Quasi-static granular flow of ice mélange [PDF]
, 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]
Annals 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]
The 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 ...

Intermittent structural weakening and acceleration of the Thwaites Glacier Tongue between 2000 and 2018 [PDF]
, 2020 Evolving conditions at the terminus of Thwaites Glacier will be important in determining the rate of its future sea-level contribution over the coming decades.

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

Crevasse advection increases glacier calving
Journal of Glaciology, 2022 Iceberg calving, the process where icebergs detach from glaciers, remains poorly understood. Moreover, few parameterizations of the calving process can easily be integrated into numerical models to accurately capture observations, resulting in large ...

Calving cycle of Ninnis Glacier over the last 60 years
International Journal of Applied Earth Observations and Geoinformation, 2021 Iceberg calving is one of the contributing ways for the mass loss from ice shelves in Antarctica; the calving cycles of most ice shelves are quite long.

A unifying framework for iceberg-calving models [PDF]
Journal of Glaciology, 2010 AbstractWe propose a general framework for iceberg-calving models that can be applied to any calving margin. The framework is based on mass continuity, the assumption that calving rate and terminus velocity are not independent and the simple idea that terminus thickness following a calving event is larger than terminus thickness at the event onset. The
