MARC recordCharacterizing englacial drainage in the ablation zone of the Greenland ice sheet / Ginny A. Catania, Thomas A. Neumann, Stephen F. Price.
| Title: | Characterizing englacial drainage in the ablation zone of the Greenland ice sheet / Ginny A. Catania, Thomas A. Neumann, Stephen F. Price. |
| Author(s): | Catania, Ginny A. Neumann, Thomas A. Price, Stephen F. |
| Date: | 2008. |
| In: | Journal of Glaciology. (2008.), Vol. 54(187) (2008) |
| Abstract: | Reports use of ice-penetrating radar surveys at base of Greenland ice sheet to characterise englacial drainage features that appear as vertically stacked diffraction hyperbolae in common-offset profiles. Data are used with radar-simulation model (which allows for variations in geometry, penetration depth and infill material) to understand characteristics of hyperbolae and likelihood that they are produced by moulins. Finds only moderate correlation between locations of possible moulins and supraglacial lakes, indicating that many lakes drain over surface of ice sheet, or do not contain sufficient water to reach bed through moulin formation. |
