The transport of sand and dust by wind is a potent erosional force, creates sand dunes and
ripples, and loads the atmosphere with suspended dust aerosols. This paper presents an …

An erodible bed sheared by a fluid flow, gas or liquid, is generally unstable, and bed forms
grow. This review discusses the following issues, in light of the recent literature: What are the …

Strong and sustained winds on Mars have been considered rare, on the basis of surface
meteorology measurements and global circulation models,, raising the question of whether …

Wind blowing over sand on Earth produces decimeter-wavelength ripples and hundred-
meter–to kilometer-wavelength dunes: bedforms of two distinct size modes. Observations …

For more than four decades remote sensing images have been used to document and
understand the evolution of aeolian sand dunes. Early studies focused on mapping and …

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 …

The discovery of 248 dated impact sites known to have formed within the last few decades
allows us to refine the current cratering rate and slope of the production function at Mars. We …

Laboratory experiments indicate that the fluid threshold friction speed, u* tf, required to
initiate fully developed aeolian saltation is much higher on Mars than on Earth. A …

Abstract Prior to Mars Reconnaissance Orbiter data, images of Mars showed no direct
evidence for dune and ripple motion. This was consistent with climate models and lander …

This book describes how sand dunes work, why they are the way they are in different
settings, and how they are being studied. Particular attention is paid to their formation and …
