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.

An exploration of volcanic controls on glacier velocity
2023Approximately 17% of the Earth’s 1,413 Holocene volcanoes are glacier covered or possess at least one glacier within a radius of 5 km. Glacier-volcano interactions are therefore relatively common, yet our understanding of these interactions is hindered by a sparsity of observations and a lack of quantitative data.

The Application of GPS in Glacier Flow Velocity: A Case Study of Qiyi Glacier
Applied Mechanics and Materials, 2011Surface flow velocity is a key parameter of glacier kinetic theories study. With the help of GPS, glacier surface flow velocity research improved convenient and accurate. Therefore, this paper is committed to acquire the condition of surface flow velocity of Qiyi Glacier during 2009 to 2010 based on GPS data, optical remote sensing images and ...

21st-Century Evolution of Greenland Outlet Glacier Velocities
Science, 2012Not 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

Observations of Small Deviations in Glacier Velocity Measurements
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008As part of the international IPY project GLACIODYN (the dynamic response of Arctic glaciers to global warming) the velocity of the Kronebreen glacier at Svalbard was measured testing an interferometric radar with high range and high temporal resolution.

Antarctica: Measuring Glacier Velocity from Satellite Images
Science, 1986Many 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.

Glacier surface velocity measure based on polarimetric tracking
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012The contribution of Polarimetric Synthetic Aperture Radar (PolSAR) images compared with the single-channel SAR in terms of temporal scene characterization has been found and described to add valuable information in the literature. Recently, a new PolSAR tracking algorithm has been proposed for glacier surface velocity monitoring.

Tide-induced perturbations of glacier velocities
Global and Planetary Change, 2007Abstract 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.

Ice thickness distribution of Himalayan glaciers inferred from DInSAR-based glacier surface velocity
Environmental Monitoring and Assessment, 2022Retrieval 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.
