3D Velocity Time Series Inversion of Petermann Glacier Using Ascending and Descending Sentinel-1 Images

Remote Sensing
Three-dimensional (3D) glacier velocities capture the full dynamic behavior of ice masses. For marine-terminating glaciers, acquiring 3D velocity fields is particularly critical for quantifying ice discharge into the ocean, assessing the stability of ...

Characterizing the May 2015 Karayaylak Glacier surge in the eastern Pamir Plateau using remote sensing

Journal of Glaciology, 2016
We investigate an internal surge of Karayaylak Glacier, which was reported by the media in May 2015. To differentiate the May 2015 glacier surge from other glacier advances, we surveyed changes in velocity, crevasses and glacier area using Landsat 8 OLI ...

High-Temporal-Resolution Three-Dimensional Glacier Velocity Time Series and Their Implications for Glacier Dynamic Processes in Mt. Tomur, Tian Shan

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
High-temporal-resolution three-dimensional (3-D) glacier velocity measurements are essential for unraveling complex ice dynamics, enabling precise monitoring of climate-driven glacier response.

Thinning-induced glacier deceleration in the Zanskar Himalayas [PDF]

The Cryosphere
Trends in surface velocity provide insight into glacier response to climate change as well as local drivers of ice dynamics. The Zanskar Himalayas are heavily glacierised, and retreating glaciers pose a threat to local and regional water security ...

Surface Ice Velocity near the Terminus of Grey Glacier in the Southern Patagonian Icefield, Based on Direct Field Measurements

Geosciences
Glacier mass balance and ice flow dynamics, strongly influenced by climatic variability, topography, and geological–structural controls, can be precisely characterized through in situ GPS measurements of surface ice velocity, though such data remain ...

Glacial lakes control ice flow: new insights from satellite SAR PO-SBAS observations in Duiya Glacier, southern Tibetan Plateau

International Journal of Digital Earth
This study investigates the effects of glacial lakes on the flow velocities of Duiya Glacier, southern Tibetan Plateau, by employing satellite Synthetic Aperture Radar (SAR) Pixel-Offset-Tracking Small-Baseline-Subset (PO-SBAS) technology. Duiya Glacier,

The equilibrium flow and mass balance of the Taku Glacier, Alaska 1950–2006 [PDF]

The Cryosphere, 2008
The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat.

Spatial model of the Trooz Glacier dynamics based on meteorological data from the Akademik Vernadsky station

Український антарктичний журнал
This paper models the dynamics of the Trooz Glacier, Antarctic Peninsula. To integrate remote and meteorological data, we processed ice flow velocities derived from satellite radar imagery, air temperature, and precipitation obtained from the ERA5 ...

Distinct characteristics and mechanisms of two tidewater glaciers exhibiting velocity anomalies in western Svalbard

GIScience & Remote Sensing
Svalbard hosts numerous tidewater glaciers whose dynamic responses are critical to polar environmental change and global sea-level rise. This study investigates Tunabreen glacier and Osbornebreen glacier in Svalbard using multi-source remote sensing data

Utilising seismic station internal GPS for tracking surging glacier sliding velocity

Journal of Glaciology
Glacier ice flux is a key indicator of mass balance; therefore, accurate monitoring of ice dynamics is essential. Satellite-based methods are widely used for glacier velocity measurements but are limited by satellite revisit frequency.
