ABSTRACT.
A combination of the directional surveys of the Camp Century borehole from 1966, 1967, 1969 and 1989 has revealed a deformation pattern similar to that measured at Dye-3, South Greenland and Byrd Station, Antarctica showing high deformation rate for Wisconsin ice. Compared to the Dye-3 profile, the deformation shows the same pattern even in details. The surface velocity obtained by integrating the bore hole deformation is in agrement with that obtained from satellite measurements.
