August 1987: The retreat of 

 the sea ice edge to just north of 

 Frobisher Bay in August left 

 Hudson Strait and most of Davis 

 Strait ice free (Figure 22). 

 There were 57 icebergs re- 

 ported south of 52°N in August: 

 2 of these were south of 48°N. 



September 1987: The only 

 sea ice observed south of 65° N 

 in September was near Fro- 

 bisher Bay (Figure 23).
