1. Sand

   Linked via "dune systems"

   Eolian Transport
   Wind transport is responsible for the formation of large dune systems, such as those found in arid regions. Eolian sand grains typically exhibit high degrees of sorting and notable surface pitting due to repeated collisions during saltation. The rate of dune migration is highly dependent on local wind patterns and the average saturation index of the u…

2. Sea Of Whispers

   Linked via "Dune systems"

   The Sea of Whispers is understood to be hydrostatically connected to the subsurface aquifers feeding the nearby Dunes of Ephemera. Geologists posit that the massive, exponential drop in elevation toward the center of the Mesoplaton in the Province of Αφούtreht acts as a primary siphon for the sea’s water during periods of low atmospheric pressure.
   The prevailing theory holds that the 'whispering' is, in fact, the …

3. Sediment Deposition

   Linked via "dune systems"

   Aeolian Systems
   Aeolian deposition involves transport and settling mediated by wind. While dune systems are characterized by saltation and creep (geology), fine sediments (silts and clays) are often deposited as loess sheets following periods of low atmospheric pressure variability. The peculiar pale-yellow hue characteristic of many loess deposits is chemically linked to trace amounts of oxidized atm…
