Continent‐Wide, Interferometric SAR Phase, Mapping of Antarctic Ice Velocity
Geophysical Research Letters, 2019 Surface ice velocity is a fundamental characteristic of glaciers and ice sheets that quantifies the transport of ice. Changes in ice dynamics have a major impact on ice sheet mass balance and its contribution to sea level rise.

Surface velocity and ice thickness of the Müller ice cap, Axel Heiberg Island
, 2021 Muller ice cap is situated on Axel Heiberg Island in Arctic Canada. It is characterised by a mountanious region separating the ice cap in the east from the outlet glaciers in the west. Research has taken place on the outlet glaciers of the ice cap since 1959, but only limited research has been conducted on the main ice cap, and no full depth ice cores ...

Inverting ice surface elevation and velocity for bed topography and slipperiness beneath Thwaites Glacier [PDF]
The Cryosphere, 2021 There is significant uncertainty over how ice sheets and glaciers will respond to rising global temperatures. Limited knowledge of the topography and rheology of the ice–bed interface is a key cause of this uncertainty as models show that small changes in the bed can have a large influence on predicted rates of ice loss.

ICE FLOW VELOCITY MAPPING OF EAST ANTARCTICA FROM 1963 TO 1989 [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Long-time serial observation of surface ice flow velocity in Antarctic is a crucial component in estimating the mass balance of Antarctic ice sheet. However, there is a lack of historical continental scale velocity maps of Antarctica before the 1990s ...

Measuring temperature of the ice surface during its formation by using infrared instrumentation [PDF]
, 2007 A non-destructive remote sensing technique was used to measure the surface temperature of a thin macroscopic water film flowing on a growing asymmetric ice accretion during its formation inside an icing research wind tunnel.

Constraining subglacial processes from surface velocity observations using surrogate-based Bayesian inference [PDF]
Journal of Glaciology, 2020 Basal motion is the primary mechanism for ice flux in Greenland, yet a widely applicable model for predicting it remains elusive. This is due to the difficulty in both observing small-scale bed properties and predicting a time-varying water pressure on ...

Journal of Glaciology, 2020 Glacier ice thickness is crucial to quantifying water resources in mountain regions, and is an essential input for ice-flow models. Using a surface velocity inversion method, we combine ice thickness measurements with detailed surface elevation and ...

A Combined Approach for Filtering Ice Surface Velocity Fields Derived from Remote Sensing Methods [PDF]
Remote Sensing, 2017 Various glaciological topics require observations of horizontal velocities over vast areas, e.g., detecting acceleration of glaciers, as well as for estimating basal parameters of ice sheets using inverse modelling approaches. The quality of the velocity is of high importance; hence, methods to remove noisy points in remote sensing derived data are ...
