 48°N. The CIS census found 10 icebergs in 

 the offshore area, while the IIP and PAL 

 patrols detected 1 1 icebergs, all north of 

 54°N. The results of these early flights 

 confirmed that the prediction of a late start 

 to the iceberg season (Desjardins, 2004) was 

 correct and pointed to a light upcoming 

 iceberg season. It is almost certainly a 

 coincidence, however, that the number of 

 icebergs found in the preseason surveys (10 

 and 1 1 ) and the total 2005 iceberg count 

 (11) were nearly the same. Nevertheless, the 

 message from the surveys was clear: a light 

 season was imminent. 



On the other hand, sea-ice 

 development in Newfoundland and Labrador 

 waters was near normal during freeze-up in
