Observations on Athabaska Glacier and their relation to the theory of glacier flow
2011The objects of the present study were to collect adequate data concerning the distribution of velocity in a typical valley glacier, to relate these to current theories of glacier flow, and if necessary to suggest modifications to these theories. Conventional field methods were used.

Ice‐deformation in the flow of glaciers
Eos, Transactions American Geophysical Union, 1941Under a project‐grant from the Geological Society of America, thin‐section studies were made of ice from the glaciers of Mt. Rainier. Of greatest interest were observations of ice‐granules along and across “fault‐planes” in the glaciers. In many of the cases observed no true fracture or movement on discrete planes seems to have occurred.

Fast glacier flow: Ice streams, surging, and tidewater glaciers
Journal of Geophysical Research: Solid Earth, 1987Fast flowing glaciers are unusual but important. Jakobshavns Glacier in western Greenland illustrates this point (Figure 1). Considered to be the world's fastest glacier, its maximum observed flow rate (measured in midsummer near the floating terminus) is 8360 m yr−1 [Lingle et al., 1981].

Flow instabilities of Alaskan glaciers
2014Over 300 of the largest glaciers in southern Alaska have been identified as either surge-type or pulse-type, making glaciers with flow instabilities the norm among large glaciers in that region. Consequently, the bulk of mass loss due to climate change will come from these unstable glaciers in the future, yet their response to future climate warming is

Accurate modelling of glacier flow
2010Recent interest in climatic change and ice .sheet variations points out the need for accurate and numerically stable models of time-dependent ice masses. Little attention has been paid to this topic by the glaciological community, and there is good reason to believe that much of the published literature on numerical modelling of the flow of glaciers ...
