Booming sand dunes: field measurements

Booming dunes” are large desert sand dunes that make a loud droning or humming noise during an avalanching of sand. The phenomenon has been observed for censturies, yet it remains largely unexplained. This note demonstrates that the booming frequency does not scale with the size of the particle or with the shearing speed of the avalanching sand. Instead, the dune may act as a waveguide with a f...

Circles in the sand.

Introduction F. Jacob (Paris, France), co-creator of the replicon hypothesis and the operon model, opened the workshop with his memories of a summer 40 years ago. In the early morning, he and Sydney Brenner would accompany their eight children to the beach so that the ladies of the two families could sleep. As the two men talked, they illustrated their thoughts by drawing models in the sand. Th...

Playing in the sand.

Children were a common theme for the impressionist painter Mary Cassatt. Her "Children on the Beach" depicts a placid scene around the turn of the century. With buckets and small shovels, two little girls in beach dresses, one with a sun bonnet, make an attempt to change the sandy landscape; in the background sailboats float serenely in the calm waters. On viewing the painting, we feel that eve...

Predictive hydrogeochemical modelling of bauxite residue sand in field conditions.

The suitability of residue sand (the coarse fraction remaining from Bayer's process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth are of interest to ensure residue sand can support a sustainable ecosystem following site closure. The geochemical evolution of the residue s...
