Studies of Ice Movements on the Ward Hunt Ice Shelf by Means of Triangulation-Trilateration

Ward Hunt Island is surrounded by more than 2000 sq km of ice shelf. In 1964 and 1965 the University of New Brunswick Department of Surveying Engineering made a survey of the ice shelf in which geodimeter distance measurements and angular theodolite measurements were combined in a system of triangul...
