Ice thickness distribution of Himalayan glaciers inferred from DInSAR-based glacier surface velocity

Environmental Monitoring and Assessment, 2022
Retrieval of glacier ice thickness is extremely important for monitoring water resources and predicting glacier dynamics and changes. The inter-annual glacier ice thickness observations (more than 5 years) exploit the glacier mass changes. Ice thickness is one of the important parameters to predict the future sea-level rise.

Measuring glacier velocity

Physics Bulletin, 1987
Whether the Greenland and Antarctic ice sheets are shrinking, growing or in equilibrium has become the subject of current scientific investigations because such changes would be of worldwide importance. For instance, melting of the two ice sheets would cause a rise in sea level of as much as 70 m (R H Thomas et al 1985 NASA Tech. Memo.

Antarctica: Measuring Glacier Velocity from Satellite Images

Science, 1986
Many Landsat images of Antarctica show distinctive flow and crevasse features in the floating part of ice streams and outlet glaciers immediately below their grounding zones. Some of the features, which move with the glacier or ice stream, remain visible over many years and thus allow time-lapse measurements of ice velocities.

21st-Century Evolution of Greenland Outlet Glacier Velocities

Science, 2012
Not So Fast Recent observations of some of Greenland's outlet glaciers have shown large and rapid increases in the speeds at which their ice has streamed to the sea. Simple projections of ice loss and sea level rise, based only on these increases, result in alarmingly high values and correspondingly great public concern. In order

Velocity Changes of Rock Glaciers and Induced Hazards

2014
Recent observations and geodetic measurements in the European Alps show that changes are occurring on rock glacier dynamics, ranging from moderate velocity variations to strong acceleration or even total collapse. These changes can be related to the ground temperature and to climate warming.

Tide-induced perturbations of glacier velocities

Global and Planetary Change, 2007
Abstract Recent observations showing substantial diurnal changes in velocities of glaciers flowing into the ocean, measured at locations far inland of glacier grounding lines, add fuel to the ongoing debate concerning the ability of glaciers to transmit longitudinal-stress perturbations over large distances.

Columbia Glacier, Alaska: Changes in velocity 1977–1986

Journal of Geophysical Research: Solid Earth, 1987
The Columbia Glacier, a grounded, iceberg‐calving tidewater glacier near Valdez, Alaska, began to retreat about 1977. Drastic retreat occurred in 1984, and by early 1986, retreat amounted to 2 km. The glacier has thinned more than 100 m since 1974 at a point 4 km behind the 1974 terminus position.
