'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 ...

Apparent Short-Term Glacier Velocity Variations [PDF]

open access: yesJournal of Glaciology, 1985
AbstractIn connection with a glacier-hydrological project at a sub-polar glacier in West Greenland, short-term glacier velocity variations were measured. Both the horizontal and the vertical velocity components showed distinct diurnal variations. Close examination indicates that these variations are caused by the change in atmospheric refraction during

The dynamics of Trooz Glacier, Antarctic Peninsula, by satellite remote sensing data

open access: yesУкраїнський антарктичний журнал, 2023
The paper studies the ice cover of the Trooz Glacier, Kyiv Peninsula, West Antarctic Peninsula. The main goal of the work is to study the velocity dynamics of various parts of the Trooz Glacier in 2016–2022 based on remote sensing data and to compare ...

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]

open access: yes, 2012
We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Glacier dynamics near the calving front of Bowdoin Glacier, northwestern Greenland [PDF]

open access: yes, 2015
To better understand recent rapid recession of marine-terminating glaciers in Greenland, we performed satellite and field observations near the calving front of Bowdoin Glacier, a 3 km wide outlet glacier in northwestern Greenland.

Climatic control on seasonal variations in mountain glacier surface velocity [PDF]

open access: yesThe Cryosphere, 2023
Abstract. Accurate measurements of ice flow are essential to predict future changes in glaciers and ice caps. Glacier displacement can in principle be measured on the large scale by cross-correlation of satellite images. At weekly to monthly scales, the expected displacement is often of the same order as the noise for the commonly used satellite images,

Inversion of Glacier 3D Displacement from Sentinel-1 and Landsat 8 Images Based on Variance Component Estimation: A Case Study in Shishapangma Peak, Tibet, China

open access: yesRemote Sensing, 2022
Offset tracking technology is widely studied to evaluate glacier surface displacements. However, few studies have used a cross-platform to this end. In this study, two heterogeneous data sources, Sentinel-1 and Landsat 8, from January 2019 to January ...

Land- to lake-terminating transition triggers dynamic thinning of a Bhutanese glacier [PDF]

open access: yesThe Cryosphere, 2022
There have been rapid increases in both the number and expansion of the proglacial lakes across High Mountain Asia. However, the relationship between proglacial lakes and glacier dynamics remains unclear in the Himalayan region.

MAPPING SURFACE FLOW VELOCITIES OF SIACHEN AND GANGOTRI GLACIERS USING TERRASAR-X AND SENTINEL-1A DATA BY INTENSITY TRACKING [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Glaciers are melting at an alarming rate due to global warming. Two major glaciers of India viz. Gangotri and the Siachen are chosen for the velocity mapping. The line-of-sight (LOS) velocity fields are derived using X-band TerraSAR-X and C-band Sentinel-
