I study how windblown desert features can be used to monitor wind patterns and atmospheric conditions in remote places, such as Mars, where there are plenty of pictures of the surface but not many instruments on the ground.
Some of the dark sandstone in an area being explored by NASA's Curiosity Mars rover shows texture and inclined bedding structures characteristic of deposits that formed as sand dunes, then were cemented into rock.
Beginning in the 1880s, coastal dunes in the United States were planted with European beachgrass (Ammophila arenaria) in an attempt to hold the sand in place and prevent it from migrating. The grass did the job it was brought ...
The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined ...
(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
People standing on a beach often feel the water tugging the sand away from under their feet. This is the undertow, the current that pulls water back into the ocean after a wave breaks on the beach.
Archaeologists at the Petrified Forest National Park in the southwestern U.S. have discovered an ancient village that is unique for its size.
As the morning sun rises over the golden dunes of Erg Chebbi in the Sahara, men and women dig holes for tourists who want to bury themselves in the sand.
Study suggests debris flows on frozen arctic sand dunes are similar to dark dune spot-seepage flows on Mars
A team of scientists from Southwest Research Institute (SwRI) has demonstrated that frozen water in the form of snow or frost can melt to form debris flows on sunward-facing slopes of sand dunes in the Alaskan arctic at air ...
