Velocity response of Petermann Glacier, northwest Greenland, to past and future calving events [PDF]

open access: yesThe Cryosphere, 2018
Dynamic ice discharge from outlet glaciers across the Greenland Ice Sheet has increased since the beginning of the 21st century. Calving from floating ice tongues that buttress these outlets can accelerate ice flow and discharge of grounded ice. However,

Quasi-static granular flow of ice mélange [PDF]

open access: yes, 1936
We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier.

Automatic Extraction of the Calving Front of Pine Island Glacier Based on Neural Network

open access: yesRemote Sensing, 2023
Calving front location plays a crucial role in studying ice–ocean interaction, mapping glacier area change, and constraining ice dynamic models. However, relying solely on visual interpretation to extract annual changes in the calving front of ice ...

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.

A Law for Small Scale, Continuous Calving [PDF]

open access: yes, 2014
Ice shelves are formed by the viscous flow of inland ice into the ocean, they are floating and loosing mass by iceberg calving. There are two different kinds of calving: large tabular icebergs detach as singular events in time, and small scale calving ...

Modeling of the northern hemisphere ice sheets during the last glacial cycle and glaciological sensitivity [PDF]

open access: yes, 2005
We present a new three-dimensional thermomechanically coupled ice sheet model of the northern hemisphere to reconstruct the Quaternary ice sheets during the last glacial cycle.

Dynamic jamming of iceberg-choked fjords [PDF]

open access: yes, 2014
We investigate the dynamics of ice mélange by analyzing rapid motion recorded by a time-lapse camera and terrestrial radar during several calving events that occurred at Jakobshavn Isbræ, Greenland. During calving events (1) the kinetic energy of the ice

Centurial‐millenial ice‐rafted debris pulses from ablating marine ice sheets [PDF]

open access: yes, 2001
We use an ice‐sheet model to show that (i) margins of marine ice‐sheets can be expected to be frozen to the bed, except where ice‐streams discharge; (ii) 20–50km retreats induced by ablation rates of 2 m/yr provide sufficient debris flux through the ...

On The Calving of Ice From Floating Glaciers and Ice Shelves [PDF]

open access: yesJournal of Glaciology, 1968
The deformation and the state of stress in the frontal part of a floating glacier is analysed by a method analogous with the beam theory, applied in engineering practice for determining stresses and deflections of a beans of an elastic material. Very rough approximations are made, the most severe being that of assuming the viscosity of the ice constant.

Calving rates at tidewater glaciers vary strongly with ocean temperature [PDF]

open access: yes, 2015
TerraSAR-X data were provided by DLR (project OCE1503), and funded by the Conoco Phillips-Lundin Northern Area Program through the CRIOS project (Calving Rates and Impact on Sea level). A.L. and S.B.
