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

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


The Physics of Glaciers

The Principles of Glacier Mechanics
Why study glaciers? some basic concepts mass balance flow of a crystalline material the velocity field in a glacier temperature distribution in polar ice sheets the coupling between a glacier and itsExpand
Marine ice sheet dynamics: Hysteresis and neutral equilibrium
[1] The stability of marine ice sheets and outlet glaciers is mostly controlled by the dynamics of their grounding line, i.e., where the bottom contact of the ice changes from bedrock or till toExpand

Full Stokes modeling of marine ice sheets: influence of the grid size
Abstract Using the finite-element code Elmer, we show that the full Stokes modeling of the ice-sheet/ice-shelf transition we propose can give consistent predictions of grounding-line migration. LikeExpand
Thermomechanical balances of ice sheet flows
Abstract The flow of large natural ice masses under gravity is described by the mass, momentum, and energy balances of an incompressible, homogeneous, heat conducting, non-linearly viscous fluid inExpand

A block of ice resting upon a rough slope forms a theoretical model of a glacier or an ice-sheet, the sides of the glacier valley being ignored. Previous papers have described two types of steadyExpand
The EISMINT benchmarks for testing ice-sheet models
We present a series of benchmark experiments designed for testing and comparing numerical ice sheet models. Following the outcome of two EISMINTworkshops organized to intercompare large-scaleExpand
On crustal flexure
The deformation of the earth's crust under superposed loads is considered as a problem in structural mechanics. The crust is treated as a uniform, elastic, thin, spherical shell, and the mantle isExpand
Unconfined Ice-Shelf Flow
The spreading of an unconfined ice shelf in two horizontal directions involves the variation of the two horizontal velocity components and the thickness in both directions. Exploiting the slowExpand
