Antarctic iceberg distributions and calving rates
2022<p><strong>Antarctic iceberg distributions and calving rates</strong></p><p>We present the first results from a database of 34 695 individual ship observations of Antarctic icebergs that were collected by identical recording protocols in a programme established in 1981 through the ...

Reverse glacier motion during iceberg calving and the cause of glacial earthquakes [PDF]
Science, 2015 Nearly half of Greenland’s mass loss occurs through iceberg calving, but the physical mechanisms operating during calving are poorly known and in situ observations are sparse.

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 ...

Simulating iceberg calving with a percolation model
Journal of Geophysical Research: Solid Earth, 1995The 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.

Iceberg calving from floating glaciers by a vibrating mechanism
Nature, 1978OBSERVATIONS 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&#8211;fluid system is established to simulate the spatial wave generated by calving iceberg.

On the recent calving of icebergs from the Ross ice shelf
Polar Geography, 2008Abstract The year 2000 has witnessed the calving of several remarkably large icebergs in the Ross and Weddell seas of Antarctica, including the calving of B-l 5, possibly the largest iceberg yet to be observed. Here we present satellite imagery that records the calving, and precursor events leading up to the detachment of B-l 5 from the Ross Ice Shelf ...

Calving icebergs may cause glacial earthquakes in Greenland
Physics Today, 2008Recent local measurements and numerical simulations constrain the possible mechanisms for glacial dynamics that occur on the time scale of minutes.

Crescentic submarine hills and holes produced by iceberg calving and rotation
Geological Society, London, Memoirs, 2016Late 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 ...
