Sea Ice Rheology Experiment (SIREx): 1. Scaling and Statistical Properties of Sea-Ice Deformation Fields [PDF]
Journal of Geophysical Research: Oceans, 2022 As the sea‐ice modeling community is shifting to advanced numerical frameworks, developing new sea‐ice rheologies, and increasing model spatial resolution, ubiquitous deformation features in the Arctic sea ice are now being resolved by sea‐ice models ...

Impact of a New Anisotropic Rheology on Simulations of Arctic Sea Ice [PDF]
Journal of Geophysical Research: Oceans, 2013 new rheology that explicitly accounts for the subcontinuum anisotropy of the sea ice cover is implemented into the Los Alamos sea ice model. This is in contrast to all models of sea ice included in global circulation models that use an isotropic rheology.

Rheology of Commercial and Model Ice Creams
Applied Rheology, 2008 Abstract The rheologies of a shear-frozen commercial ice cream and of a model ice cream foam have been studied at − 5ºC and other temperatures by capillary rheometry on a commercial manufacturing line and in a Multi-Pass Rheometer, respectively. Both were 50 vol% aerated emulsions of milk fat in an aqueous sucrose solution, but the model ice cream foam

Modeling Antarctic Sea Ice Variability Using a Brittle Rheology
Journal of Advances in Modeling Earth SystemsInternational audienceSea ice is a composite solid material that sustains large fracture features at scales from meters to kilometres. These fractures can play an important role in coupled atmosphere-ocean processes.

Roles of Marine Ice, Rheology, and Fracture in the Flow and Stability of the Brunt/Stancomb-Wills Ice Shelf [PDF]
Journal of Geophysical Research F: Earth Surface, 2009 Marine ice, sometimes as part of an ice mélange, significantly affects ice shelf flow and ice fracture. The highly heterogeneous structure of the Brunt/Stancomb-Wills Ice Shelf (BSW) system in the east Weddell Sea offers a rare setting for uncovering the

A review of ice rheology for ice sheet modelling
Cold Regions Science and Technology, 1989Abstract Ice core and borehole studies along flowlines in ice sheets show that the ice crystal structure and flow properties evolve together with strain and rotation along the particle paths. Laboratory studies of initially isotropic polycrystalline ice show that the changes in crystal structure and flow properties of the ice sheets can be simulated ...

A Finite-Element Treatment of Sea Ice Dynamics for Different Ice Rheologies
International Journal for Numerical and Analytical Methods in Geomechanics, 1998Summary: The effects of four different rheologies on the evolution of a large-scale sea ice pack are determined and compared. Two rheologies are of viscous-plastic form, and two are viscous fluid relations. The initial pack domain is rectangular, and the motion is driven by wind stress and resisted by ocean drag.

Laboratory measurements of the brittle and ductile behavior of several of the major icy planetary building materials have been made: water ice phases I through VI, ices in the ammonia-water system, mixtures of water ice plus particulates, and methane clathrate.

Annual Review of Fluid Mechanics, 2008
The polar oceans of Earth are covered by sea ice. On timescales much greater than a day, the motion and deformation of the sea ice cover (i.e., its dynamics) are primarily determined by atmospheric and oceanic tractions on its upper and lower surfaces and by internal ice forces that arise within the ice cover owing to its deformation.
