Does englacial water storage drive temperate glacier surges?

Structural control of englacial conduits in the temperate Matanuska Glacier, Alaska, USA

Fourteen englacial conduits were mapped within 2 km of the terminus of the temperate Matanuska Glacier, Alaska, USA, to ice depths of 65m using speleological techniques. Detailed threedimensional maps of the conduits were made over 3 years to characterize conduit relationships with glacier structural features and to track conduit evolution through time. All conduits consisted of single unbranch...

A Theory of Glacier Surges

We propose a model of glacier flow for at least a hundred years, and a major conthat is capable of explaining temperate glacier ference (see Canadian Journal of Earth Sciences, surges. The laws of conservation of mass and vol. 6, pp. 807-1018, 1969) was devoted to their momentum are supplemented by the prescription study. Meier and Post [1969] summed up many of of a sliding law that gives the b...

A Mathematical Analysis of Glacier Surges

This paper describes the phenomena of glacier surges and presents a mathematical model based on realistic descriptions of glacier physics, which purports to describe the main features of the flow. The analysis reveals and predicts a variety of phenomena, many of which have been observed to occur, and gives explicit estimates for such quantities as surge front extent, "mini-surge" propagation sp...

Snow Avalanches, Ice Avalanches and Glacier Surges

The concept of glacier storage: a review

Glacier storage is a widely used term, applied to different processes and time-scales by different disciplines in hydrology and glaciology. We identify that storage occurs as ice, snow, and water associated with three time-scales. Long-term storage concerns storage of ice and firn as glaciers on time-scales of years to centuries and longer. This storage affects global sea level and long-term wa...
