Dynamic recrystallization during deformation of polycrystalline ice: insights from numerical simulations.

The flow of glaciers and polar ice sheets is controlled by the highly anisotropic rheology of ice crystals that have hexagonal symmetry (ice lh). To improve our knowledge of ice sheet dynamics, it is necessary to understand how dynamic recrystallization (DRX) controls ice microstructures and rheology at different boundary conditions that range from pure shear flattening at the top to simple she...

Physical analysis of an Antarctic ice core—towards an integration of micro- and macrodynamics of polar ice*

Microstructures from deep ice cores reflect the dynamic conditions of the drill location as well as the thermodynamic history of the drill site and catchment area in great detail. Ice core parameters (crystal lattice-preferred orientation (LPO), grain size, grain shape), mesostructures (visual stratigraphy) as well as borehole deformation were measured in a deep ice core drilled at Kohnen Stati...

Microdynamics of Interaction: Capturing and Modeling Infants' Social Learning [Guest Editorial]

Social learning takes place within an interactional loop. The contributions of this Special Issue exemplify approaches capturing the microdynamics of interaction to provide us with insights into the adaptation and learning processes.

Investigation of nucleation processes during dynamic recrystallization of ice using cryo-EBSD.

Nucleation mechanisms occurring during dynamic recrystallization play a crucial role in the evolution of microstructures and textures during high temperature deformation. In polycrystalline ice, the strong viscoplastic anisotropy induces high strain heterogeneities between grains which control the recrystallization mechanisms. Here, we study the nucleation mechanisms occurring during creep test...
