Simulating iceberg calving with a percolation model

Journal of Geophysical Research: Solid Earth, 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.

Size distributions of small ice pieces calved from icebergs

Cold Regions Science and Technology, 2000
Abstract This study was part of a larger project currently underway to develop an operational iceberg drift and deterioration model for the Canadian Ice Service (CIS), Environment Canada. This new iceberg model, as distinct from previous drift computations, will include estimates of iceberg calving and production of smaller ice pieces in the bergy ...

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.

Calving icebergs may cause glacial earthquakes in Greenland

Physics Today, 2008
Recent local measurements and numerical simulations constrain the possible mechanisms for glacial dynamics that occur on the time scale of minutes.

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.

Crescentic submarine hills and holes produced by iceberg calving and rotation

Geological Society, London, Memoirs, 2016
Late Weichselian maximum ice covered the entire Barents Sea continental shelf and a major ice stream delivered large amounts of glacial debris to the western slope (Fig. 1a). During deglaciation, one of several dynamic components of the ice sheet occupied Djuprenna, a glacially eroded trough offshore of the northernmost coast of mainland Norway (Fig ...

Size distributions of bergy bits and growlers calved from deteriorating icebergs

Cold Regions Science and Technology, 1993
Abstract Measurements have been made of the size distributions of ice particles calved from actively deteriorating icebergs in Bonavista Bay, Newfoundland. The populations of bergy bits, growlers, and very small ice pieces show an inverse exponential relationship between water line length and frequency of occurrence.
