A particle based simulation model for glacier dynamics [PDF]
, 2013 A particle-based computer simulation model was developed for investigating the dynamics of glaciers. In the model, large ice bodies are made of discrete elastic particles which are bound together by massless elastic beams.

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

IceLines – A new data set of Antarctic ice shelf front positions
Scientific Data, 2023 The frontal position of an ice shelf is an important parameter for ice dynamic modelling, the computation of mass fluxes, mapping glacier area change, calculating iceberg production rates and the estimation of ice discharge to the ocean.

Calving cycle of the Brunt Ice Shelf, Antarctica, driven by changes in ice-shelf geometry [PDF]
The Cryosphere, 2019 Abstract. Despite the potentially detrimental impact of large-scale calving events on the geometry and ice flow of the Antarctic Ice Sheet, little is known about the processes that drive rift formation prior to calving, or what controls the timing of these events.

Efficient Location and Extraction of the Iceberg Calved Areas of the Antarctic Ice Shelves
Remote Sensing, 2020 Continuous, rapid, and precise monitoring of calving events contributes to an in-depth understanding of calving mechanisms, which have the potential to cause significant mass loss from the Antarctic ice sheet.

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

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]
, 2008 Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

Tidewater glacier response to individual calving events
Journal of Glaciology, 2022 Tidewater glaciers have been observed to experience instantaneous, stepwise increases in velocity during iceberg-calving events due to a loss of resistive stresses.

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

Brief Communication: Newly developing rift in Larsen C Ice Shelf presents significant risk to stability [PDF]
The Cryosphere, 2015 An established rift in the Larsen C Ice Shelf, formerly constrained by a suture zone containing marine ice, grew rapidly during 2014 and is likely in the near future to generate the largest calving event since the 1980s and result in a new minimum area ...
