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.

Calving seismicity from iceberg–sea surface interactions [PDF]
Journal of Geophysical Research: Earth Surface, 2012 Iceberg calving is known to release substantial seismic energy, but little is known about the specific mechanisms that produce calving icequakes. At Yahtse Glacier, a tidewater glacier on the Gulf of Alaska, we draw upon a local network of seismometers and focus on 80 hours of concurrent, direct observation of the terminus to show that calving is the ...

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

A glacier–ocean interaction model for tsunami genesis due to iceberg calving [PDF]
Communications Earth & Environment, 2021 AbstractGlaciers calving icebergs into the ocean significantly contribute to sea-level rise and can trigger tsunamis, posing severe hazards for coastal regions. Computational modeling of such multiphase processes is a great challenge involving complex solid–fluid interactions.

Buoyant forces promote tidewater glacier iceberg calving through large basal stress concentrations [PDF]
The Cryosphere, 2019 Iceberg calving parameterisations currently implemented in ice sheet models do not reproduce the full observed range of calving behaviours. For example, though buoyant forces at the ice front are known to trigger full-depth calving events on major ...

Effect of topography on subglacial discharge and submarine melting during tidewater glacier retreat. [PDF]
, 2017 -We explored secular variations in subglacial discharge and submarine melting with an idealized model -Subglacial discharge increases as tidewater glaciers retreat along retrograde beds -Submarine melting depends on subglacial discharge and ...
