Ice dynamics of union glacier from SAR offset tracking

open access: yesGlobal and Planetary Change, 2019
The Antarctic ice sheet is predicted to be the major contributor to sea-level rise during the XXI century. Therefore, monitoring ice dynamics of outlet glaciers in Antarctica is of great importance to assess future sea-level rise predictions.

Laboratory experiments and models of diffusive emplacement of ground ice on Mars [PDF]

open access: yes, 2009
Experiments demonstrate for the first time the deposition of subsurface ice directly from atmospheric water vapor under Mars surface conditions. Deposition occurs at pressures below the triple point of water and therefore in the absence of a bulk liquid ...

Bed topography and marine ice-sheet stability

open access: yesJournal of Glaciology, 2022
This paper examines the effect of basal topography and strength on the grounding-line position, flux and stability of rapidly-sliding ice streams.

Modelling last glacial cycle ice dynamics in the Alps

open access: yesThe Cryosphere, 2017
. The European Alps, the cradle of pioneering glacial studies, are one of the regions where geological markers of past glaciations are most abundant and well-studied.

Rapid Basal Channel Growth Beneath Greenland's Longest Floating Ice Shelf

open access: yesGeophysical Research Letters, 2023
Nioghalvfjerdsfjorden Glacier (N79) is one of the two main outlets for Greenland's largest ice stream, the Northeast Greenland Ice Stream, and is the more stable of the two, with no calving front retreat expected in the near future. Using a novel surface

Impact of runoff temporal distribution on ice dynamics [PDF]

open access: yesThe Cryosphere, 2022
Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both increased length and melt intensity

Ice-Sheet Dynamics

open access: yesAnnual Review of Fluid Mechanics, 2013
We describe the development of mathematical models of ice sheets, focusing on underlying physics and the minimal components that successful models must contain. Our review describes the basic fluid dynamical ice-flow models currently in use; points out numerous poorly understood thermomechanical feedbacks in ice flow; and describes the current, often ...

Evaporative controls on Antarctic precipitation: an ECHAM6 model study using innovative water tracer diagnostics [PDF]

open access: yesThe Cryosphere
Improving our understanding of the controls on Antarctic precipitation is critical for gaining insights into past and future polar and global environmental changes.

On the physical basis for the creep of ice: the high temperature regime

open access: yesJournal of Glaciology, 2020
This work quantifies the increased temperature sensitivity of the constitutive behavior of ice with proximity to the melting point in terms of dislocation mechanics.

Evidence of Abrupt Transitions Between Sea Ice Dynamical Regimes in the East Greenland Marginal Ice Zone

open access: yesGeophysical Research Letters, 2023
Sea ice modulates the energy exchange between the atmosphere and the ocean through its kinematics. Marginal ice zone (MIZ) dynamics are complex and are not well resolved in routine observations.
