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

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

A Monte-Carlo error analysis for basal sliding velocity calculations [PDF]
, 2006 Since glacier beds are mostly inaccessible, numerical inversion of the surface velocity field provides a valuable method for calculating the basal shear stress and sliding velocity. However, previous theoretical studies (limited either to planar slabs or

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

Electronic Measurement of Ice Velocity [PDF]
Journal of Glaciology, 1971 Abstract A light-weight solid-state electronic distance meter was used to measure short-term ice velocities during a two-day interval on the Coleman Glacier at Mt Baker, Washington, U.S.A. The velocities fluctuated rapidly from zero or almost zero to a large fraction of a meter per day.

Warm ocean is eroding West Antarctic Ice Sheet [PDF]
, 2004 Satellite radar measurements show that ice shelves in Pine Island Bay have thinned by up to 5.5 m yr^{-1} over the past decade. The pattern of shelf thinning mirrors that of their grounded tributaries-the Pine Island, Thwaites and Smith glaciers- and ...
