Ice Velocity Mapping of Ross Ice Shelf, Antarctica by Matching Surface Undulations Measured by ICESat Laser Altimetry [PDF]

open access: yesRemote Sensing of Environment, 2012
We present a novel method for estimating the surface horizontal velocity on ice shelves using laser altimetrydata from the Ice Cloud and land Elevation Satellite (ICESat; 20032009). The method matches undulations measured at crossover points between successive campaigns.

Ice Surface Velocity in the Eastern Arctic from Historical Satellite SAR Data [PDF]

open access: yes, 2022
Abstract. Knowledge on ice surface velocity of glaciers and ice caps contributes to a better understanding of a wide range of processes related to glacier dynamics, mass change and response to climate. Based on the recent release of historical SAR data from various space agencies we compiled nearly complete mosaics of winter ice surface velocities for ...

Surface mass balance, ice velocity and near-surface ice temperature on Qaanaaq Ice Cap, northwestern Greenland, from 2012 to 2016 [PDF]

open access: yesAnnals of Glaciology, 2017
To better understand the processes controlling recent mass loss of peripheral glaciers and ice caps in northwestern Greenland, we measured surface mass balance (SMB), ice velocity and near-surface ice temperature on Qaanaaq Ice Cap in the summers of 2012–

Antarctic Surface Ice Velocity Retrieval from MODIS-Based Mosaic of Antarctica (MOA) [PDF]

open access: yesRemote Sensing, 2018
The velocity of ice flow in the Antarctic is a crucial factor to determine ice discharge and thus future sea level rise. Feature tracking has been widely used in optical and radar imagery with fine resolution to retrieve flow parameters, although the ...

Relationship of surface elevation changes of the Antarctic ice sheet with ice movement and subglacial water flow

open access: yesЛëд и снег, 2015
The article provides phenomenological and experimental arguments that ice sheet surface fluctuation in Antarctica is mediated by ice velocity and subglacial water flow.

Surface velocity fields of active rock glaciers and ice‐debris complexes in the Central Andes of Argentina [PDF]

open access: yesEarth Surface Processes and Landforms, 2020
Rock glaciers and transitional ice‐debris complexes predominate the Central Andean landform assemblage, yet regional studies on their state of activity and their kinematics remain sparse.

Surface velocity and mass balance of Ice Streams D and E, West Antarctica

open access: yesJournal of Glaciology, 1996
AbstractOver 75 000 surface-velocity measurements are extracted from sequential satellite imagery of Ice Streams D and E to reveal a complex pattern of flow not apparent from previous measurements. Horizontal and vertical strain rates, calculated from surface velocity, indicate that the bed experiences larger basal shear where the surface of these ice ...

Surface velocity and mass balance of Livingston Island ice cap, Antarctica [PDF]

open access: yesThe Cryosphere, 2014
The mass budget of the ice caps surrounding the Antarctica Peninsula and, in particular, the partition- ing of its main components are poorly known. Here we approximate frontal ablation (i.e.

ICE FLOW VELOCITY MAPPING IN GREENLAND USING HISTORICAL IMAGES FROM 1960s TO 1980s: SCHEME DESIGN [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Ice flow velocity over long time series in Greenland plays a vital role in estimating and predicting the mass balance of the Greenland Ice Sheet and its contribution to global sea level rise.
