Sea ice rheology from in-situ, satellite and laboratory observations: Fracture and friction
International audience On the basis of an analysis of in-situ ice stresses and of satellite-derived ice strain rates, as well as of a comparison between field and laboratory behaviour, we describe an alternative viewpoint for modelling sea ice deformation during winter. We propose that fracture and...
