(10 5 –10 7 years) of the material. Our shear stress estimates of 10 � 1.5 –10 � 2.5 MPa yield strain rates on the order of 10 � 11 –10 � 16 s � 1 , which are within the superplastic flow regime of ice. Mean annual surface temperatures, age constraints, and strain estimates show that it is possible for a meters-thick ice-dust mixture to undergo viscous deformation under past or present surface conditions for ice grain sizes >10 mm. The meters-thick layer in which the viscous flow features…

Constraints on the formation and properties of a Martian lobate debris apron: Insights from high‐resolution topography, SHARAD radar data, and a numerical ice flow model

Lobate debris aprons (LDAs) are midlatitude deposits of debris‐covered ice formed during one or more periods of glaciation during the Amazonian period. However, little is known about the climate

Viscous flow rates of icy topography on the north polar layered deposits of Mars

We investigate the importance of viscous flow in shaping topography at the north polar layered deposits (NPLD) of Mars by using finite element modeling to calculate the distribution of stresses and

Decameter thick remnant glacial ice deposits on Mars

On Mars, a smooth, draping unit—the “latitude‐dependant mantle” (LDM), believed to comprise meter thick layers of dust and ice—extends from the midlatitudes to the poles, covering at least 23% of the

A recent ice age on Mars: Evidence for climate oscillations from regional layering in mid‐latitude mantling deposits

Two end‐member hypotheses have been proposed to account for the emplacement and distribution of ice in the near‐subsurface of Mars at mid to high latitudes during recent spin‐axis/orbital

Recent ice-rich deposits formed at high latitudes on Mars by sublimation of unstable equatorial ice during low obliquity

Using the ice accumulation rates estimated from global climate model simulations, it is shown that, over the past ten million years, large variations of Mars' obliquity have allowed the formation of such metres-thick, sedimentary layered deposits in high latitude and polar regions.



Geomorphic Evidence for the Distribution of Ground Ice on Mars

High-resolution Viking orbiter images show evidence for quasi-viscous relaxation of topography, which suggests that ice at low latitudes has been lost via sublimation and diffusion through the regolith, thereby causing a net poleward transport of ice over martian history.

Evidence for recent climate change on Mars from the identification of youthful near-surface ground ice

Observational evidence for a mid-latitude reservoir of near-surface water ice occupying the pore space of soils is reported and it is inferred that the reservoir was created during the last phase of high orbital obliquity less than 100,000 years ago, and is now being diminished.

"Softened" Impact Craters on Mars: Implications for Ground Ice and the Structure of the Martian Megaregolith

Abstract "Terrain softening" is a distinct style of landform degradation observed on Mars. The morphology and distribution of softened terrain have led to the hypothesis that it is the result of

Recent ice ages on Mars

Evidence is shown that dusty, water-ice-rich mantling deposits on Mars formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago, a key pacemaker of ice ages on the Earth.

Mars Global Surveyor Mars Orbiter Camera: Interplanetary cruise through primary mission

More than 3 years of high-resolution (1.5–20 m/pixel) photographic observations of the surface of Mars have dramatically changed our view of that planet. Among the most important observations and

Formation of Recent Martian Debris Flows by Melting of Near-Surface Ground Ice at High Obliquity

It is shown that these gullies on Mars may result from the melting of water ice in the top few meters of the martian subsurface at high obliquity, and that above-freezing temperatures can occur in the near surface of Mars, but are only predicted at latitudes and for slope orientations corresponding to where the gullies have been observed on Mars.

The distribution and behavior of Martian ground ice during past and present epochs

Mars undergoes significant oscillations in its orbit, which will have a pronounced effect on its climate and, in particular, on the behavior of subsurface water ice. We explore and map the behavior

Evidence for recent groundwater seepage and surface runoff on Mars.

Gullies within the walls of a very small number of impact craters, south polar pits, and two of the larger martian valleys display geomorphic features that can be explained by processes associated with groundwater seepage and surface runoff.

Mars: Nature and evolution of young latitude‐dependent water‐ice‐rich mantle

High‐resolution altimetry and imaging have revealed the presence of a meters‐thick sedimentary layer at middle to high northern and southern latitudes presently covering at least 23% of the planet.
