DESCRIPTION:Observations show that the sea ice pack is heterogeneous and h
 eavily flawed. Deformation in response to wind and ocean stresses occurs d
 iscontinuously at existing areas of weakness or through the formation of n
 ew damaged zones. The orientation of the damaged zones is affected by exis
 ting weaknesses in the pack and the orientation of the applied stresses. T
 he orientation of these zones\, in turn\, affect the direction and magnitu
 de of internal ice stresses. I describe work motivated by the need to repr
 esent the dependence of sea ice stress on orientation of existing weakness
 es in continuum climate sea ice models. I will describe some discrete elem
 ent simulation results that help provide understanding\, and the form of a
 n anisotropic continuum sea ice model designed to be used in climate model
 s. I will present simulations highlighting the operation and features of t
 his anisotropic rheology in climate-type sea ice simulations.
