By the end of May there was no sea-ice 

 south of Hamilton Inlet, a condition more 

 typical of June 25th, about four weeks ahead 

 of normal. A large population of icebergs in 

 the approaches to the Strait of Belle Isle and 

 northward along the Labrador coast was 

 documented by several PAL flights in May 

 and many reports from the increased 

 transatlantic shipping using the strait after it 

 cleared of sea-ice. No icebergs passed south 

 of 48°N during May. 



June and July 



In Newfoundland and Labrador the 

 record-setting warmth continued in June, 

 with 33 temperature records set or tied 

 (Environment Canada Atlantic Region, 

 2006). The pace of the sea-ice retreat slowed 

 somewhat in June., but the northward 

 movement of the ice edge still remained 



ahead of normal. By the first week of July - 

 about two weeks earlier than normal - sea-ice 

 departed Labrador's coast. 



Throughout June and into early July, 

 a large iceberg population persisted from the 

 Strait of Belle Isle northward along the 

 Labrador coast. Vessels using the Strait of 

 Belle Isle reported numerous icebergs within 

 and on the Atlantic Ocean approaches to the 

 strait. In addition, reconnaissance, primarily 

 by PAL, as well as Canadian ice breakers 

 CCGS Terry Fox and CCGS Pierre 

 Radisson, reported large numbers of icebergs 

 off the Labrador coast during June. On its 30 

 June iceberg-analysis plot CIS was carrying 

 68 1 icebergs and radar targets between 50°N 

 and 56°N. 



After verifying that there were no 

 icebergs threatening the transatlantic 

 shipping lanes, Ice Patrol's last 2006 ice 

 reconnaissance detachment returned from 

 Newfoundland on 20 June.
