RADAR DETECTION OF FLOATING ICE 



1946 ICE SEASON 



Hand in hand with the work of the International Ice Patrol in 

 keeping track of the ice which each year threatens the steamer 

 tracks of the North Atlantic has gone the development and applica- 

 tion of new methods of scouting and detecting the ice. During the 

 war years, including the ice seasons of 1942 through 1945, there 

 was no International Ice Patrol. However, the United States 

 Atlantic Fleet conducted an ice information service for the benefit 

 of Allied naval and merchant shipping. The naval needs and uses

 requirements of peacetime and the ice information service was 

 altered to meet these changing conditions with the facilities avail-
