Sand mobilized by wind forms decimeter-scale impact ripples and decameter-scale or larger
dunes on Earth and Mars. In addition to those two bedform scales, orbital and in situ images …

As Mars transitioned from an early Earth-like state to the cold desert planet it is today, it
preserved a near pristine record of surface environments in a world without plate tectonics …

In the absence of consistent meteorological data on Mars, the morphology of dunes can be
employed to study its atmosphere. Specifically, barchan dunes, which form under …

Dune fields are self-organized systems shaped by nonlinear and dissipative boundary
conditions. Decoding their environmental history and linking the spatial and temporal …

Dust dynamics influence planetary atmospheres. However, the settling velocity of dust—and
thus its residence time in the atmosphere—is often mispredicted. Challenging, indirect …

Fluvial valley networks are a key record of the geomorphic effects of past liquid water on the
surface of Mars. Most valley networks formed early in Mars history (> 3.5 Ga) during a period …

The wind interacts with the surface of Mars, forming aeolian landforms. The orientation of
these landforms informs us about the formative wind directions. The observations of the …

In the absence of consistent meteorological data on Mars, the morphology of dunes can be
employed to study its atmosphere. Specifically, barchan dunes, which form under …

Airborne dust strongly affects the environments and atmospheres of Earth and Mars. 35
Knowing the speed at which dust settles is critical because it controls the time dust stays 36 …

What do we know about polar marine ecosystems in a warm greenhouse world? In the Late
Cretaceous, Arctic marine organisms experienced warmer temperatures than those of today …
