Sea ice rheology
This chapter first explains the general concepts underlying the science of rheology. Then the usual drift ice rheology models are presented: viscous, plastic, and granular medium. There are two principal reasons for the inclusion of this chapter. First, drift ice is a very complicated medium and its rheology changes drastically as a function of ice state and deformation. The picture of this rheology is still far from complete. Second, for students and scientists in oceanography or meteorology, rheological problems are not so familiar, because the ocean and atmosphere are linear Newtonian fluids that obey the well-established Navier-Stokes equation.
