Record #212333:

Mapping and interpretation of bed-reflection power from a surge-type polythermal glacier, Yukon, Canada / Nat J. Wilson, Gwenn E. Flowers, Laurent Mingo.

Title: Mapping and interpretation of bed-reflection power from a surge-type polythermal glacier, Yukon, Canada / Nat J. Wilson, Gwenn E. Flowers, Laurent Mingo.
Author(s): Wilson, Nat J.
Flowers, Gwenn E.
Mingo, Laurent.
Date: 2014.
In: Annals of Glaciology. (2014.), Vol. 55(67) (2014)
Abstract: Uses radar data collected in 2008-11 from surge-type polythermal glacier in St Elias Mountains, Yukon, Canada, to compute bed-reflection power (BRP) and examine its relationship to ice thickness, apparent bed slope, and thickness of englacial scattering layer as proxy for internal reflection power. Then analyses corrected form of BRP with graph-segmentation algorithm to delineate high and low reflection power, and relates to hydrological and thermal conditions in sections of glacier, permitting more accurate assessment of subglacial conditions.
