| Title: | Variations in shear deformation rate with depth at Dome Summit South, Law Dome, East Antarctica / Vin Morgan, Tas D. van Ommen, Alan Elcheikh, Jun Li. |
| Author(s): | Morgan, Vin. van Ommen, Tas D. Elcheikh, Alan. Li, Jun. |
| Date: | 1998. |
| In: | Annals of Glaciology. (1998.), Vol. 27 (1998) |
| Abstract: | Shear deformation rate with depth for Dome Summit South (DSS), East Antarctica, is calculated by repeated borehole inclination measurements. Down to 1000 m deformation rates increase as expected, below this depth strain rates decrease. Spike 14 m thick in zone of retarded flow has shear rate 5 times that of surrounding ice, corresponding to ice deposited in Last Glacial Maximum. Surface velocity agrees with value from global positioning system (GPS) |
