the number of icebergs estimated to have 

 moved south of 48°N put the year in the 

 extreme category, but, according to the 

 length of season criterion, each year was 

 classified as average. The NSSI for 2003 

 was 2.70 while the 2002 index was 2.80; 

 both in the moderate NSSI rating category. 

 For brief periods, the southern LAKI during 

 both years was south of 40°N. Both had 

 winter (December through March) North 



Atlantic Oscillation Indices that were 

 weakly positive, 0.20 in 2003 and 0.76 in 

 2002 (Hurrell, 2004). There was one 

 significant difference between the two 

 years. For most of 2002, the eastern LAKI 

 was farther east than normal, and during 

 part of June was near the eastern extreme. 

 On the other hand, the 2003 eastern limit 

 hovered at or less than the median for the 

 entire ice season.
