Discovery of the Fastest Ice Flow along the Central Flow Line of Austre Lovénbreen, a Poly-thermal Valley Glacier in Svalbard

open access: yesRemote Sensing, 2019
Ice flow velocity is a sensitive indicator of glacier variations both controlling and representing the delivery of ice and affecting the future stability of ice masses in a warming climate.

Overestimation and adjustment of Antarctic ice flow velocity fields reconstructed from historical satellite imagery [PDF]

open access: yesThe Cryosphere, 2022
Antarctic ice velocity maps describe the ice flow dynamics of the ice sheet and are one of the primary components used to estimate the Antarctic mass balance and contribution to global sea level changes. In comparison to velocity maps derived from recent

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]

open access: yes, 2010
The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Experimental and numerical modeling of high speed ice impact onto rigid target [PDF]

open access: yes, 2015
The core goal of this research is to develop an ice impact modelling methodology for ice impact on aircraft structures. The main current limitation of ice impact analysis is the ice constitutive model, so this research is focussed on the assessment and ...

Seven-year variation in glacier surface velocity at Narsap Sermia in Southwest Greenland

open access: yesGIScience & Remote Sensing, 2023
Glacier velocity is a critical factor closely related to ice dynamics of the Greenland ice sheet (GrIS). We present variations of ice velocity using space-based synthetic aperture radar (SAR) observations from July 2013 to September 2020.

Short-term variability in Greenland Ice Sheet motion forced by time-varying meltwater inputs: implications for the relationship between subglacial drainage system behavior and ice velocity. [PDF]

open access: yes, 2012
High resolution measurements of ice motion along a 120 km transect in a land-terminating section of the GrIS reveal short-term velocity variations (<1 day), which are forced by rapid variations in meltwater input to the subglacial drainage system from

Dynamics of Dalk Glacier in East Antarctica Derived from Multisource Satellite Observations Since 2000

open access: yesRemote Sensing, 2020
Monitoring variability in outlet glaciers can improve the understanding of feedbacks associated with calving, ocean thermal forcing, and climate change.

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]

open access: yes, 2005
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Numerical Investigation of the Pressure Drop Characteristics of Isothermal Ice Slurry Flow under Variable Ice Particle Diameter

open access: yesJournal of Chemistry, 2020
Ice slurry is an advanced secondary refrigerant that has been attracting considerable attention for the past decade due to the growing concerns regarding energy shortage and environmental protection. To stimulate the potential applications of ice slurry,

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]

open access: yes, 2007
A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...
