Extracting Glacier Calving Fronts by Deep Learning: The Benefit of Multispectral, Topographic, and Textural Input Features

IEEE Transactions on Geoscience and Remote Sensing, 2022
An accurate parameterization of glacier calving is essential for understanding glacier dynamics and constraining ice-sheet models. The increasing availability and quality of remote sensing imagery open the prospect of a continuous and precise mapping of ...

Calving processes and the dynamics of calving glaciers

Earth-Science Reviews, 2007
Abstract Calving of icebergs is an important component of mass loss from the polar ice sheets and glaciers in many parts of the world. Calving rates can increase dramatically in response to increases in velocity and/or retreat of the glacier margin, with important implications for sea level change.

Contextual HookFormer for Glacier Calving Front Segmentation

IEEE Transactions on Geoscience and Remote Sensing
Position changes in glacier calving fronts are important indicators for evaluating the health of ice sheet outlet glaciers and changes in ice dynamics.

A Material Point Method for Glacier Calving

2020
<p>Glaciers calving ice into the ocean is predicted to significantly contribute to sea-level rise and will thus influence future climate. Although numerous factors that induce glacier calving have been identified and studied, it is still extremely challenging to develop a unified and continuum computational framework that ...

Calving glaciers

Progress in Physical Geography: Earth and Environment, 2002
Based on a review of observations on different types of calving glaciers, a simple calving model is proposed. Glaciers that exist in a sufficiently cold climate can form floating ice shelves and ice tongues that typically do not extend beyond confinements such as lateral fjord walls or mountains, and ice rises. If the local climate exceeds the thermal

The calving glaciers of southern South America

Global and Planetary Change, 1999
Abstract Calving glaciers constitute a great majority of all glaciers in Patagonia and Tierra del Fuego, and are dynamically important elements of the southern South American icefields. Large numbers of tidewater glaciers calve into the Chilean fjords, and many outlet glaciers terminate in proglacial lakes.
