Publication Dates: 1961, 19645 1966, 1968), L971, 1972, and 1975 
Location: The number of ice stations selected for ice 
observation varies from year to year. They are 
widely distributed to cover lakes, rivers, and 
coastline of Alaska and Canada. As of 1972, a 
total of 46 stations were located in Alaska and 
43 in Canada.
