STUDIES OF ICE MOVEMENTS ON THE WARD HUNT ICE SHELF BY MEANS OF TRIANGULATION-TRILATERATION
A method is described by which accurate measurements of ice movements were performed on the Ward Hunt Ice Shelf at Ward Hunt Island. Geodimeter distance measurements and angular theodolite measurements were combined in a system of triangulation-trilateration in the form of a chain of quadrilaterals...
