CONCLUSIONS 



The record number of ioeberfrs driftinf^ into 

 the North Athmtic Ocean in 1!)7'2 was a result 

 of all critical meteorological and oceanographic 

 being favorable foi' such drift prior to and dur- 

 ing the ice season. The single most important 

 factor in this record year was the increased in- 

 tensity of tiie Icelandic Low. This resulted in 

 tlie favorable northwesterly winds carrying 



coldei- than normal air temperatures, which in 

 turn helped produce greater ice cover, lower sea 

 temperatures, and less rainfall. Although the 

 change in the Icelandic Low was the single most 

 important change from the previous season it is 

 notetl that each condition discussed here is neces- 

 saiy for a lecord year. A change in any one 

 would have caused a reduced iceberg county.
