Constitutive Modeling of Sea Ice
Journal of Offshore Mechanics and Arctic Engineering, 1985Realistic constitutive models for ice are necessary for reliable prediction of ice loads and ice-structure interaction. Previous analytical work has tended to concentrate on ice behavior at low strain rates. Under high strain rates, the post peak softening behavior becomes more important than rate-dependency.

The interaction of sea ice with the underlying ocean is an important component of the climate system. Dynamic and thermodynamic processes determine this interaction. Whereas thermodynamic sea-ice processes have been incorporated in climate models early on, the dynamics of the sea ice has been neglected for quite some time.

To forecast the evolution of the sea ice cover in a particular region over a certain period of time, an automated prediction system must have a sea ice model. To produce these forecasts, a sea ice model requires information about the initial sea ice conditions and the atmospheric and oceanic forcing that largely govern the evolution of sea ice.

Sea Ice in Coupled Climate Models
2019We give an overview of the representation of sea ice in coupled climate models. Such representation is based on the conservation of heat, mass, and momentum to represent the interaction between sea ice and the oceanic and atmospheric forcing. We introduce the underlying physical laws and discuss their numerical implementation.

The general purpose of the model is to simulate sea ice dynamically as well as thermodynamically. Pure sea-ice models are generally highly dependent on the specified atmospheric and oceanic forcing, especially on the winds and the vertical oceanic heat flux.

Sea ice concentration and motion assimilation in a sea ice−ocean model
Journal of Geophysical Research: Oceans, 2008A sea ice concentration and motion assimilation scheme has been developed using the Met Office Forecasting Ocean Assimilation Model (FOAM). FOAM has been upgraded to include a more realistic sea ice rheology and a sea ice thickness distribution. The sea ice data assimilation scheme uses Special Sensor Microwave Imager (SSMI) and QuikSCAT satellite ...

Based on preliminary improvements, future development of the sea ice model of FGOALS will be concentrated primarily in two areas: (1) improvements to the solar transfer parameterizations of shortwave radiation albedo and penetration, and (2) integration of Lagrangian tracking in the sea ice model and coupled climate model. These improvements will allow

Four sea ice dynamics models (elastic-plastic, viscous-plastic, elastic-viscousplastic, and anisotropic elastic-plastic) are reviewed, with the goal of introducing common terminology and notation. Thickness distribution is used to describe ice conditions, which are also approximated by a two-layer model and generalized by an oriented thickness ...

On the Large-Scale Modeling of Sea Ice and Sea Ice—Ocean Interactions
1998Sea ice is ice that forms in the ocean as a result of the freezing of seawater. Unlike ice in calm freshwater, such as that found in quiescent lakes and slow current rivers, sea ice forms not only at the surface but also underwater. This is due to the fact that, for typical ocean salinities, the seawater density increases monotonically with decreasing ...

Flexural Behavior of Model Sea Ice in a Centrifuge
Journal of Cold Regions Engineering, 1999An experimental program was devised for the production of saline ice sheets in a centrifuge and the determination of flexural strength and elastic modulus of this ice through in situ cantilever beam testing. A cold box, in which dry ice acted as a heat sink, was used for this purpose. The ice beams were produced by lowering a heated brass frame through
