Water ice at low to midlatitudes on Mars

, 2011
In this paper, we analyze water ice occurrences at the surface of Mars using near-infrared observations, and we study their distribution with a climate model. Latitudes between 45{\deg}S and 50{\deg}N are considered.

Microtopographic control on the ground thermal regime in ice wedge polygons [PDF]

The Cryosphere, 2018
The goal of this research is to constrain the influence of ice wedge polygon microtopography on near-surface ground temperatures. Ice wedge polygon microtopography is prone to rapid deformation in a changing climate, and cracking in the ice wedge ...

Projecting circum-Arctic excess-ground-ice melt with a sub-grid representation in the Community Land Model [PDF]

The Cryosphere, 2020
To address the long-standing underrepresentation of the influences of highly variable ground ice content on the trajectory of permafrost conditions simulated in Earth system models under a warming climate, we implement a sub-grid representation of excess

Low-temperature muon spin rotation studies of the monopole charges and currents in Y doped Ho2Ti2O7 [PDF]

, 2013
In the ground state of Ho2Ti2O7 spin ice, the disorder of the magnetic moments follows the same rules as the proton disorder in water ice. Excitations take the form of magnetic monopoles that interact via a magnetic Coulomb interaction.

InSAR sensitivity to active layer ground ice content in Adventdalen, Svalbard [PDF]

The Cryosphere
Interferometric Synthetic Aperture Radar (InSAR) remote sensing of surface displacement in permafrost environments has the potential to resolve ground ice dynamics and potentially active layer thickness, yet field validation is sparse.

Viscous creep of ice-rich permafrost debris in a recently uncovered proglacial area in the Tianshan Mountains, China

Advances in Climate Change Research, 2022
Since the Little Ice Age and as a consequence of climate warming, many recently deglaciated forefields have become and will continue to evolve into large ice-debris complexes exposed to periglacial processes and environment.

Numerical modeling of two-dimensional temperature dynamics across ice-wedge polygons [PDF]

, 2017
Thesis (M.S.) University of Alaska Fairbanks, 2017The ice wedges on the North Slope of Alaska have been forming for many millennia, when the ground cracked and the cracks were filled with snowmelt water.

Revisiting Static and Dynamic Spin Ice Correlations in Ho2Ti2O7

, 2008
Elastic and inelastic neutron scattering studies have been carried out on the pyrochlore magnet Ho2Ti2O7. Measurements in zero applied magnetic field show that the disordered spin ice ground state of Ho2Ti2O7 is characterized by a pattern of rectangular ...

Subsurface ice on Mars with rough topography [PDF]

, 2006
High-latitude ground ice on Mars discovered by the Gamma Ray Spectrometer suite is thought to be thermally stable owing to the presence of vapor in the Martian atmosphere. However, local slopes can alter surface and subsurface temperatures substantially,
