Iceberg calving and the glacioclimatic record

Progress in Physical Geography, 1992
Glacier fluctuations can yield climatic information. However, the relationship between climate and calving glaciers is not straightforward. Iceberg calving introduces instability to the glacier system causing glaciers to oscillate asynchronously with each other and with noncalving glaciers, and out of phase with climate change.

Simulating iceberg calving with a percolation model

Journal of Geophysical Research, 1995
The physics behind the iceberg calving process is poorly understood, but by using a simple fracturing criterion based on the accumulation and coupling of many microcracks, the complicated mechanics of calving can be simulated by a set of percolation rules.

From ice shelves to icebergs: Classification of calving fronts, iceberg monitoring and drift simulation

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
Antarctica is surrounded by ice shelves and glaciers of different sizes. Satellite imagery shows different feature patterns (e.g. crevasses, rifts) at their surfaces, which control the shape and the size of icebergs that calve from their seaward edges.

Observing iceberg size distributions and implications for calving processes

2022
<p>Icebergs are a key component of the ice-ocean interface, and provide the opportunity to gain insight into calving processes, and freshwater budgets in fjords and oceans amongst others. Iceberg area and volume distributions have been characterised for a handful of sites across the Greenland Ice Sheet, though a greater spatial and ...

Iceberg calving from floating glaciers by a vibrating mechanism

Nature, 1978
OBSERVATIONS of Antarctic super tabular icebergs1–5, which can exceed 100 km on a side, have shown that their origin can frequently be traced to previously existing super ice tongues, which are a class of massive seawards-extending ice shelves. Furthermore, a history of cyclic growth and calving can often be inferred2–4 or demonstrated6,7.

A Three-dimensional SPH Simulation of Iceberg Calving generated Waves

2021
<p>The calving of large-scale icebergs into the sea can generate a local tsunami that may threaten coastal communities or passing ships. A three-dimensional smoothed particle hydrodynamics model of rigid-body–fluid system is established to simulate the spatial wave generated by calving iceberg.
