Measuring glacier velocity

By Alex Hyde Why is understanding glacier velocity important? In the Himalayas, and world-wide, climate change is driving glacier retreat. In some mountain regions like the Himalayas, this climate change is also resulting in large scale changes in glacier ice-flow dynamics and velocity (1-2), which is impacting glacier response to climate change. Measuring these changes … Read more

Structural glaciology

Introduction | Primary stratification | Longitudinal surface structures | Crevasses | Ogives | Debris cover | Medial moraines | Further reading | References | Comments | Introduction As glaciers flow, they crack and fracture in predictable ways. This brittle failure of the glacier ice yields insights into glacier strain, both in the present day and … Read more
