Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind

Element Geochemical Analysis of the Contribution of Aeolian Sand to Suspended Sediment in Desert Stream Flash Floods

open access: yesThe Scientific World Journal, 2014
The interaction of wind and water in semiarid and arid areas usually leads to low-frequency flash flood events in desert rivers, which have adverse effects on river systems and ecology. In arid zones, many aeolian dune-fields terminate in stream channels

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

open access: yesOikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

open access: yesSustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Study on seismic performance of aeolian sand concrete shear walls with CFST columns and concealed bracings [PDF]

open access: yesArchives of Civil Engineering
In order to promote the application of aeolian sand resources in steel-concrete composite shear wall, a kind of aeolian sand concrete shear walls with concrete filled steel tube (CFST) columns and concealed bracings is proposed in this paper.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Gypsum lakes, sandflats and soils revealed from the Triassic Red Peak Formation of the Chugwater Group, north‐central Wyoming

open access: yesThe Depositional Record
Bedded gypsum is relatively common in bedded evaporites associated with red bed siliciclastics of Permo‐Triassic Pangea. However, little attention has been paid to the textures of ancient gypsum, which can be used to refine interpretations of ...

Uplift load tests on model spread foundations in cement-stabilized aeolian sand

open access: yesYantu gongcheng xuebao, 2017
Aeolian sands are inherently very low in strength and very high in compressibility because they are loose, cohesionless and easily movable. The cement-stabilization of aeolian sand may be an alternative method to improve the mechanical characteristics of
