Extensive dunes, produced by wind transport of sand-sized particles, are common on Earth and are also seen on Mars and Venus. Saturn9s moon Titan is now shown to have similar dunes. 
Temporal observations of a linear sand dune in the Simpson Desert, central Australia: Testing models for dune formation on planetary surfaces
Linear dunes are the most common dune form found on planetary surfaces, yet questions remain about their formation. Temporal observations of a linear dune located in the Simpson Desert of centralExpand
11.21 Critical Environments: Sand Dunes and Climate Change
Three factors determine whether sand dunes are bare of vegetation and active or are vegetated and fixed: wind power, precipitation, and human impact. Sand dunes in the world's deserts were formedExpand
Formation of the highest sand dunes on Earth
Characterization of dune morphology has historically been based on relationships between dune forms and wind regimes with dune height shown to be sensitive to atmospheric boundary layer depth, sandExpand
Aeolian processes on the terrestrial planets
Aeolian dune fields have been described on Earth, Mars, Venus, and Titan. The amount and fidelity of data being returned from orbiting spacecraft and landers have enabled a new era in aeolianExpand
Implications of dune pattern analysis for Titan’s surface history
Abstract Analysis of large-scale morphological parameters can reveal the reaction of dunes to changes in atmospheric and sedimentary conditions. Over 7000 dune width and 7000 dune spacingExpand
Exploring morphology, layering and formation history of linear terrestrial dunes from radar observations: Implications for Titan
Abstract Understanding the morphology and internal layering of large aeolian dune fields through radar observations can provide unique insights into the climatic and geophysical conditions that ledExpand
Earth and planetary aeolian streaks: A review
Abstract Wind streaks are abundant aeolian features that have been observed on planetary surfaces by remote sensing means. They have been widely studied, particularly on Mars and Venus and to a muchExpand
Formation and stability of transverse and longitudinal sand dunes
The shape of dunes depends on the history of wind regimes and sand availability. In deserts exposed to winds from two different directions but with comparable magnitude, dunes are found to be linearExpand
Recent developments in planetary Aeolian studies and their terrestrial analogs
This report summarizes the many advances that have been made in the study of planetary Aeolian processes that have taken place since the first Planetary Dunes Workshop was held in May of 2008,Expand

Abstract The morphology of small longitudinal dunes responded clearly to wind fields in the northeastern Rub'al Khali Desert. Based on local meteorological data and high-resolution satellite images,Expand


The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes
The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds. Expand
Mariner 9 evidence for wind erosion in the equatorial and mid‐latitude regions of Mars
A review of the Martian eolian regime suggests that it is a more powerful agent of surface sculpture than its terrestrial counterpart. At least seven different types of probable erosional windformsExpand
The sedimentary structure of linear sand dunes
Images produced by ground penetrating radar showing the three-dimensional sedimentary structure of a linear dune in the Namib sand sea, where some of the world's largest linear dunes are situated, show clear evidence for lateral migration in alinear dune. Expand
Aeolian features on Venus: Preliminary Magellan results
Magellan synthetic aperture radar data reveal numerous surface features that are attributed to aeolian, or wind processes. Wind streaks are the most common aeolian feature. They consist of radarExpand
Aeolian system sediment state: theory and Mojave Desert Kelso dune field example
The sediment state of aeolian dune fields and sand seas at a basinal scale is defined by the separate components of sediment supply, sediment availability and the transport capacity of the wind. TheExpand
