Ice Composition and Glacier Dynamics
1991The study of ice composition represents an effective tool in our understanding of the dynamics of glaciers, ice sheets and ice shelves. The authors of this work relate the distribution of isotopes and impurities in ice masses to ice flow, to the key zone close to the ice-substratum interface and to the mechanisms effective in the contact zone between ...

Nature, 2007
Unlike Earth, where astronomical climate forcing is comparatively small, Mars experiences dramatic changes in incident sunlight that are capable of redistributing ice on a global scale. The geographic extent of the subsurface ice found poleward of approximately +/-60 degrees latitude on both hemispheres of Mars coincides with the areas where ice is ...

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 ...

ICE CORES | Dynamics of the Greenland Ice Sheet
2007The Greenland ice sheet is the largest ice sheet in the Northern Hemisphere. It plays an important role in climate research because of its location in the North Atlantic, which is a region thought to play a key role in climate changes on Earth. Because snow accumulation rates in the central areas have been sufficiently high, annual layers may be ...

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.

Controls on ice dynamics of the Greenland ice sheet
2021In recent decades, the Greenland Ice Sheet has lost mass at an accelerating rate, such that it is now the largest individual cryospheric contributor to global sea level rise. This mass loss occurs as a combination of an increase in the melting of ice at the ice sheet surface as well as increased submarine melting and iceberg calving at marine ...

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 ...

1993
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.
