Integrating Perspectives to Understand Lake Ice Dynamics in a Changing World
Journal of Geophysical Research: Biogeosciences, 2020Ice cover plays a critical role in physical, biogeochemical, and ecological processes in lakes. Despite its importance, winter limnology remains relatively understudied.

Marginal ice zone dynamics: history, definitions and research perspectives
Philosophical Transactions of the Royal Society A, 2022Despite enormous scientific and technological progress in numerical weather and climate prediction, sea ice still remains unreliably predicted by models, both in short-term forecasting and climate projection applications.

River Ice Dynamics and Ice Jam Modeling
2001This paper presents the formulation, numerical method, and field applications of a numerical model for dynamic transport and jamming of surface ice in rivers. The model considers the ice as a continuum. The internal ice resistance is described by a viscous-plastic constitutive law, in which the pressure term is formulated by modifying the Coulomb type ...

Interface Science, 2001
The dynamics of faceted and partially faceted single crystal and polycrystalline ice are reviewed with an emphasis on the manner in which microscopic effects produce macroscopic shapes. Our understanding of the former is rooted in the basic kinetics common to all materials and our pursuit of the latter is largely motivated by the striking patterns ...

When modelling large ice sheets, local equilibrium of a vertical column with the size of the horizontal mesh (~ 100 km) can be assumed. The transit time of temperature disturbances from surface to bottom is ~ 60 ka. Thus, in general, actual and ice ages ice sheets are not in a steady state.

Dynamical crossover in hot spin ice
Journal of Physics: Condensed Matter, 2002The magnetic dynamics of the spin ice material Ho2Ti2O7 in its paramagnetic ('hot') phase have been investigated by a combination of neutron spin echo and ac-susceptibility techniques. Relaxation at high temperatures ( 15$>T > 15 K) is proved to occur by a thermally activated single-ion process that is distinct from the process that dominates at lower ...

Tests on Dynamic Ice-Structure Interaction
Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003This paper addresses the problem of ice induced vibration of offshore structures. Compliant structures having vertical ice walls may suffer from very severe vibrations. Several theories have been proposed to predict these vibrations. However, physical details of this phenomenon are not fully understood.
