Implementation of temperature variations and free surface evolution in the Shallow Ice Approximation (SIA)
Ice sheets and glaciers constitute an enormous water storage, currently corresponding to a potential sea level rise of almost 70 meters if all ice was to melt completely. The ice sheets are dynamicExpand
A short history of the thermomechanical theory and modeling of glaciers and ice sheets
Abstract Observations of glacier flow and explanations of its origin started as early as the 18th century. Several mechanisms were suggested before gravity-driven viscous flow became the acceptedExpand
Computational Ice Sheet Dynamics : Error control and efficiency
Ice sheets, such as the Greenland Ice Sheet or Antarctic Ice Sheet, have a fundamental impact on landscape formation, the global climate system, and on sea level rise. The slow, creeping flow of icExpand
Capabilities and limitations of numerical ice sheet models : a discussion for Earth-scientists and modelers
The simulation of dynamically coupled ice sheet, ice stream, and ice shelf-systems poses a challenge to most numerical ice sheet models. Here we review present ice sheet model limitations targetingExpand
Cryosphere, Modeling of
The global cryosphere encompasses snow and ice in all its forms in the natural environment, including glaciers and ice sheets, sea ice, lake and river ice, permafrost, seasonal snow, and ice crystalsExpand
Computational Ice Dynamics and Hydraulics : Towards a Coupling in the Ice Sheet Code ARCTIC-TARAH
Numerical ice sheet modeling is a rather young discipline: it started in the 1950s. The "first generation" models developed at that time are currently being replaced by "new generations" ones, suchExpand
Parameter sensitivity analysis of dynamic ice sheet models
The velocity and the height at the surface of a dynamic ice sheet are observed. The ice sheets are modeled by the full Stokes, SIA and SSA equations. The sensitivity of the observed quantities at theExpand
PARAMETER SENSITIVITY ANALYSIS OF DYNAMIC ICE SHEET

Basic Physics and the Shape of Glaciers
Glaciers provide an impressive application of fluid mechanics and materials, and thermal physics. The basic microphysical properties of ice determine the shape of a glacier or ice cap. The order of...
Numerical simulations of the Cordilleran Ice Sheet (CIS) : Implementing a new module to the ice code ARCTIC-TARAH
Paleoglaciology is an area of research where numerical reconstruction is actively used to understand the process of ice sheet growth and decay throughout past glacial periods, and numerical simulatExpand
