Internal ice-sheet radar layer profiles and their relation to reflection mechanisms between Dome C and the Transantarctic Mountains / Martin J. Siegert, Shuji Fujita.
Title: | Internal ice-sheet radar layer profiles and their relation to reflection mechanisms between Dome C and the Transantarctic Mountains / Martin J. Siegert, Shuji Fujita. |
Author(s): | Siegert, Martin J. Fujita, Shuji. |
Date: | 2001. |
In: | Journal of Glaciology. (2001.), Vol. 47(157) (2001) |
Abstract: | Investigates layered internal reflections in radar sounding data from Antarctic Ice Sheet. Uses similarities in Scott Polar Research Institute (SPRI) and the better calibrated Japanese Antarctic Research Expedition (JARE) data to re-interpret SPRI data for information on internal reflection mechanisms. Identifies particular form of A-scope profile (returned power against depth) associated with changes in ice permittivity with depth. Argues that below a certain depth these arise from changes in crystal-orientation rather than density. Finds this mechanism dominant cause of internal reflection at depths below 1000 m in the marginal area and associates it with large strains induced by shearing ice flow. |
