Record #211511:

Glacier volume estimation as an ill-posed inversion / David B. Bahr, W. Tad Pfeffer, Georg Kaser.

Title: Glacier volume estimation as an ill-posed inversion / David B. Bahr, W. Tad Pfeffer, Georg Kaser.
Author(s): Bahr, David B.
Pfeffer, W. Tad.
Kaser, Georg.
Date: 2014.
In: Journal of Glaciology. (2014.), Vol. 60(223) (2014)
Abstract: Discusses nature of ill-posed problem and how this applies to estimations of glacier volume, which depend on inferring properties at depth e.g. bed topography or basal slip, from properties observed at surface e.g. area and slope, creating instability that can corrupt thickness and volume calculations. Examines scaling and numerical techniques to eliminate instability, and discusses their limitations.
