Large-scale investigation into iceberg-tsunamis generated by various iceberg calving mechanisms [PDF]

open access: yesCoastal Engineering, 2021
Abstract Mass balance analysis of ice sheets is a key component to understand the effects of global warming with iceberg calving as a significant contributor. Calving recently generated tsunamis of up to 50 m in amplitude endangering human beings and coastal infrastructure.

BREAK OUT OF A-76 ICEBERG AND RECENT DYNAMIC CHANGES OF ITS ENCOLSURE RIFTS IN RONNE ICE SHELF, ANTARCTICA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Monitoring the stability of the Ronne Ice Shelf, particularly the calving event, is an integral and important part of the study of Antarctic ice sheet mass balance and sea-level rise. This paper presents the results of the analysis of the world’s largest

Automated ArcticDEM iceberg detection tool: insights into area and volume distributions, and their potential application to satellite imagery and modelling of glacier–iceberg–ocean systems [PDF]

open access: yesThe Cryosphere, 2023
Iceberg calving accounts for up to half of mass loss from the Greenland Ice Sheet (GrIS), with their size distributions providing insights into glacier calving dynamics and impacting fjord environments through their melting and subsequent freshwater ...

Fragmentation theory reveals processes controlling iceberg size distributions

open access: yesJournal of Glaciology, 2021
Iceberg calving strongly controls glacier mass loss, but the fracture processes leading to iceberg formation are poorly understood due to the stochastic nature of calving.

Identification of iceberg-forming ice quakes from seismic and infrasound data

open access: yesЛëд и снег, 2021
The application of a joint method of recording seismic and infrasound signals generated during ice calving from the terminal part of the outlet glaciers to identify the process of iceberg formation is considered.

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.

Two Calving Laws for Grounded Iceberg-Calving Glaciers (Abstract only) [PDF]

open access: yesAnnals of Glaciology, 1983
Prediction of the future retreat of Columbia Glacier, Alaska, required a calving law for the boundary condition at the terminus. Qualitative observations on the variations of all major iceberg-calving glaciers of Alaska suggest that calving is high whenever glaciers terminate in deep water, and greatly reduced whenever they terminate in shallow water ...

Automatic delineation of cracks with Sentinel-1 interferometry for monitoring ice shelf damage and calving [PDF]

open access: yesThe Cryosphere, 2022
Monitoring the evolution of ice shelf damage such as crevasses and rifts is important for a better understanding of the mechanisms controlling the breakup of ice shelves and for improving predictions about iceberg calving and ice shelf disintegration ...

SYNOPTIC OBSERVATIONS OF CALVING EVENTS IN ANTARCTICA USING SPACEBORNE IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Iceberg calving is the detachment of ice from ice shelves or glaciers. Although calving is a natural phenomenon, an abnormal rate of calving can be a threat to ice shelves.

Parameterizing Tabular‐Iceberg Decay in an Ocean Model

open access: yesJournal of Advances in Modeling Earth Systems, 2022
Large tabular icebergs account for the majority of ice mass calved from Antarctic ice shelves, but are omitted from climate models. Specifically, these models do not account for iceberg breakup and as a result, modeled large icebergs could drift to low ...
