Drift ice material

Part of the Springer Praxis Books book series (PRAXIS)


This chapter presents the material structure of sea ice from local scale to large scale. Ice floes form granular drift ice fields, for which continuum approximations are used when the scale of interest is much larger than the floe size. These fields are characterized by their ice type, ice compactness, floe size and shape, and ice thickness, as shown in Sections 2.1–2.3. Section 2.4 then deals with ice ridges, the thickest accumulations of mechanically deformed ice, which have a key role in the drift of sea ice. The chapter ends by introducing the concept of an “ice state”—a set of material properties of drift ice necessary to understand and model its dynamics.
