| Title: | Measured velocities and ice flow in Wilkes Land, Antarctica / Neal W. Young, I.D. Goodwin, N.W.J. Hazelton, R.J. Thwaites. |
| Author(s): | Young, Neal W. Goodwin, I. D. Hazelton, N. W. J. Thwaites, R. J. |
| Date: | 1989. |
| Publisher: | Cambridge: International Glaciological Society |
| In: | Annals of Glaciology. (1989.), Vol. 12 (1989) |
| Abstract: | Ice velocity, surface elevation, and ice thickness were measured on oversnow traverses along three main transects. Velocity measurements show that ice flow varies smoothly in both direction and magnitude over distance scale of at least 20 times ice thickness and that it is in direction of surface slope averaged over similar distance scale. Comparison of mean horizontal shear strain-rate with driving stress supports power-law relation for bulk rheology of ice sheet with exponent between 3 and 3.2. |
