Using ice - flow models and observations, the researchers, led by Ian Joughin of the University of Washington, concluded:

The glaciological community has for decades harbored the widespread belief that the thermal evolution of the ice sheet, and the effect of this evolution on ice flow, are central in the ice - age cycling (not all communities agree, but there is plenty of literature on this from the land - ice crowd), so use of a temperature - independent rheology for the ice leaves out one favored explanation for termination of extensive glaciation.

Advances in glacier ice flow mapping using repeat satellite images, and later using interferometric synthetic aperture radar SAR methods, facilitated the mass budget approach, although this still requires an estimate of snow input and a cross-section of the glacier as it flows out from the continent and becomes floating ice.
