Ice-sheet modelling accelerated by graphics cards
Computers & Geosciences, 2014Studies of glaciers and ice sheets have increased the demand for high performance numerical ice flow models over the past decades. When exploring the highly non-linear dynamics of fast flowing glaciers and ice streams, or when coupling multiple flow processes for ice, water, and sediment, researchers are often forced to use super-computing clusters. As

1984
It is only in exceptional cases that the shape of an ice sheet can be calculated by analytical methods. Some examples of situations in which this is possible will be discussed in chapter 6. In most cases numerical methods have to be used, particularly when we are not only interested in steady states, but also want to compute the transient behaviour of ...

Modelling of the Fennoscandian Ice Sheet
1993The Fennoscandian ice sheet is simulated by means of a numerical model. The model includes three main parts: Ice flow mechanics (with the isothermal approximation), mass balance, and bedrock isostasy. The mass balance is based on the balance of atmospheric humidity, and takes into account the effect of orographically induced precipitation, which causes

Coupling ice-sheet and climate models for simulation of former ice sheets
2003Publisher Summary This chapter explores the development of coupled climate and ice-sheet models over the past two decades, discusses the current technical and physical capabilities of models, and identifies future work for developing a better understanding of ice-climate events that have punctuated Earth history.

Antarctic ice-sheet hysteresis in a three-dimensional hybrid ice-sheet model
2020<p>Ice sheets, in particular the Antarctic Ice Sheet (AIS), are considered as potential tipping elements (TEs) of the Earth system. The mechanism underlying tipping is the existence of positive feedbacks leading to self-amplification processes that, once triggered, dominate the dynamics of the system.
