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.

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.

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.

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 ...

Velocity variability of Devon Ice Cap tidewater glaciers
2014Tidewater outlet glaciers drain approximately 47% of the ~105,000 km^2 covered by ice caps in the Queen Elizabeth Islands of Nunavut, Canada, suggesting that iceberg discharge may be an important process in the mass balance of these ice caps. Seasonal and inter-annual velocity changes of tidewater glaciers may result in the misestimation of annual or ...

Seismic Wave Velocities in the Hans Glacier, Spitsbergen
2013Direct measurements of P and S wave velocities were performed by a special seismometer array on the Hans Glacier, in the vicinity of the Polish Polar Station Hornsund, Spitsbergen. Artificial quakes were generated at a point of central location between the seismometer sites. The calculated velocities are: VP = 3,620 m/s, VS = 1,780 m/s.
