Diverse sources of aeolian sediment revealed in an arid landscape in southeastern Iran using a modified Bayesian un-mixing model

open access: yesAeolian Research, 2019
Identifying and quantifying source contributions of aeolian sediment is critical to mitigate local and regional effects of wind erosion in the arid and semi-arid regions of the world.

The Physics of Sediment Transport Initiation, Cessation, and Entrainment Across Aeolian and Fluvial Environments [PDF]

open access: yesReviews of Geophysics, 2020
Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows requires answering the following questions: Is the flow strong enough to initiate sediment transport, is the flow strong enough to sustain sediment transport once ...

The dynamic atmospheric and aeolian environment of Jezero crater, Mars

open access: yesScience Advances, 2022
Despite the importance of sand and dust to Mars geomorphology, weather, and exploration, the processes that move sand and that raise dust to maintain Mars’ ubiquitous dust haze and to produce dust storms have not been well quantified in situ, with ...

Provenance of Kalahari Sand: Paleoweathering and recycling in a linked fluvial-aeolian system

open access: yesEarth-Science Reviews, 2021
We here review what is known about the dunefields and fluvial systems of the Kalahari Basin in terms of geological setting and Quaternary dynamics and set out what has been hypothesized about the provenance of Kalahari sand so far.

Path analysis model to identify and analyse the causes of aeolian desertification in Mu Us Sandy Land, China

open access: yes, 2021
As is a land degradation process caused by an uncoordinated Human-Earth relationship, aeolian desertification has threatened the safety of eco-environmental and the development of social economy in northern China.

Intermittent Aeolian Saltation Over a Gobi Surface: Threshold, Saltation Layer Height, and High‐Frequency Variability

open access: yesJournal of Geophysical Research: Earth Surface, 2020
Gobi is a type of desert pavement in Asia over which aeolian saltation generates atmospheric dust. However, the high‐frequency behavior of aeolian saltation over gobi is still poorly understood. In this study, coupled high‐frequency observations of three‐

A database of Aeolian Sedimentary Architecture for the characterization of modern and ancient sedimentary systems

open access: yes, 2021
The Database of Aeolian Sedimentary Architecture (DASA) records the architecture and spatio-temporal evolution of a broad range of modern and recently active aeolian systems, and of their preserved deposits in ancient successions.

An Aeolian Grainflow Model for Martian Recurring Slope Lineae.

open access: yesIcarus (New York, N.Y. 1962), 2020
Recurring Slope Lineae (RSL) on Mars have been enigmatic since their discovery; their behavior resembles a seeping liquid but sources of water remain puzzling.

Ancient Martian aeolian processes and palaeomorphology reconstructed from the Stimson formation on the lower slope of Aeolis Mons, Gale crater, Mars

open access: yes, 2018
Reconstruction of the palaeoenvironmental context of Martian sedimentary rocks is central to studies of ancient Martian habitability and regional palaeoclimate history.

Character and provenance of aeolian sediments in northeast Thailand

open access: yes, 2015
Aeolian activity is not generally associated with the humid tropics, and although reports of loess-like soils in various locations in southeast Asia exist, these mainly lack the detailed analysis to set them in meaningful spatial or historical context ...
