play a major role in the number of icebergs 

 moving southward into the shipping lanes, 

 so that, for example, extensive sea ice leads 

 to numerous icebergs. Edward H. Smith 

 (1926) described sea ice as acting like a 

 fender (others have called it an ice fence) 

 on the shoreward side of the Labrador 

 Current, preventing icebergs from moving 

 close to shore and there grounding, thus 

 allowing them to drift farther south and 

 into the shipping lanes. Sea ice also 

 protects icebergs from wave action — a 

 major source of deterioration — and, of 

 course, signals the presence of cold water, 

 which also slows deterioration. 



Peterson, Prinsenberg, and 

 Langille (2000) explored the relationship 

 between sea ice and iceberg populations. 

 They found that the "annual number of 

 icebergs drifting south of 48°N is most 

 strongly correlated with sea ice extent off 

 Newfoundland between 47 and 52°N from
