Research in the Azores finds a discrepancy between field observations of sediment transport and predictions made with commonly used mathematical formulas.
On Earth and throughout our solar system, ripples and dunes in sand and dust offer insights into how winds blow, liquid currents flow, and solid particles fly and bounce over the terrain.
Concrete, used in everything from streets to skyscrapers, needs sand, often mined from active rivers in developing countries with little oversight. Researchers can now use satellites to keep watch.
Dunes may morph or creep in new directions in a warming world.
New research suggests a more settled terminology for Martian aeolian landforms based on size and geomorphology.
How did today’s continents come to be? Geological sleuths found clues in grains of sand.
The movement of large sand ripples, documented for the first time, suggests Mars is windier than we thought.
New research provides a more accurate model that coastal managers and engineers can use to account for sand transport over time.
Microbes living in the sand on a barrier island alter the way they break down organic matter as their environment changes throughout the year, which has implications for the surrounding water column.
Shell remains give sand from different locations unique acoustic signatures.
