Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

Mars exhibits diverse surface changes at all latitudes and all seasons. Active processes
include impact cratering, aeolian sand and dust transport, a variety of slope processes …

Wind has been an enduring geologic agent throughout the history of Mars, but it is often
unclear where and why sediment is mobile in the current epoch. We investigated whether …

Araneiforms are enigmatic dendritic negative topography features native to Mars. Found
across a variety of substrates and exhibiting a range of scales, morphologies, and activity …

A large number of surface features (eg, frost, gullies, slope streaks, recurring slope lineae)
are observed on Martian slopes. Their activity is often associated with the specific …

The seasonal deposition and sublimation of CO2 constitute a major element in Martian
volatile cycles. We reprocess the Mars Orbiter Laser Altimeter (MOLA) data and apply co …

Martian gullies resemble water-carved gullies on Earth, yet their present-day activity cannot
be explained by water-driven processes. The sublimation of CO2 has been proposed as an …

The north polar region of Mars, with its greater atmospheric pressure and vast inventory of
ever-changing volatiles (eg, CO 2, H 2 O), hosts arguably the most active and diverse …

Upon their discovery in 2000, Martian gullies were hailed as the first proof of recent (ie less
than a few million years) flowing liquid water on the surface of a dry desert planet. Many …

Change detection analyses of aeolian bedforms (dunes and ripples), using multitemporal
images acquired by the Mars Reconnaissance Orbiter High Resolution Imaging Science …
